foamiste is on a distinguished road
Hello foamers,

I was trying to convert my mesh established in Fluent to openfoam. It seems that the conversion was successfull BUT I have a problem concerning how to assign an interface in openfoam, after the conversion the boundary is defined as a patch.(see foamfile)
I notice that interface in Fluent is meant to reflect that the mesh isn't structured.

Could you please help me about what to define as boundary condition for the interface (mrf_interne-zone_de_contact-src with mrf_externe-zone_de_contact-trg)?

Thanks!


FoamFile
{
version 2.0;
format ascii;
class polyBoundaryMesh;
location "constant/polyMesh";
object boundary;
}
