Hi there,

I have a problem calculating the flow in a radial fan, typically used in HVACs. When using the multiple reference frame of rotations I got wrong results at the 'tongue': a huge vortex disturbs the whole flow structure. When doing a tansient analysis with arbitrary sliding mesh motion this vortex disappears and the solution looks very good. I am very grateful for any suggestions how to get the right results with MRF.

Thanks, Thomas
