Hi all, I am planning to install CFX on my system. But, I do not know anything about it....Does it have a built-in preprocessor, or do I need another software (Gambit for FLUENT), which is the latest verwion, is it compatible with windows etc etc etc????...any help would be greatly appreciated. Thanks in advance, Regards.

CFX has physical preprocessor it means that mesh must be created somewhere else. Best ways is using ANSYS software there is CFX-MESH, CFX-CAD2MESH and ICEM CFD. CFX-CAD2MESH is "light" version of ICEM (maybe I am a little wrong). CFX-MESH is product based on proprietary mesher from early version of CFX, but updated for use in ANSYS Workbench. Latest version is 10, and it compatible with windows (32 and 64 bits). CFX can read GridGen, Patran neutral, CGNS, NASTRAN, GridPro. Of course it reads ANSYS formats: ICEM, its own format and ANSYS. Fluent mesh can be read through ICEM, but ICEM has much more power than GAMBIT, so better use ICEM. IMHO.

Thanks a lot for the info deLuther...Does that mean that I can generate the model (and mesh it) in ANSYS and run the analysis in CFX?...as I already have ANSYS 8.0....and one more question...do I need an X server (or any other software) to run CFX?...Thanks again for the help!! Regards..

In France we have cfx for free with sufficient ANSYS licenses. It is good; sales guys don't really care as we can have fluent as well now....

H.M.

Yes, you can generate model in ANSYS, but creating CFD mesh in ICEM is a lot easier. But for simple geometries... why not? To get this mesh into CFX you will need to create 3D region(s) for flow and 2d regions for BC. Because CFX is 3D only solver. See CFX documentation. You do not need any X server, CFX has "native" win32 version. Just install and run.

You don't have cfx for free - all you have is the ability to run fewer ansys jobs than before because someone is using those licenses for cfx. If you had too many ansys licenses and were not using them, then you overpaid for ansys. Ansys does not give things away for free.

Actually it is possible, for the same amount of ansys license the sales guy can throw cfx licenses. It is standard practice now.
