KR468: Do I need to change my UDF if I want to run my calculation in the parallel solver? |
Some operations in UDFs may need to be parallelized (share information between processors) to get the right results when run in parallel. Some common examples include operations such as summation... |
KR469: Any differences in UDF usage between UNIX, Linux and PC? |
The same UDF can be compiled and executed in UNIX, Linux or PC environments. One distinction that can be noticed between environments is in the comment syntax. In some UNIX compilers, comment... |
KR470: What is the directory structure of libudf? |
See the attachment |
KR471: If I change something in my UDF, how do I recompile and relink? |
Compile the UDF and load it again. You may encounter an error when you try to recompile a UDF if your libudf is loaded into a case. In that case, go to Define > User-Defined >... |
KR472: I have a UDF for 6.3, do I need to change anything for R12 and are there any changes in the libraries? |
In most cases you will not need any changes in the UDFs that already work with Fluent6.3. However, for it to work with Fluent R12, they will need to be recompiled. |
KR473: Where can I access the UDF header files to look up more macros not listed in the manual? |
All the header files (those with .h extension) contain macros that can be accessed for UDFs. These files are located in C:Program FilesANSYS Incv120fluentfluent12.0.16src, or the equivalent... |
KR474: Is there any material on how to model IC packages within the ANSYS WB Environment? |
This IC packaging focused training covers the fundamental principles as well as the details of ANSYS Workbench based workflow for IC package reliability prediction. Thermal cycling simulation for... |
KR475: How is the ANSYS Workbench licensed? |
ANSYS Workbench itself is not licensed. It is included with most of our products including ANSYS FLUENT 12, ANSYS CFX, and ANSYS MECHANICAL.<br><br>FLUENT 12.0 as well as 13 can be... |
KR476: How can I specify a transient velocity profile to the moving wall using UDF? |
You can give transient velocity to the moving wall using a UDF. The UDF updates the wall speed internally according to user specified time variation. You need to specify the wall as... |
KR477: How can I enable smoothing for hex mesh? |
You can enable smoothing for hex mesh using the following TUI command:<br><br>/define/models/dynamic-mesh-controls/smoothing-parameter/spring-on-all-shape<br><br>Type ¿yes¿ for the... |
KR478: How can I post process particle tracks from FLUENT 12 in CFD-Post 12 under ANSYS Workbench? |
See attached file. |
KR481: Are there any Best Practices for Remeshing Boundary Zones in T-Grid? |
Please see the attached document |
KR482: Are there any Best Practices for creating Hexcore mesh in T-Grid? |
Please see the attached file. |
KR491: What is the easy way to open context-sensitive help? |
Within the Workbench, highlight the relevant cell and press F1. Similarly within other applications such as FLUENT, press F1 for the relevant help. |
KR492: When will the Workbench be available on Linux? |
Workbench will be released with ANSYS 12.1. |
KR493: TGrid: I have many zones which are intersecting but not connected. How do I create feature edges at intersection? |
To create feature edges for intersecting but unconnected zones (as shown below), use the following TUI command:<br>/boundary/remesh/create-intersect-loop<br><br>(see the image... |
KR494: I am new user for the wrapper, how should I start? |
A series of tutorials including video slideshows, printable instructions and example files can be found on the ANSYS Customer Portal.<br>To find the tutorials:<br>1. Log into the... |
KR495: TGrid: What default length should I give initially? How do I determine the sizes on different zones? |
The Default Length is the largest allowable cell length in the Cartesian grid. Depending on the shape and size of the input geometry, T-Grid automatically computes an appropriate value for the... |
KR496: TGrid: Do I need to perform some operations on faceted geometry before starting the wrapper? |
Yes. There are few manual operations required to prepare the geometry for wrapper. These include:<br>Checking for duplicate nodes and merging them.<br>Converting quad zones into tri... |
KR497: TGrid: What is region? How to create wrapper for specific region? |
After creating the Cartesian grid, the wrapper virtually partitions all the cells into several volumetric parts, based on the intersecting and isolated cells. These parts are called regions. They... |
KR498: TGrid: What is meant by leakage in the region ? How to locate it? |
When the underlying geometry, you are using to create the wrapper surface contains a hole whose size is greater than the size of the Cartesian cells in that zone, a leakage or hole is created in... |
KR499: TGrid: How can I check applied size on a particular zone? How to edit them? |
The zone specific sizes can be checked by clicking "List" on boundary Wrapper Panel.<br><br>(see the image attached)<br><br>The assigned sizes can be edited... |
KR500: TGrid: I am getting lot of crossovers, what do I need to check? |
Crossovers are unwanted faces that connect parts of the wrapper surface separated by a small gap.<br>To reduce the crossover occurrence, it is recommended to use smaller Min... |
KR501: TGrid: Imprinting is taking lot of time, what is wrong? |
There could be many possible reasons for taking long time for imprinting. Usually for Underhood kind of complex geometries take around 2 hrs for imprinting. If it is taking far more time than this... |
KR502: TGrid: How can I handle the high curvatures and closeness of components? |
Curvatures and closeness of components can be handled through Curvature and Proximity function available in Wrapper Panel.<br>The Proximity and Curvature size functions calculate the... |
