Hai

I have a fluent Mesh which is to be used with OF 2.4.0. It has a solid and fluid region with conjugate heat transfer.

I generate mesh with ANSYS workbench.

used fluentMeshToFoam *.msh , fluent3DMeshToFoam *.msh fluent3DMeshToFoam *.cas -writeZones , fluentMeshToFoam *.cas -writeZones . None of these seem to work.

With .msh file it shows

Please find the link to both .cas and .msh file.. Could someone help with what the issue is.

Solution:
1. In ANSYS work bench name both solid and the fluifd region. Give name for both volumes
2. Remove the contact regions.
3. Define MEsh parameters for the Faces of solid region alone with the fluid region suppressed and vice-versa (both can be same or different).
4. Unsupress both and creat mesh.
5. Since the contact regions are removed their would be only 2 contact regions ( created by FLUENT itself). .
6. Name it as solid_to_fluid and fluid_to_solid.
7. Use fluentMeshToFoam *.cas -writeZones
8. Rename the interfaces as mapped wall and give necessary attributes.
9. Splitmeshregions
10. USe it for OF simulations
