Hi,
I'm modeling a Centrifugal Compressor, for which I'm using multiple frame of reference (frozen rotor approach). While defining mesh interface, two 'walls' are added in boundary conditions, which I can't change as Interface. (From the drop down list in BCs, Interface condition is missing). I'm getting unrealistic results. Kindly help

pakk will become famous soon enough
Check if the cell zones on both sides of that interface are set to "fluid" and not so "solid".
