CATIA Freestyle Shaper, Optimizer and Profiler
http://www.cadfamily.com/downinfo/300399.html
Freestyle Shaper workbench is used to generate Aesthetic Non-Associative (datum) 3D curves and surfaces from scratch and to dynamically deform and analyze all produced elements.
Designers can create flawless, styled shapes from scratch using three-dimensional free-form curves and surfaces or with digitized data.The Designer has total control over all levels of continuity up to G2 curvature continuity over these curves and surfaces.Freestyle Shaper creates math-free representation for all types of free-form curves, surfaces thus making product development process very intuitive.
It also allows for direct manipulation with propagation of surface modifications on all related topology.So, to create a surface, a designer may use Surface Based Approach directly to create surfaces, without creating the boundaries and curves OR may use Curve Based Approach to create the boundaries first and then create the surface based on these curves.

Impossible to find a consistent orientation except if the join operator manages to keep some edges as free sidesIn some cases you can get a result, if the Join operator has been able to keep superimposed edges as free edges (boundaries)Two possible orientations for surface 2, if the wrong one is kept, it will not be possible to add surface 3 to the join.
you must take into account the accuracy of the data to Join: if you choose a strict tolerance, the Join has many free sides and it takes time to correct themalso sometimes Join does not work with a strict tolerance (Join failure)On the other hand when you relax the tolerance, some gaps are hidden but the geometry still has gaps and may be unusable for later processingFor example gaps may cause visible marks on the manufactured partremember that a gap may be: finally Join removes all edges which are smaller than the merging distance, which can cause problems if the merging distance is too highThe suppression of small curves may later produce invalid faces (with self-intersecting edges)merging dist. = 0.001mm merging dist. = 0.01mm merging dist. = 0.1mm

Student Guide: Lesson 5- What is a Draft? (2/2)* The pulling direction defines the direction from which the draft angle is measured. It derives its name from the direction that the sides of a mold are pulled to extract a molding.* The draft angle is the angle that the draft faces make with the pulling direction from the neutral element. This angle may be defined for each face by creating separate draft features.* The neutral element is used to define the pivot hinge for the drafted surfaces. The drafted surfaces pivot about a neutral curve, the hinge, where it intersects the neutral element. The neutral element, usually a plane or face, can be the same reference used to define the pulling direction.The neutral element is displayed in blue, and the neutral curve is displayed in pink. The faces to be drafted are in dark red.The geometry that is selected as the Neutral Element remains the same during the draft operation (i.e. it is not affected by the draft).

Interactive Drafting is a drafting system that can be used in a standalone 2D CAD environment. It can be used for traditional drafting purpose i. e. for creating 2D drawings of the components for which you do not have 3D models.Simple 2D drawings can be created in Interactive drafting without a 3D model. These drawings can be used to express design ideas.
To complete a generative view with interactive elements.2D interactive functionalities can be used in an advanced production environment for the dress-up and annotation of drawings.
Sketching in the drafting workbench gives you the ability to create 2D shapes. A sketch is a rough drawing by nature however it is possible to create precise elements.
When first creating a sketch thought should be given to the basic shape of the profile and not precise measurements. Once the profile is created, constraints can be added to help better define the profile. Finally, by editing the applied constraints, the precise profile can be obtained.A typical approach to sketching is made up of three steps:Profile CreationCreating Sketch ConstraintsEditing Constraints

Place gate to achieve balanced fillingGate in thicker areasGate far from thin areasPlace gates to achieve unidirectional fillingAdd gates as necessary to reduce pressurePrevent overpacking by adding gates
Very balanced fill, Unidirectional orientation, possible packing variation
Mostly balanced fill, Radial orientation, possible warpage due to orientation
Mostly balanced fill, Radial orientation,Large weld line formed at near EOF
Unbalanced fill, Weld line forms early, Radial orientation
Gate in a thicker area to help pack that thicker area betterGenerally lowers pressure to fill the part
When there is significant changes in wall thickness, avoid gating close to thin areasThe polymer will favor the path of least resistance and will a difficult time filling the thin feature, if at all

Moldflow Making Accurate Plastic Parts
http://www.cadfamily.com/downinfo/300377.html
Plastic melts are very compressible at the pressures used in injection molding. As the ram moves forward, the material in the barrel is compressed so that the flow rate in the cavity is less than indication by the ram movement. As the ram slows down, the plastic expands under pressure.
Melt compressibility causes a smooth transition from mold filling to packing.
The molding process is frequently divided into two phases. Commonly injection molders will talk about the filling and holding stages because this corresponds to machine settings.
Experiments on an instrumented mold show this concept is far from the truth. Figure 1?C2 illustrates a simple mold with pressure transducers PT1, PT2, PT3 positioned as shown. The lines labelled PT1, PT2 and PT3 show the pressures recorded by these transducers during filling of the mold.

http://www.cadfamily.com/downinfo/300350.html
Warpage is caused by variations in shrinkage across the part. The principle causes of shrinkage variations are:Differential shrinkageDifferential orientationDifferential coolingFor midplane models, the procedure for determining the cause of warpage depends on whether or not buckling has been predictedFor Fusion models, procedure assumes no buckling
In the process settings of original automatic warpage analysisSet warpage analysis type to BucklingIn solver parameters, check the Isolate cause of warpage optionCreate copy of original study and give it a new name

UniSim Design Simulation Basis Reference Guide
http://www.cadfamily.com/downinfo/300358.html 1.2.2 Selecting Library ComponentsAs mentioned previously, library components are selected from the Components Available in the Component Library group, and placed in the Selected Components group. There are many ways in which you can select components for a component list.
Once you become familiar with the available methods for component selection, you can select the procedure that you find most convenient.The process of adding components from the component library to the Selected Components list can be divided into three sub-processes. By visualizing the process of component selection in this way, you are made aware of all the available possibilities offered by UniSim Design. You can then adopt the most logical and efficient approach to use each time you build a case.
For component addition to the component list, the following methods are recommended:1. Filter the library list.2. Select the desired component(s).3. Transfer the component(s) to the Selected Components list.

The combined feed stream enters an inlet separator, which removes the free liquids. Overhead gas from the Separator is fed to the gas/gas exchanger, where it is pre-cooled by already refrigerated gas. The cooled gas is then fed to the chiller, where further cooling is accomplished through exchange with evaporating propane (represented by the C3Duty stream).
In the chiller, which will be modeled simply as a Cooler, enough heavier hydrocarbons condense such that the eventual sales gas meets a pipeline dew point specification. The cold stream is then separated in a low-temperature separator (LTS).
The dry, cold gas is fed to the gas/gas exchanger and then to sales, while the condensed liquids are mixed with free liquids from the inlet separator. These liquids are processed in a depropanizer column to produce a low-propane-content bottoms product.

While UniSim Design was being developed, code was added to expose various objects in the program.
By using an Automation client like Visual Basic, the end user can write the code to access these objects and interact with UniSim Design. The end user does not need to see the UniSim Design source code or even understand what was required to expose the objects. All that is required is the knowledge of those objects that are available.
Automation works in a client/server fashion. A server is something that provides a service that can be used by clients if they know the proper protocols.
UniSim Design is an Automation server application. By writing a little Visual Basic code, it is possible to send and receive information to and from UniSim Design. The exposed objects make it possible to perform nearly any action that is accomplished through the UniSim Design graphical user interface.

12.12.3 Parameters TabThe Parameters tab allows you to define the entire transfer function G(s), by defining the integrator, delay, lag, lead, and 2nd order transfer functions. The Parameters tab contains the following pages:• Configuration•Integrator•Delay•Lag•Lead•2nd Order•Ramp•Rate Limiter
The last seven pages allow you to define the different transfer function terms. Each of these pages contains the Active Transfer Function group, which consists of a number of checkboxes corresponding to the available components of the Transfer Function. By activating the appropriate checkbox, you can include that term in the overall Transfer Function. When you activate individual functions on the Integrator/Delay/Lag/Lead/2nd Order/Ramp/Rate Limiter pages, the appropriate

GT-SUITE COOL3D Reference Manual
http://www.cadfamily.com/downinfo/300294.html
COOL3D is a tool that can be used to build 3D models of underhood thermal management flow systems that can be discretized and made into model files for use with GT-SUITE. It provides the ability to build the model in a 3D environment so that the full details of the model can be included. It also includes sophisticated discretization logic that is able to transform the 3D model into a model file that is compatible with the GT-SUITE software.
COOL3D can be used to build any flow system that contains only blockages, fans, heat additions, and heat exchangers. This manual describes the operations and components available in COOL3D. It is assumed that the user is already familiar with the GT-SUITE software package including GT-ISE and GT-POST. COOL3D will share concepts with both GT-ISE and GT-POST where possible to maintain consistency. It will also incorporate new concepts and methods that are unique to 3D modeling.

1.2 Importing Templates into the Project To open the template library, select Window and then Tile with Template Library. On the left side of the screen the template library will be shown. To remove this library, one can simply close the window. To reload the template library, simply select Window and then Tile with Template Library again.
The template library contains all of the available templates that can be used with the selected license. Some of these templates (those that will be needed in this project) need to be copied into the project before they can be used to create objects and parts. For the purpose of this tutorial, click on the icons listed below and drag them from the template library into the project library. To search for a particular template or object, ensure that the left template window (and not the right-side project window) is active and press Ctrl and f simultaneously on the keyboard. This will load the Find window in which you can search for a template or object by name, which is also accessible through Edit and Find Parts, Objects and Templates (Note: If on UNIX, consult the GT-SUITE installation notes for the steps necessary to make the drag and drop feature work correctly.)

In the worksheet matrix section, the Case pull-down determines which case data (Case Setup case) is displayed. The selection choices in this pull-down are determined from the operating point parameter(s) chosen during DOE Setup. The data may be sorted by any of the available columns by clicking on the column header . Each click on the header will toggle between an ascending sort and a descending sort.
The column labeled In/Out determines which DOE experiments will be included in the surface fitting calculations. Any experiment that is unchecked will be left out of the fitting process. This can be useful to eliminate "fliers" or other unwanted data. To select/unselect a large quantity of rows, highlight the desired rows using the mouse (any column) and then right click to with include or exclude data. The CTRL key may be held down during mouse selection to select discontinuous sets of rows.

1.2.1 Solver Changes that Affect Results - Cooling Systems and Thermal Management The following list comprises the most significant code changes made to V7.0 which may impact results.
It is recommended to review the following list to understand which changes may have an impact on a given model, as not each of the changes below will impact all models. Understand also that a combination of changes may affect a model without any way of generalizing what direction results may change.
• 'ValveThermostatMConn' and 'ValveThermostatSConn': The minimum lift opening was changed from 1.0e-5 mm to 1.0e-15 mm. A minimum lift opening of 1.0e-5 mm instead of 0 mm will yield the same results as in V6.2. • 'Valve*Conn' and 'BallValveConn' with Liquid Flow: An improvement was made to the calculation of pressure recovery in valve connections with liquid flows. The change in results increases with increasing pressure drop and is also affected by area ratio (square of effective diameter of valve relative to downstream flow part diameter). The change in results is maximized at area ratios of 0.5 and is 0 at area ratios of 0 and 1. For a given pressure drop the flow rate in V7.0 will be equal to or larger than 6.2.

When using X-Windows to display the graphics on another machine's display, both the client and server's GLX version must be at least 1.3 and have the required OpenGL version shown above. The hardware on the machine displaying the graphical image is the one that is important for the speed of updating the image. Network traffic or speed limitations may also affect the frame rate. We do not officially support any third-party X-Windowing software.
However, as a service to our users we have tested the following: Cygwin, Exceed, and Exceed Power Suite 2006. We have found that the base Exceed package does not support GLX 1.3 and does not work with the advanced 3D features. The Exceed 3D add-on which was tested as found in "Exceed Power Suite 2006" does meet the minimum requirements, however it gives ~20% slower frame rates compared to displaying graphics generated locally on the same machine.
The option "GLX 1.3 Support" must be enabled from Start> Exceed Tools> XConfig> Exceed 3D and GLX. Cygwin only has a GLX version of 1.2, so it does not work with most machines. It was found to work with a remote machine with a GLX version of 1.4 (RHEL4.0), but its frame rate is 50% slower than compared to the local machine. Again, the above products are not supported or endorsed.

GT-SUITE Simulink Coupling Tutorials
http://www.cadfamily.com/downinfo/300279.html
TUTORIAL 1: Coupling with Simulink The purpose of this tutorial is to show how to create and run a GT-SUITE/Simulink coupled simulation. It is assumed that the reader has basic knowledge of how MATLAB and Simulink operate. A 4-cylinder SI engine model, similar to the one created in Tutorial 4 for GT-POWER, will be controlled through the throttle so that the Brake Torque follows a desired profile.
Although this tutorial focuses on coupling a GT-POWER model with Simulink, the procedure is essentially identical for all other GT-SUITE products. Before going further, the reader is strongly encouraged to read the Advanced Simulation Topics Chapter in the User's Manual in order to ensure that all the installation prerequisites for coupling with Simulink have been met. 1.1 Building the GT-SUITE Model Launch GT-ISE and open the file /tutorials/SimulinkCoupling/01-Simulink/4cylSI-begin.gtm and save it as GTandSimulink.gtm. Drag the 'SensorConn' (including its def object), the 'ActuatorConn' (including its def object) and the 'SimulinkHarness' templates from the Control folder of the template library into the GTandSimulink.gtm file. Create two SensorConn parts on the map near to the EngineCrankTrain using the def object.
Connect from the EngineCrankTrain part to each of the SensorConn parts. For the first SensorConn part, select Avg. Brake Torque from the Output Signal Editor window that is displayed when the connection is made. For the second SensorConn part, select the Crank Angle. Create an ActuatorConn part, using the def object, on the map in line with the throttle. Finally create a SimulinkHarness part with the attributes shown in the following figure. Ensure the check box next to ??Exact Synchronization with Simulink?? is marked; other parameters for the SimulinkHarness can be set to their defaults. The map should now look like the image below.

Functionalorganisation is preferred, if many different parts of an organisation or many organisations areinvolved.In practice, all three kinds of structuring are used within one WBS. Project Management can be defined as planning, directing, and controlling resources(people, equipment, material) to meet the technical, cost and time constraints of theproject. 5 The primary reason why projects fail is insufficient effort in the planning phase.
Project Management thus is considered as very important.The SAP Project System enables close and constant monitoring of all aspects of a project byhaving constant access to data in all the departments involved.Project management can be subdivided into project planning, i.e. the task which will beundertaken before the project starts, and project controlling during the implementation of theproject.
Planning must include: organization C service process

• A Printed Circuit Board (PCB) Assembly is made of a product with Parts:•The first part is divided into Bodies: -The PartBody contains the Board geometry with one pad (main pad) and drilled holes for mounting the board and for the pins of the components -The other bodies contain the Constraint Areas that delimit areas for the components and electrical routing •The second group of parts contains the Electronic Components such as Resistors, Capacitors, switches, connectors, terminators,
You will learn the two methods to design a Printed Circuit Board:Create the PCB geometry in 2 steps:Design a pad with holes in the Part Design workbench.Use the features recognition in the Circuit Board Design workbench.
This method is mainly used when the board is designed by one designer (the mechanical engineer) and then exported to the ECAD software by another one (the electrical engineer).Create the board geometry directly with Circuit Board Design workbench using the same Part Design workbench features.

A catalog is a file that references many other objects such as parts or subassemblies. It helps find the right object among thousands of alternatives as fast and as easy as possible. It also avoids the redesign of objects that already exist.
A catalog has a tree structure and is organized in chapters and subchapters and can include keywords to classify objects (see example below)
The default catalog created by the Circuit Board Design workbench includes only one chapter called Components. Before storing a CATPart file as an Electrical Component in the catalog, it must first be created with the Circuit Board Design workbench.

As a general rule when designing in context, the component created within the context of an assembly is unique to the assembly and should not be inserted into another assembly nor moved to another position.
However, if your design requires the component be moved, you must break the external references. This is done by isolating the feature.Identify how to isolate features.Once the feature has been isolated it behaves as a regular independent feature which can be modified normally.

The case study for this lesson is the Base part used in the Drill Press assembly, shown below. This case study focuses on incorporating the design intent when creating the drawing for the part.
The drawing should be created using an ISO standard.• Standards are predefined formats for dimensions, annotations, and views, which provide a consistent interpretation of information.
The drawing should contain one view that shows hidden lines and axis.• The display of these items in a single view enables a better understanding of the model by showing depth and internal features.The drawing should contain a title block.• This is typically required with any drawing.The base drawing must meet the following design intent requirements:

What is Knowledge Expert?Knowledge Expert enables users to define generic rules and checks specifications for classes of objects and store them in a base. These rules and checks can then be used to monitor the actions of every designer in the company.
As geometry is created or changed, the system uses the rules and checks to ensure compliance to corporate standards.When a rule or check is violated, corrective actions can be recommended or automated using VBScript macros, texts or linked to URL files.With KWE, corporate knowledge can be shared throughout the company in rule bases that can be applied to models. Those rule bases are stored in documents that can then be imported.
KWE offers report capabilities in output formats such as HTML, XML or TXT enabling, for example, to publish customized reports of rule and check violations.

http://www.cadfamily.com/downinfo/300250.html
Introduction to Generative DraftingThe 3D environment gives designers a very efficient and flexible tool to create parts and assemblies; however, it is often necessary to convey this information with 2D drawings of the components to communicate manufacturing information.
Student Guide: Lesson 10- General ProcessThe creation of a drawing for parts and assemblies can begin at any time in the design process. CATIA maintains an associative link between a drawing and the parts and assemblies it references. As the 3D part and assembly models evolve, the drawings automatically show the updated geometry.
