Hi everyone,

I was not sure where to put this question, but I hope to get some guidance from you.

I am converting a mesh from Fluent format to OpenFOAM. The mesh was originally created in ICEMCFD. For Fluent, we can define an "interface" boundary in the ICEMCFD for the boundaries we wish to use as periodic, and then change them to periodic inside the Fluent. I am not sure this step will be valid if at the end, I convert the mesh to OpenFOAM mesh, because the "interface" boundary is not recognized in the OpenFOAM I guess.

Have you had the experience of creating a mesh with periodic BC in ICEM and converting it to OpenFOAM?

I appreciate any comment and lead.

Thank you.

I think I just needed to add "neighbourPatch". It is fixed now.

Thank you all.

Hello.

Do you remember where you added the `neighbourPatch`? Did you add it directly in the .msh file or did you change the boundary conditions in the `boundary` file?
