Ansys Fluent and Paraview
I don't know how many people want to do this, but chances are there is always someone...
So if anyone wants to run a simulation in Fluent and post-process in Paraview, the way that I've found to work is to export the solution data in Ensight format (binary). Once that's done, you then have to change the extension to ".case" (information I've found scattered over various other treads; didn't discover it myself). It then opens in Paraview, at least it worked for me. I tried impoting the .dat files from Fluent, but one they have loads of default variables I was not interested in, making it a very large file (200mb in my case, which times the number of time steps is a very large size), and two, I wasn't sucessful in doing so. But if anyone is sucessful I'd be interested in knowing. If anyone has any tips/best practise information I'd be really interested, as I'm new to Paraview. |
I have a 3D steady state simulation that I ran in Fluent and would like to analyse it using Paraview.
I tried different files to import it in paraview like .encase, .case and .cgns but all I can do is view surfaces. The contour symbol in the filter tool bar is not highlighted so I cannot view different contours. any help is appreciated. Thanks. |

As for importing steady state data (or one time step of a transient simulation), I think I've figured it out. With your .cas and .dat files in your working directory, open up the latest Paraview (3.14, haven't tried on earlier versions) and then open only the .cas file using the "Fluent Case Files" reader in the prompt box that pops up. I believe it automatically reads a data file of the same name. Once you import your data, you'll notice you can't create stream tracers or contours. This is because the data is Cell Data and contour/stream tracers require Point Data. Apply the "Cell Data to Point Data" filter and you should now be able to apply contours or stream tracers. I was also able to import into Paraview by exporting an Ensight file from Fluent but I'm not so sure that's the route to take with transient simulations. |
Fantastic !!! thank you very much. it worked.

Sure, no problem. If you ever find out how to load Fluent transient data into Paraview, please let me know. I guess I'll just keep searching. : /

My Paraview stops running as soon as a FLUENT.cas was selected?
WHY? Could you give me a hand? PS:win7 x64 Paraview 3.14.1 Fluent 13.0 |

I have exactly the same problem. When I try to open the .cas file the program does not respond anymore. My .cas file is around 750 MB |
steady fluent to paraview
Hi everyone,
I m trying to post process my steady fluent simulation using paraview for comparing the openfoam and fluent results. so i opened the fluent .cas file in paraview . using celldatatopoint data in filter option i got a good plot. but the problem i have here is that the velocity is shown as components of x ,y,z did anyone had the similar problem? Can someone help me. what am i missing here? |
I would suggest that you export as ensight gold data format. You will get a file called .encase which you can rename to .case and open it directly in paraview. This approach should work flawlessly
