The Stock Model is an additional data structure in your workzone which is distinct from the part geometry.
The Stock Model is used for calculating the state of stock on the part. The Stock Model can be used at any
stage of machining, however it is particularly designed for use at the roughing, re-roughing and semi-finishing
stages. The Stock Model can also be used as the Remachining Reference in all three remachining toolpaths
(Z-Level, Planar and Contour Remachining toolpaths).
There are two types of Stock Model :
q 2D Stock Model – used to machine the stock in the Z-axis of the original axis system. This
type of stock model cannot be managed when generating toolpaths with views to machine
undercut areas of the part.

http://www.cadfamily.com/a/CAE_FEA_CFD/CATOPO/Einfluss-der-Netzdichte-auf-das-Ergebnis-der-Topologieoptimi_6161.html
Generell gilt: Je kleiner die Elementkantenlänge ist, desto präziser wird die optimierte Struktur berechnet.
Wird bei der Berechnung die Entstehung von Strukturen (Rippen, Streben etc.) einer gewissen Größe angestrebt, sollte die maximale
Elementkantenlänge im Modell (3D-Netz!) diesen Wert nicht überschreiten (Mindestanforderung) oder nach Möglichkeit deutlich
unterschreiten.
CAST-Penalty: Examples
http://www.cadfamily.com/a/CAE_FEA_CFD/CATOPO/CAST-Penalty--Examples_6164.html
The value "Cast Penalty" controls the way, how the cast restrictions will be realized.
Small values force a thickness-like variation, large values force a more stamped-like solution.
The following pictures illustrate this behaviour (FILTER-RADIUS=0)
Mesh size influence on the results of the topology optimizat
http://www.cadfamily.com/a/CAE_FEA_CFD/CATOPO/Mesh-size-influence-on-the-results-of-the-topology-optimizat_6159.html
The more fine is the mesh, the more precise the optimized structure is being calculated.
When one aim that the optimized structure have ribs or bars of defined size, then the mesh size of the 3D-mesh should be lower then this
value (minimum requirement) or if possible several times lower.

1 Introduction
The CHEMKIN-PRO Input Manual is designed to serve as a reference to CHEMKIN-PRO
users who require more information about the input parameters needed in defining a
chemically reacting flow simulation. In particular, information about syntax and format
of chemical reaction mechanism input files, thermodynamic data, and transportproperty data are described in detail. In addition, detailed information about all of the
input parameters associated with reactor models, including default values and usage
guidelines, are included in the Keywords section.
The CHEMKIN-PRO Interface guides users through problem setup and execution, as
well as quick analysis through the graphical CHEMKIN-PRO Post-Processor. The
operation of the CHEMKIN-PRO Interface and Post-Processor are described in detail in
Getting Started with CHEMKIN-PRO. In some cases, however, users may wish to work
from the command line instead of the User Interface and manually assemble Reactor
Model input files. For this purpose, the CHEMKIN-PRO Input Manual describes the
necessary syntax and usage of the reactor-input Keywords, as well as a quick
reference of what keywords are available for each Reactor Model.

http://www.cadfamily.com/a/CAE_FEA_CFD/Chemkin/Chemkin-LPCVD-Thermal-Analyzer-and-Furnace-Manual_3262.html
Introduction
Chemical vapor deposition (CVD) is a chemical process used for the deposition of
thin films in the semiconductor and related materials industries. A common design
used for the deposition of such films is the multi-wafer low-pressure batch furnace,
shown schematically in Figure 1-1. In these reactors, up to several hundred silicon
wafers are stacked concentrically and processed in a single batch run. These lowpressure CVD (LPCVD) reactors are thus well suited to large-scale wafer production.
Originally, these “workhorses” of the silicon microelectronics industry had horizontal
racks of wafers, but modern tools have a vertical orientation that reduces the
“footprint” of the reactor on the factory floor.

http://www.cadfamily.com/a/CAE_FEA_CFD/Chemkin/Chemkin-Post-Processing-Manual_3263.html
1 About This Manual
This manual describes how to post-process the results of the CHEMKIN reactor
simulations. Section I focuses on the CHEMKIN Graphical Post-Processor, which is
launched from the CHEMKIN Interface. Section II provides additional post-processing
options involving the Export Solution Utility (GetSolution.exe) that are appropriate for
command-line usage and batch scripting.
1.1 Overview of CHEMKIN Post-Processing Options
The objective of post-processing is the analysis and/or extraction of data obtained
from the CHEMKIN simulations. The analysis may be as simple as comparing a set of
scalar values or may require 2D and 3D plotting and contour capabilities. In some
cases, CHEMKIN outputs are used as input to further processing steps and the postprocessing is focused on extracting these values and formatting them for the next
program in a sequence of manual or automated/iterative processes.

to open the Pre-processor.
1 2.2. Setting Simulation Controls
Click to enter SIMULATION CONTROLS.
In the menu, set the Number ofSimulation Steps to 100 and the Step Increment to Save
to 5. Set the Primary Die to Top Die since it is the Top Die that will be moving, and under
Solution Steps Definition, set With Constant Die Displacement to 0.015".

We will keep the default values and go to Billet window (See Figure 7a). Billet mesh can be
generated inside the template/wizard (brick mesh) or user can import a 3D-keyword file to read
in the mesh. For this lab we will generate the billet using wizard. A new feature has been added
to this wizard (only QT interface and not to Motif) which allows user to load material from a
"deform material library". Till now the only way to input material was from a user-keyword-file
"USER_HT.KEY". If you choose to load the material from material library then at the time of
Master file generation the wizard will also generate "CogBilMaterial.KEY" for billet material. A
similar provision has been made for Dies and Manipulators. Users still need to have
USER_HT.KEY in their problem directory because it is read in at each operation. Main purpose
of this is to provide user with certain action keyword reading facility. If you want to use all the
material data from the material library and do not need any action keywords at any particular
operation then just provide empty USER_HT.KEY in the problem directory. For this current lab
we will use the User keyword option for billet material. Copy the USER_HT.KEY to your
problem directory from the "labs" directory.
In the Billet Geometry window (See Figure 7b), choose the round cornered rectangle as the
cross section and enter a height/width of 20, a length of 60 and a corner radius of 2. Go to the
Billet Mesh window (See Figure 7c) and enter 100 for the number of mesh elements, 1 for the
size ratio and 14 for the number of layers. Click on the Generate Mesh button. Put 25000 for
remeshing number of elements. This number will be used to generate tetrahedral mesh in case
brick remeshing fails because of too much distortion.

2.3. Importing Dies
In the previous lab, a deformable workpiece was defined for the problem. Now it is time
to import the dies. At the bottom of the Object Tree, click the Insert object icon
twice – Top Die and Bottom Die will get added to the Object Tree.
2.3.1. Top Die
Highlight Object 2 in the Object Tree and change the Object Name to Top Die. Define
the geometry of the Top Die by clicking and then . Go to the
DEFORM3D\V6_1\Labs directory and open Block_TopDie.STL. The geometry of the
Top Die should be visible in the DISPLAY window. It is good practice to check the
geometry of an object after it is imported into DEFORM to make sure it doesn’t have any
problems. To check the geometry, click the button. A GEOMETRY
CHECKING window will appear which gives a summary of the object’s geometry (See
Figure 2.2). For an object that has a closed volume, there should be 1 surface, 0 free
edges, and 0 invalid entities (as circled below). Objects that are imported as surfaces and
not solids will have a free edge but should still only have 1 surface.
