Hello,
I have recently started using enGrid for meshing, and find it rather useful. This far I have only used it for meshing simple geometry for simpleFoam, but I would like to add a rotating region using the MRF approach. Do you know if there is some way of defining cellZones for MRF using enGrid, or am I limited to snappyHexMesh?

Would it be possible to create the stationary region as one mesh file and the rotating region as another mesh file, merging these using mergeMesh, and then stitching the patches between regions using stitchMesh?
Do any of you know if the mesh of the two regions need to align in order to use the stitchMesh utility, or will the utility take care of this even if the discretization is not identical?

I am grateful for any input!
Best regards,
Adam
