Importing Ansys Mesh to Simscale

Hi.

I have this 2 cases in Simscale:
https://www.simscale.com/projects/sl_pez/prueba_openfoam__loc_v1/
https://www.simscale.com/projects/sl_pez/prueba1_loc-1port_v2/

I have made the meshes in Ansys (.msh) and converted them in OpenFOAM using the function fluent3dMeshToFoam. However, when I upload the meshes (folder constant) in Simscale, there are different zones and I don’t know how to simulate that (how to select the boundary conditions). I haven’t used the function fluentMeshToFoam because that created an error (due to internal faces maybe).

What can I do?

Thanks.
