Introduction to the CFX-Mesh Tutorials

Introduction to the CFX-Mesh Tutorials

The CFX-Mesh Tutorials are a set of tutorial examples which demonstrate how to set up the geometry and mesh for a variety of different problems. The tutorials cover most of the meshing functionality available in CFX-Mesh together with some of the most commonly-used geometry features from DesignModeler. Each example results in the creation of CFX-5 GTM file, which can be imported directly into CFX-Pre. You will find instructions for setting up CFD simulations using these meshes in the CFX-5 Tutorials which are part of the main on-line help for CFX-5.

Some of these tutorials require the use of Parasolid files (for geometry import). If you have not already obtained these files, they should be readily available from the CFX Community Website: go to http://www.ansys.com/cfx and follow the Community link. This site is available to all registered CFX users. If you have not already got a username and password, go to http://www-waterloo.ansys.com/cfx/community/apply.htm to apply.

The tutorial instructions are based on ANSYS Workbench 8.1, although they will contain notes when instructions would have been different in the previous version. If you still have an earlier version of ANSYS Workbench then you may be able to find tutorial instructions explicitly for that version on the CFX Community Website using the link above.

If you want to print out the tutorials, then we recommend that you follow the link to the CFX Community Website to download a package in pdf format, and use this for printing.
