SubscriberHey everyone, I am trying to rotate a ceiling fan using MRF approach. I have created the enclosures in design modeler and performed the needed booleans. I have the fan body around which i extruded (add frozen) enclosure as MRF, and I also have a wall like a test chamber adjacent to the fan, and then I created the outermost domain as well. I want to create mesh interface in setup using the "mrf_inner_wall" and "mrf_outer_wall" .After moving to fluent meshing, I enable dead zone for the fan blades cavity created in the MRF and the adjacent walls, but i select the fluid zone option for MRF zone (mrf_inner_wall), the external zone just attached to MRF due to boolean from external domain to MRF (mrf_outer_wall) and the whole outer domain itself. I get this error continuously during volume meshing:

Ansys EmployeeMRF approach works best with a conformal interfaces between the MRF and the adjacent enclosure.
I would recommend sharing topology between these zones and having an internal-type boundary between the two.
