HyperMesh Fluent-Steps

HyperMesh Collectors:create collectors containing only the elements to be exported,namely 3D linear elements(tets, hexas, piramids, pentas)and the associated 2D elements for all the subsets of the boundary that require a boundary condition other than wall(e.g.inlet,outlet, symmetry, etc).It is convenient to place the 3D elements in one or more collectors, and each set of 2D BC elements in collectors with the appropriate name(e.g. inletA, inletB,outlet, etc).The best approach to create BC collectors is to use the "^faces" collector, so that both 3D and 2D elements refer to the same node numbers,otherwise there will be problems when reading the mesh in Fluent.

Inventor-Broken Out Section Views

Most assemblies contain a significant number of what Autodesk Inventor refers to as Library parts.
Library parts are read-only parts that cannot be edited.Often parts contained in libraries are shared by multiple projects;that is to say,they are used in the design of multiple products. Most commonly,libraries contain standard hardware such as fasteners or purchased parts such as motors or hydraulic cylinders.In the case of very large assemblies worked on by multiple design groups(structural,electrical,hydraulics),a library may contain the baseline work of another design group.

Mass Calculation
HyperMesh templates calculate element area,volume,and mass,based upon solver-specific
attributes attached to the model.
To calculate the mass of a given component or element,the template must be loaded and have
*function()commands that assign area,volume,and mass to template variables(variable1=area, variable2=volume,variable3=mass).The mass calculation function for the PAM-CRASH template is in $hmdir/template/feoutput/pamcrash/include/function,where $hmdir is your HyperMesh installation directory.

Altair HyperMesh Interfacing with nSOFT
http://www.cadfamily.com/downinfo/303282.html
Guidelines for using the nSOFT Interface
Follow these steps when using the nSOFT interface:
1.Load the finite element model of the structure or component to be analyzed.
2.Apply the loads that represent the loading environment for which the fatigue life is to be
evaluated.
These loads can be static loads for a static finite element analysis with load histories supplied in nSOFT. The stress and strain tensor for each static loadcase can then be written for nSOFT from the fatigue panel.Or,the loads can be transient loads that can be analyzed with a transient dynamic finite element analysis.The stress and strain tensor for each time-step can then be exported to nSOFT via the fatigue panel.
3.Analyze the model using the NASTRAN or ABAQUS finite element solver.
4.Translate the finite element analysis results into the HyperMesh format (hmres) using the
appropriate HyperMesh translator.

The computers in the network must also agree on the following aspects of sharing the network:
•Rules for deciding when a computer may transmit on the network.When multiple computers share a data path,whether in a cable or wireless medium,the computers need to know when the path is available for transmitting.The Ethernet standard contains rules that specify when a
computer may transmit.
•A way of identifying a transmission's intended destination.In Ethernet networks,multiple computers may receive a message intended for one computer in the network. When a message arrives at a computer's network interface,the computer needs to know whether the message is intended for itself or another computer.Every communication in an Ethernet network includes a hardware address that identifies the Ethernet interface of the intended receiver. Some communications also use Internet protocols that contain additional addressing information,such as an addresses that identify the sending and receiving computers on the Internet and a port,or process,that receives the communication at the destination computer.

In the LightTools Core and Illumination modules,you can use parametric controls to manage model parameters.(See Using Parametric Controls to Modify Parameters on page 246 in the LightTools Core Module User's Guide.)In the LightTools Optimization Module, you can use parametric controls to expand the capabilities of an optimization process to go beyond optimizing or constraining
parameter values.Using aliases,numeric parameters, pickups, and parametric expressions,you can also optimize or constrain calculated values,for which you might otherwise need to write user-defined constraints or merit functions.
Calculated values could include such values as the distance between two points,the volume of an element, or the sag of a surface at a specified location,for example.

It is important to consider the electrode structure of the LED to produce accurate models.The electrode usually blocks the light emitted from the die,which can produce distinct patterns in the output beam.This is a critical consideration for applications where uniform illumination is needed. Most LED designs use a single circular electrode at the top. Many other electrode configurations exist, primarily to provide more uniform current densities.Uniform current density is important to obtain uniform luminance.Current-spreading layers are common in LEDs to produce uniform current density across the die.AlGaInP,AlGaAs,SiC,GaAsP,and GaP die(s)typically have one contact on the top and one on the bottom of the die.
The GaN/Al2O3 die typically has both contacts on the top.Figure 49 illustrates schematics of various electrode structures found in LEDs.

Concrete Construction Engineering Handbook
http://www.cadfamily.com/downinfo/302971.html
A brace is any structural member used to support another,always designed for compression loads and sometimes for tension under special load conditions.In formwork,diagonal bracing is a supplementary(not horizontal or vertical)member designed to resist lateral load.Form braces are frequently made of wood or steel.Commercial steel pipe braces in various diameters and wall thicknesses and load-rated for adjustable lengths are popular. Buckling strength of braces is always a primary design consideration.
Horizontal lacing,horizontal members attached to shores or braces to reduce their unsupported length,can thus increase the available load capacity.Both bracing and lacing must be adequately connected at each end.This can be accomplished with bolts,nails,and a variety of commercial devices,depending on the materials involved. When attaching braces to the ground,a buried or above-ground concrete mass known as a deadman is sometimes used (Figure 7.20).

Concrete PIPE Design Manual
http://www.cadfamily.com/downinfo/302972.html
This manual is a compilation of data on concrete pipe, and it was planned to
provide all design information needed by the engineer when he begins to consider
the type and shape of pipe to be used. All equations used in developing the
figures and tables are shown along with limited supporting theory. A condensed
bibliography of literature references is included to assist the engineer who wishes
to further study the development of these equations.
Chapters have been arranged so the descriptive information can be easily
followed into the tables and figures containing data which enable the engineer to
select the required type and size concrete pipe without the lengthy computations
previously required. All of these design aids are presently published in
engineering textbooks or represent the computer analysis of involved equations.
Supplemental data and information are included to assist in completing this
important phase of the project, and illustrative example problems are presented in
Chapters 2 through 4. A review of these examples will indicate the relative ease
with which this manual can be used.

ESD protection structure with embedded high-voltage p-type SCR
http://www.cadfamily.com/downinfo/302984.html
The high-voltage output cell of the automotive VFD driver IC fabricated in a 0.5-µm high-voltage CMOS process is shown in Fig. 1.In this VFD driver IC, the output pull-up function is realized by the high-voltage PMOS (HVPMOS),whereas the pull-down function is realized by the on-chip
resistor of 300 kohm for vacuum fluorescent display. The resistor is connected from the output pad to VEE of -40V for VFD applications.
The device structure of the HVPMOS is drawn in Fig. 2,where the high-voltage region is surrounded by the high-voltage (HV) P-well of lightly doped concentration with a specified clearance from the HV P-well edge to the drain P+ diffusion of the HVPMOS. Such a HV P-well with lightly doped concentration will provide the drain of HVPMOS with high enough breakdown voltage for VFD application.The breakdown voltage of the HVPMOS is specified to be higher than 45V for this VFD application.

In general,J-Link/J-Trace should be powered on before connecting it with the target
device.That means you should first connect J-Link/J-Trace with the host system via
USB and then connect J-Link/J-Trace with the target device via JTAG.Power-on the
device after you connected J-Link/J-Trace to it.
5.1.2 Verifying target device connection
If the USB driver is working properly and your J-Link/J-Trace is connected with the
host system, you may connect J-Link / J-Trace to your target hardware.Then start
JLink.exe which should now display the normal J-Link/J-Trace related information
and in addition to that it should report that it found a JTAG target and the target??s
core ID. The screenshot below shows the output of JLink.exe. As can be seen,it
reports a J-Link with one JTAG device connected.

USB and then connect J-Link/J-Trace with the target device via JTAG.Power-on the
device after you connected J-Link/J-Trace to it.
5.1.2 Verifying target device connection
If the USB driver is working properly and your J-Link/J-Trace is connected with the
host system, you may connect J-Link / J-Trace to your target hardware.Then start
JLink.exe which should now display the normal J-Link/J-Trace related information
and in addition to that it should report that it found a JTAG target and the target??s
core ID. The screenshot below shows the output of JLink.exe. As can be seen,it
reports a J-Link with one JTAG device connected.
Flash Loader Development Guide for IAR Embedded Workbench
http://www.cadfamily.com/downinfo/302867.html
A flash loader is usually a rather small program which can program a certain flash memory
device,or family of devices.The flash loader consists of a small set of functions, mainly for
erasing or writing designated portions of the flash memory. C-SPY downloads this program into
RAM (it must be linked to an address in RAM). To run the program, C-SPY positions the PC at
one of the functions in the flash loader, writes data and directives for that function into a RAM
buffer,and starts execution. When the function returns, execution will hit a breakpoint. C-SPY
will then know that the function has finished and can proceed to make further calls to continue
the flash loading process.In short,C-SPY calls functions in the flash loader.
The flash memory device configuration files
The flash memory device configuration file is an XML file (filename extension flash) which
describes for C-SPY all relevant properties of a certain flash device. For example, the base
address of the flash memory and details such as block and page sizes. The file also specifies
which flash loader to use.

After you drag a body, you can save the current configuration, i.e. the
position and orientation of the components,as a snapshot.Snapshots
capture the existing locked bodies,disabled connections,and geometric
constraints.
A snapshot can be used for the following purposes:
•A starting point for a motion run.
•To place an assembly in a particular configuration.
•Snapshots can also be made available as explode states in assembly.
As a result the drawing created from the assembly will have multiple
view state. Different position configurations can be displayed on one
drawing sheet in a painless manner.
When manipulating snapshots,you can
•Create multiple snapshots
•Remove snapshots
•Switch from one snapshot to another
•Update a snapshots to the current configuration
•Borrow part position from one snapshot to another
The following table lists the icons available for creating and manipulating
snapshots.

Seismic Design of Reinforced Concrete Structures
http://www.cadfamily.com/downinfo/302841.html
Because of the appreciable forces and deformations that can be expected in critical regions of structures subjected to strong ground motions and a basic uncertainty concerning the intensity and character of the ground motions at a particular site, a good design concept is essential at the start. A good design concept implies a structure with a configuration that behaves well under earthquake excitation and designed in a manner that allows it to respond to strong ground motions according to a predetermined pattern or sequence of yielding.

In this procedure, you will create a simple solid extrusion that represents
the lens of the cell phone. It is centered on horizontal and vertical axes
formed by the intersection of two of the datum planes. You'll see how to
quickly mirror drafted lines in Sketcher, so that mirrored halves are
constructed and constrained to always be proportional. You'll also see
how to add round features to edges. Finally, you'll see how to save a
Sketcher section for reuse in another part.

physics and engineering texts.
You can specify static and kinetic friction for your cam-follower or slot-follower
connection.
•The coefficient of static friction for two surfaces must be larger than the
coefficient of kinetic friction for the same two surfaces.
•The coefficient of static friction describes the amount of energy that is needed to
initiate movement in your model.
•The coefficient of kinetic friction describes the amount of energy that is lost to
friction while keeping your model in motion.

One engineer should be responsible for the overall design, including stability,and should ensure the compatibility of the design and details of parts and components even where some or all of the design and details of those parts and components are not made by the same engineer.
The structure should be so arranged that it can transmit permanent(dead) and variable
(wind and imposed)loads in a direct manner to the foundations. The general arrangement should
ensure a robust and stable structure that will not collapse progressively under the effects of misuse or accidental damage to any one element.
The permanent and variable load factors to be used for the proportioning of foundations
should be obtained from EC08 and EC76(see also Section 3.2.1).The factored loads are,
however,required for determining the size of foundation members and for the design of any
reinforcement.

Connection-The joint plus the region of the slab and beams adjacent to the joint.
Column-A cast-in-place vertical supporting element,including column capital if provided, with or without construction joints,designed to resist forces from the slab at the connection,and having a ratio of long to short cross-sectional dimensions not exceeding four.
Column capital-A flared portion of the column below the slab, cast at the same time as the slab,and having effecfive plan dimensions assumed equal to the smaller of the actual dimensions and the part of the capital lying within the largest right circular cone or pyramid with a 90-deg vertex that can be included within the outlines of the supporting column.

SAICE-Design Of Prestressed Concrete Flat Slabs
http://www.cadfamily.com/downinfo/302820.html
Reports 17 and 25 require a minimum prestress level of 0.7MPa. The CEB-FIP code requires 1.0MPA and the ACI 0.86MPa.In a lecture given some years ago it was suggested that less than 1.4 MPa was too low a prestress,1.4 to 3.5 MPa was the'proper'range,and over 3.5 MPa would cause excessive shortening. Many slabs are now designed with stresses less than 0.7 MPa.
It is the Committee's philosophy that there is a continuous spectrum of concrete from plain reinforced to fully prestressed concrete,and that there should be no arbitrary limits on prestress levels.
It is considered that prestressed flat slabs are essentially ordinary flat slabs,subjected to additional lateral loads from tendons,which reduce the effective load on the slab,and to longitudinal prestress which helps to reduce cracking.

The name of the assembler executable file has been renamed from aarm to iasmarm.
In your assembler source code, consider the following issues:
1 Modules
In version 5.x, neither the assembler nor the compiler can make a distinction between
program and library modules. If you want a module to be treated as a library module,
thus conditionally linked, you must place the module in a library.
This means that if you have used either the LIBRARY or the MODULE directive in your
existing assembler source code, these will no longer have any effect.
In version 4.x, you could define one or several assembler modules in each file. In version
5.x, there can only be one module per file. This means that you have to restructure your
files accordingly.

Using the ROM Image on DA830 with RTSC Content
http://www.cadfamily.com/downinfo/302563.html
There is an important limitation to consider when using the ROM image.Many of the module
configuration parameters for the modules in the ROM image have been frozen to specific
(usually default)values,and cannot be changed by your configuration.
The reason for this is an important optimization in RTSC code generation.When XDCtools
generate code based on the client’s configuration,the module configuration parameters are
generated as constants.The compiler can then fold these constants into the code,so that the
code is optimized as though it were written specifically for the client‘s configuration.
When the ROM image is generated, the code is frozen.So,to benefit from this important
optimization,the values of the module configuration parameters must be decided on and
sealed.

8-bit RISC Microcontroller CPU: AVR
The AVR uses a Harvard architecture concept with sepa-
rate memories and buses for program and data. The pro-
gram memory is accessed with a two stage pipeline. While
one instruction is being executed, the next instruction is
prefetched from the program memory. This concept
enables instructions to be executed in every clock cycle.
The fast-access register file concept contains 32 x 8 gen-
eral purpose working registers with a single clock cycle
access time. This means that during one single clock cycle,
one ALU operation is executed. Two operands are output
from the register file, the operation is executed, and the
result is stored back in the register file in one clock cycle.
The Timer and other I/O functions are located in the I/O
memory space. The 64 addresses of the I/O memory space
can be accessed directly as I/O registers or as memory
space.

Bitmap Source Module User's Manual
http://www.cadfamily.com/downinfo/302478.html
When rays are emitted from the bitmap, we want them to go toward the optical system. To ensure
that this happens, we must provide a target to the Bitmap Source Module to use for aiming rays.
This is similar to importance sampling in TracePro. Switch back to TracePro to verify that front of the lens is at about z = 8mm and has a radius of about 50mm. Imagine a circular plane target at the front of the lens, with radius equal to 50mm and located z = 8mm. This is the plane from which rays in the source file will be launched. The Bitmap Source Module will trace rays from the bitmap to this target plane, and store the directions and locations of the rays in the source file at this plane.
Therefore it is important that the target plane not be embedded in any geometry. This is in contrast to importance sampling in TracePro, in which importance sampling targets are often embedded in
the model.

How Does TracePro Implement Solid Modeling
TracePro is based on a specific solid modeling engine called ACIS, made by
Spatial Corporation. Using ACIS, TracePro can conveniently share solid model
data with any other software program that is based on ACIS. TracePro can also
exchange data with most other non-ACIS based CAD and analysis programs via
IGES, STEP and other CAD formats using optional translators. TracePro can also
import lens design files from popular lens design programs.
Any entities that you create in TracePro are referred to collectively as a model.
Contained in this model are the individual pieces of solid geometry that are called
objects. By using a solid modeling approach, TracePro requires that all solid
objects must be bounded by surfaces. Objects can be defined within TracePro, or
they can be defined elsewhere (as in a CAD program) and imported into
TracePro. Objects within the TracePro solid model can be manipulated in a
number of different ways including the action of combining two or more objects
into a single object so that the only surfaces the object now has, are the
bounding or outer surfaces of the object.

plate welded to beam web and welded to column flange
plate bolted in beam web and welded to column flange
angle section bolted in beam web and bolted in column flange
short endplate: welded to beam web and bolted in column flange

ESA-Prima Win Truss connections
http://www.cadfamily.com/downinfo/302323.html
The module Truss connections integrates the calculation of connections in truss structures in ESA-Prima Win. Welded connections in plane as well as spatial trusses consisting of rectangular and circular hollow sections, I and C sections are checked according to the latest regulations.
As the structural model and the internal forces are defined already, only limited additional input is required. The program is built up as a wizard, which will guide you through the different steps of the input and the calculation process. Most operations, e.g. the recognition of standard joints, are fully automatic.
This wizard approach and the integration of the connection calculation in ESA-Prima Win makes the design much easier and more efficient.

ESA-Prima Win Expert System Connect Frame
http://www.cadfamily.com/downinfo/302324.html
The expert system is used for all types of steel frame connections which are implemented in ESA-Prima Win: bolted, welded and pinned connections.
When a node is selected, the expert system searches the template library for matching connections.A list of matching connections and their unity check (actual internal force divided by allowable internal force) is given. The program considers several criteria to select matching connections: joint
type, geometry, cross sections, steel qualities, ... The list displays the name of the connection, the unity check, the bolt grade, the source from which the connection comes, ... The selected connection is drawn on the screen.
For welded and bolted beam-column and beam-beam connections, the unity check is based on the
moment capacity. For bolted base plate connections, the unity check is based on the moment
capacity and the normal force capacity. For pinned connections, the unity check is based on the
shear force capacity.
For each connection in the template library a priority (1 to 5) can be defined. This priority represents the user preferences: some companies will prefer connections with always the same bolt diameter,other companies will prefer a minimum number of bolts, ...

The simple expression stands for the maximum number of characters in the
STRING. All the characters of the ASCII code are permitted in a character string. A
string can also include special characters, for example, control characters and
nonprintable characters. You can enter these using the syntax $hh, where hh
stands for the value of the ASCII character expressed in hexadecimal (example:
'$0D$0AText' )
When you declare the memory space for character strings, you can define the
maximum number of characters that can be stored in the string. If you do not
specify a maximum length, a string with a length of 254 is created.
The simple expression stands for the maximum number of characters in the
STRING. All the characters of the ASCII code are permitted in a character string. A
string can also include special characters, for example, control characters and
nonprintable characters. You can enter these using the syntax $hh, where hh
stands for the value of the ASCII character expressed in hexadecimal (example:
'$0D$0AText' )
When you declare the memory space for character strings, you can define the
maximum number of characters that can be stored in the string. If you do not
specify a maximum length, a string with a length of 254 is created.

+I(add 16-bit integer numbers) adds the contents of ACCU 1-L to the contents of ACCU 2-L and stores the result in ACCU 1-L. The contents of ACCU 1-L and ACCU 2-L are interpreted as 16-bit integer numbers. The instruction is executed without regard to, and without affecting, the RLO. The status word bits CC 1, CC 0, OS, and OV are set as a function of the result of the instruction. The instruction produces a 16-bit integer number instead of an 32-bit integer number in the event of an overflow/underflow.
The contents of accumulator 2 remain unchanged for CPUs with two ACCUs.
The contents of accumulator 3 are copied into accumulator 2, and the contents of accumulator 4 are copied into accumulator 3 for CPUs with four ACCUs. The contents of accumulator 4 remain
unchanged.

SIMATIC PID Temperature Control Manual
http://www.cadfamily.com/downinfo/302346.html
Control Zone (CONZ_ON, CON_ZONE)
If CONZ_ON = TRUE, the controller operates with a control zone. This means that
the controller operates according to the following algorithm:
• If PV exceeds SP_INT by more than CON_ZONE, the value LMN_LLM is
output as the manipulated variable (controlled closed-loop).
• If PV falls below SP_INT by more than CON_ZONE, the value LMN_HLM is
output as the manipulated variable (controlled closed-loop).
• If PV is within the control zone (CON_ZONE), the manipulated variable takes
its value from the PID algorithm LMN_Sum (automatic closed-loop control).
Note
The changeover from controlled closed-loop to automatic closed-loop control
takes into account a hysteresis of 20% of the control zone.

SIMATIC System and Standard Functions for S7-300 and S7-400
http://www.cadfamily.com/downinfo/302347.html
AINFO parameters
AINFO is the source area for additional interrupt information. As far as the intelligent slave is concerned, you can fill this area with any values that you wish. However, if you are using a DP master of the S7 family, the additional information sent along with the interrupt must conform to S7 conventions.
If you send a diagnostic interrupt (ATYPE=1), then you are responsible for entering appropriate, relevant values in data record 0, and if necessary, also in data record 1.
The following table shows you a proposed set of S7-compatible entries. In this case, the "module fault" bit (see above) was already set. Up to actually naming the bit, this suggestion corresponds to the default assignment (the one existing after a POWER UP, after a STOP-RUN transition at the intelligent slave or a station return).

VERICUT Configure an NC Control
http://www.cadfamily.com/downinfo/302209.html
This session demonstrates how to customize an NC Control file to simulate how various
G-Code words and data formats that will be processed by an NC machining center. The
sample "modify_control.mcd" tool path file contains many conditions that are commonly
addressed via control customization, for example:
Differing word formats
Unaccounted for special characters that performs NC control functions
Variances in actions performed by specific G-Code word/values
Addressing unsupported G-Code word/values
The step at the end of the session shows how to save the control configuration in a
Control file. A project file containing a reference to the Control file is also saved enabling
VERICUT to be easily configured to interpret the G-Codes in this and similar tool path
files destined for the machining center. The default system configuration is for a 3-axis
mill, but also contains a variety of possibly unwanted job-related data. To begin control
configuration for use in VERICUT it is recommended to load a generic Project file so
that configuration begins from a known state, and without extraneous job data.

VMEbus Fast Data Channel Specification VXI-10
http://www.cadfamily.com/downinfo/302223.html
In a Normal channel the abort receiver sets the ABT, RDY, WDY and END bits to 0 (zero) and returns the channel to the Idle state. It discards any data which was received during the aborted transfer. The abort generator returns the channel to the Idle state when the ABT bit is returned to 0 by the abort receiver.
In a Stream channel the abort receiver sets the ABT bit to 0 but does not change the state of the channel;the channel remains in the Active state. It discards any data which was received during the aborted block transfer.
When the abort receiver is the servant and the channel was established with a Transfer To Servant command, the error receiver must pass the FDC area to the commander. If the abort receiver is the commander and the channel was established with a Transfer To Commander command, the error receiver must pass the FDC area to the servant. If the stream channel utilizes a channel pair then both FDC areasshould be returned as defined above.

VMEbus TCP/IP-VXIbus Interface Specification VXI-11.1
http://www.cadfamily.com/downinfo/302224.html
The routing of messages from the LAN to the appropriate VXIbus device takes place via the create_link RPC. This RPC is used to create a network instrument link. The created link is associated with a particular VXIbus device via the device parameter. This parameter is a character string which is parsed by the TCP/IP-VXIbus interface device to determine which VXIbus device the link is associated with.
RULE B.1.1:
A TCP/IP-VXIbus Interface Device SHALL support a device string of the following format:
[,]where:
- A name corresponding to the address of a single VXIbus interface. This name
SHALL uniquely identify the interface on the TCP/IP-VXIbus interface device.
- The logical address of a VXIbus device on the VXIbus interface. (optional)

VMEbus TCP/IP Instrument Protocol Specification VXI-11
http://www.cadfamily.com/downinfo/302227.html
B.2. CONNECTION MODEL
This section defines the connection model of the network instrument protocol, as well as the relationship between controllers, devices, network instrument clients, and network instrument servers. The term controller, as used in this specification, typically refers to the RPC client, while the term device typically refers to the RPC server. The only exception is when the roles are reversed for interrupts, which will be described further later in the specification.
As discussed in the overview at the beginning of this specification and shown in Figure B.1, the network instrument protocol uses up to three channels between the controller and the device for passing network instrument messages. A network instrument connection is this set of channels:
Core Channel: Used to transfer all requests except the device_abort RPC and the device_intr_srq RPC.
Abort Channel: Used to transfer the device_abort RPC (optional for client).
Interrupt Channel: Used to transfer the device_intr_srq RPC from the device to the controller(optional for client).

The PXI specification, now at revision 2.0, leverages the CompactPCI specification,
which defines a rugged form factor for PCI that offers superior mechanical integrity and
easy installation and removal of hardware components. PXI products offer higher and
more carefully defined levels of environmental performance required by the vibration,
shock, temperature, and humidity extremes of industrial environments. PXI adds
mandatory environmental testing, EMC testing, and active cooling to the CompactPCI
mechanical specification to ease system integration and ensure multi-vendor
interoperability.

Conditional directives
Use the #if...#else...#endif directives to control the assembly process at assembly
time. If the condition following the #if directive is not true, the subsequent instructions
will not generate any code (i.e. it will not be assembled or syntax checked) until a
#endif or #else directive is found.
All assembler directives (except for END) and file inclusion may be disabled by the
conditional directives. Each #if directive must be terminated by a #endif directive.
The #else directive is optional and, if used, it must be inside a #if...#endif block.
#if...#endif and #if...#else...#endif blocks may be nested to any level.
Use #ifdef to assemble instructions up to the next #else or #endif directive only if
a symbol is defined.
Use #ifndef to assemble instructions up to the next #else or #endif directive only if
a symbol is undefined.

IAR Embedded Workbench MISRA Reference Guide
http://www.cadfamily.com/downinfo/302183.html
Manual checking
There are several rules that require manual checking. These are, for example, rules
requiring knowledge of your intentions as a programmer or rules that are impractical to
check statically, requiring excessive computations.
Note: The fact that rule 3.6 is not enforced means that standard header files in a project
are not checked for compliance.
Documenting deviations
A deviation from a MISRA C rule is an instance where your application does not follow
the rule. If you document a deviation from a rule, you can disable the warning for
violations of that particular rule.
Note: Your source code can deviate from a rule as long as the reason is clearly
documented. Because breaking rules in a controlled fashion is permitted according to
the MISRA C guidelines, error messages can be explicitly disabled using the
#pragma diag_xxx directives.

IAR PowerPac TCP/IP Stack User Guide
http://www.cadfamily.com/downinfo/302184.html
MII / RMII: Interface between MAC and PHY
The MAC communicates with the PHY via the Media Independent Interface (MII) or the Reduced Media Independent Interface (RMII). The MII is defined in IEEE 802.3u. The RMII is a subset of the MII and is defined in the RMI specification. The MII/RMII interfaces can handle control over the PHY which makes it possible to configure select transmission criteria as line speed, duplex mode, etc.
In theory, up to 32 PHYs can be connected to a single MAC. In praxis, this is never done; only one PHY is connected.
To allow multiple PHYs to be connected to a single MAC, individual 5-bit addresses have been be assigned to the different PHYs. If only one PHY is connected, the IAR PowerPac TCP/IP driver automatically finds the address of it.
The standard defines 32 16-bit PHY registers. The first 6 are defined by the standard.

The difference between the alternative __xdata and __far memory allocation
functions and the standard functions is the pointer type of the return value and the
pointer type of the arguments. The functions malloc, calloc, and realloc return a
pointer to the allocated memory area and the free and realloc functions take a pointer
argument to a previously allocated area. These pointers must be a pointer of the same
type as the memory that the heap is located in, independent of the default memory and
pointer attributes.
Note: The corresponding functionality is also available in the DLIB runtime
environment.

IAR C/C++ Development Guide Compiling and linking
http://www.cadfamily.com/downinfo/302081.html
The compiler performs many transformations on your application to generate the best
possible code. Examples of such transformations are storing values in registers instead
of memory, removing superfluous code, reordering computations in a more efficient
order, and replacing arithmetic operations by cheaper operations.
The linker should also be considered an integral part of the compilation system, because
some optimizations are performed by the linker. For instance, all unused functions and
variables are removed and not included in the final output.
SCOPE FOR PERFORMED OPTIMIZATIONS
You can decide whether optimizations should be performed on your whole application
or on individual files. By default, the same types of optimizations are used for an entire
project, but you should consider using different optimization settings for individual files.
For example, put code that must execute very quickly into a separate file and compile it
for minimal execution time, and the rest of the code for minimal code size. This will give
a small program, which is still fast enough where it matters.
You can also exclude individual functions from the performed optimizations. The
#pragma optimize directive allows you to either lower the optimization level, or
specify another type of optimization to be performed. Refer to optimize, page 252, for
information about the pragma directive.

IAR Embedded Workbench Known Problems
http://www.cadfamily.com/downinfo/302086.html
EW17516
The Embedded Workbench IDE freezes or crashes when executing a Make command if the filename extension of any output file also
is a valid extension for an input file to the assembler or compiler.
EW17445
When a workspace is created on a computer with a source code control system installed, the SCC information is stored in XML
format in the .eww file. This causes problems if the workspace is moved to a computer does not use SCC.
The only way to remove the information is to edit the text of the .eww file.
EW17098
If the Auto indent feature is enabled, a ':' in a comment is interpreted as a label and indented accordingly.

Once inside the VERICUT Help, the top level topics that pertain to both Cutter Grinder
and standard VERICUT will show you how to locate the feature in both products. As you
get into lower level topics, especially the references to Using VERICUT sections, the
discussions are directed toward the standard VERICUT interface. The concepts will
apply to Cutter Grinder, but how you access the feature will be different.

void opapi_set_tool_change_setup_function(OPAPI_ToolSetupFunction
func_p)
Register user's tool change setup function with VERICUT. The tool change function
registered, func_p, should have the following declaration style:
typedef int (*OPAPI_ToolSetupFunction)(void *userData);
which returns 1 if tool setup is successful or 0 if tool setup failed. If failed, no
optimization will occur for the current tool. Therefore, if a tool does not need to be
optimized, just return 0 when func_p is called for this tool. This function should only be
called in opapi_setup() function. Once registered, the tool setup function, func_p, will be
called each time a tool change occurs.

In addition to streamlining the verification process, VERICUT dramatically boosts
productivity on the shop floor. Automated and user-selectable optimization settings in
VERICUT let you maximize the material removal process. The feed rate and cutting
speed of each NC program automatically adjust based on the depth, width, and angle of
each cut. In fact, you can even set VERICUT to compensate for dull or custom cutters or
other elements unique to your operation.
VERICUT simulates up to 5-axis milling, drilling and wire EDM operations, as well as
turning and combination mill/turn machining. With a complete line of specialization
modules for added features and functionality, VERICUT is truly the total simulation,
verification, and optimization solution for unleashing NC productivity.

The Cutting Technology Selection Dialogue is displayed.
There is no Cutting Technology available specifically for 5mm thick Steel.
We could create it using New and entering all of the necessary Technology information.
However it is much easier to make a Copy of an existing one and modify it to suit.

PEPS Using Special End Cut Shapes
http://www.cadfamily.com/downinfo/301946.html
In this Exercise we will make a join using a Q Angle of 45-degrees as shown in the bitmap
image. This joint will be created in such a way that it creates a 90-degree Corner, but this does not have to be the case, it can be used as an end to end joint as in Example 5.

PEPS Nesting Parts and Trimming End of Tube
http://www.cadfamily.com/downinfo/301947.html
In Example 4, four Parts were to be produced using a shared cut between Components and the
end of the Raw Material was deemed good enough not to need trimming.
If it was necessary to trim the end of the Tube this could be achieved by adding a Cut to the other end of the Component.
This would however mean that we would have duplicate cutting in three places.
So trimming the End off the Tube cannot practically be achieved by modifying the methods used in Example 4.
To achieve what is required, we will have to create a Dummy Component to which we can apply the Trimming Cut and then use the Component Nesting Option.

PEPS Nesting Parts Without a Common Cut
http://www.cadfamily.com/downinfo/301948.html
In Example 7, all parts had square ends so that they could be nested with no gap i.e. one cut cuts two sides.In this example we will nest more parts but there will be a gap between them and therefore no need for a dummy part.
Before we proceed with the nesting we will explain a little trick to save material.Example 6 had 45-degree mitres and if nested end to end would create lots of waste material.It would be nice if one of the parts could be rotated by 180 degrees to save material.

ANSYS Automobile Suspension Bracket Analysis
http://www.cadfamily.com/downinfo/301953.html
This exercise will analyze an automobile suspension bracket. The bracket is
mounted to the automobile frame in the center hole, and to the wheel linkage
on the front and rear holes.The objective of the analysis is to evaluate
stresses under a limit load condition.The bracket is expected to yield,
therefore a plastic analysis will be necessary.The Parasolid model will be
imported into ANSYS and shell meshed, and analyzed elastically entirely
within the MTB the first time through.We will then transition to ANSYS
Mechanical to perform a plastic analysis.

ANSYS Rocket Engine Turbopump Flowguide Analysis
http://www.cadfamily.com/downinfo/301954.html
In this exercise, we will perform a thermal transient/static structural analysis of
a rocket engine turbo pump flow guide. The flow guide redirects combustion
gases through the pump during operation. Before launch, the flow guide is
cooled to cryogenic temperatures as liquid oxygen is pumped through it.
During launch, the superheated combustion gases heat the flow guide from
cryogenic temperatures (-350F) to over 1400F in approximately 10-seconds.
Although there are negligible mechanical stresses on the part, thermal
gradients are very severe.
The rocket engine is part of a reusable vehicle, which is designed to last for 50
missions. Post flight inspections reveal that the flow guide develops thermo
mechanical fatigue (TMF) cracks in the guide vanes after only one flight.
The goal of the analysis is to determine the time point after launch that has the
highest thermal gradient through the wall of the flow guide, and perform a
stress analysis at this limiting point.

ANSYS Fighter Jet Vectoring Nozzle
http://www.cadfamily.com/downinfo/301955.html
In this exercise, we will perform a structural analysis of a vectoring nozzle used on
a high performance jet fighter engine.Today??s state-of-the-art fighter aircraft are
using vectoring nozzle technology to gain a performance edge over the
competition.Airplanes are propelled forward by the expulsion of exhaust from the
engine.Thrust vectoring is a method of changing the exhaust in a way that would
cause the aircraft to change direction in a more abrupt manner than can be done
with traditional control surfaces such as flaps (ailerons, elevators,and rudders).
The nozzle design in this exercise (figure below) is similar in concept to one used
in a current jet fighter engine in service today.It consists of a series of flaps
hinged to a ring (A) at the forward section, and connected to a secondary outer
ring (B)through a set of struts (C).Moving the outer ring forward or backwards
controls the throat area of the nozzle.Vectoring is accomplished by tilting the
outer ring,or moving it up/down/left/right relative to the engine axis.These
movements are controlled by a series of actuator arms connected to the outer ring
(not shown).

ANSYS Roots type Supercharger
http://www.cadfamily.com/downinfo/301956.html
The Roots type supercharger shown below is used to boost the intake pressure
of an internal combustion engine by approximately 12-15 PSI, drastically
improving the performance of the engine.The device consists of two rotor
assemblies turning in opposite directions.The air is pushed around the outside
of the rotors and out the bottom. Air can??t leak back up through the rotors due
to the close clearances between the rotors and the case.The outer surface of
each rotor lobe contains a Teflon seal strip to prevent leakage.In order to
reduce pulsing of the pressure, the lobes are often twisted along the rotational
axis, or helically, as shown below.

Dynamic Multibody Unit Injector System using ABAQUS/Explicit
http://www.cadfamily.com/downinfo/301774.html
The dynamic simulation of the UIS has been carried out for many years using the commercial
software MSC/Adams. Since version 11 of MSC/Adams Bosch engineers have been partly re-
placing the rigid bodies with flexible bodies.
The combination of MBS- and FEM-functionality is a trend which was picked up by Abaqus in
version 6. Through that development it is possible to define rigid bodies and joints (so-called connector elements). From version 6.2 on, the bug-fixing has reached a point where a complex, industrial application could be tackled.

Abaqus Modeling Implantable Medical Device-Tissue Interactions
http://www.cadfamily.com/downinfo/301772.html
There is a tremendous amount of information available to describe many aspects of the mechanical behavior of cardiovascular tissue (Fung, 1993). There are also many areas where more empirical information is needed to address some of the issues that medical device companies face.More research is needed in the area of diseased and healthy in vivo human heart tissue and vein properties and anatomies, for example. More information is also needed regarding the boundary conditions associated with various device-tissue interactions. However, even if all aspects of tissue behavior and device-tissue interaction were perfectly understood, it would be extremely difficult, if not impossible, to incorporate this understanding into workable FEA models.
