I am trying to model a rotor in steady state using a mrf, but the mrf-zone intersects other parts of the geometry because of their proximity with the rotor.

To get around this I was wondering if overset meshing can be used.

In my case (looking at the rotor in isolation), I have this cylindrical overset-zone, with an MRF applied to it (P1).

Mapping background mesh (P2)
Mapping rotor/front mesh (P3)

The overSimpleFoam simulation seems to run fine but the forces are way off (the viscous forces predictions especially are too big).

Does anyone know if this is a feasible approach?

Did you able to find a solution?
