Hi all,

For the thesis of my bachelor study Mechanical Engineering (University of Applied sciences) I am assessing the possibilities of using OpenFOAM in stead of Fluent. To effectively compare results (contour plots, velocity fields, pressure fields etc.) I would prefer post-processing in CFD post or Fluent so that the color scheme and image lay-out are identical.

I have (as far as I can tell) successfully used the foamMeshToFluent and foamDataToFluent command. More precisely I made my mesh in Ansys Mesh Modeler and saved it in ASCII format and successfully imported it to OpenFOAM (with the fluentMeshToFoam utility). This is what I have done step by step:

-Model mesh in Ansys mesh modeller, save in ASCII format.
-Import mesh in OpenFOAM (fluentMeshToFoam utility).
-Performed a seemingly successful K-Epsilon RNG simulation within the HelyxOS environment.
-Checked results in paraView (Looks allright).

Now I want to post-process my results on Win7 with Ansys CFD Post or Fluent (since that utility is available). Here is what I have tried so far:

-Export the .dat file with foamDataToFluent and exported the mesh with foamMeshToFluent to get the .msh mesh file.

Opening the .msh file in Fluent(Win7, different machine) works, I can see the mesh and it looks fine. All faces (inlet, outlet, symmetry) are defined and I set Fluent to K-Epsilon RNG so it has the correct variables available. Now when I try to import the .dat file Fluent gives the follow error:

''Warning: case and data files are inconsistent zone 10[xxxx,xxxx] data [xxxx,xxxxx]"

This error is repeated for all zones in the mesh.

Hope you guys can help! Thanks in Advance,

Joris

BTW: I'm not using cellzones, there is only one mesh region.

Hi Guys,

The problem seemed to be that I was running Fluent in parallel. I started a version of Fluent in serial and then it loaded in the results.

Right now I'm not actually post-processing in Fluent yet. I'll give updates and how it progresses.
