Hi,

I made an hybrid mesh using ICEM-CFD and the interface between the structured and unstructured mesh shows up as an boundary field, while it should be an internal face. Does anyone know how to make it an internal face by toposet or boundary conditions?

The boundary field looks like this:


PHP Code:

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

This problem was solved by setting the boundary field INT_FACES as an interior face in ICEMCFD
