code_saturne User's Forum

Hello everyone,

I'm using Code_Saturne 3.0. I would like to import I-deas (.unv) mesh file and set boundary conditions in GUI of Code_Saturne.

I could import attached I-deas file into Code_Saturne. The mesh file has information of node positions and node groups for inlet, outlet, and wall. I would like to set boundary conditions using the node group information. However, I could not find out the solution to set boundary conditions using the node group information in GUI.

Please let me know, if you have any idea.

Best regards,
Junichi

Hello,

Code_Saturne ignores groups/colors defined at nodes (except for the CGNS format), so you need to define groups of colors at boundary faces, not vertices.

Under I-deas (at least in the old versions we had some years ago), this was done adding "surface coating" to the volume mesh.

Hello Yvan,

Thank you for your help.
I'm using Autodesk Simulation CFD as a meshing software. The software can export only I-deas format mesh file.
I tried to change format of mesh file from I-deas to CGNS using Salome 6.6.0. This way works well. I could import groups at boundary into Code_Saturne.

Best regards,
Junichi
