Mesh Interface Problem

ssheshan · April 17, 2015, 05:24

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

Check if the cell zones on both sides of that interface are set to "fluid" and not so "solid".

I did. Its fluid on both sides

what do you see in drop list!? do you see whole of BCs!? or only 5 BCs? are there pre. inlet, vel. inlet and other BCs?

All except 'Inerface'
