Unable to switch from Rotating Reference Frame to Mixing Plane
 

Hi All,

I am trying to implement a mixing plane between a radial impeller and diffuser passage. I have a solution using a rotating reference frame for the impeller zone, but when I then define a mixing plane (changing the interface boundaries to a pressure outlet and mass-flow inlet) at this interface, FLUENT crashes and gives a number of error messages, including "Stack backtrace generated for node id 3 on signal 11"

I am using the pressure based solver, compressible flow w/ k-w SST turbulence model. If anyone has experience with this situation, any advice would be appreciated.

Thanks in advance,

Ben
