profile BC

June 21, 2005, 06:00

Hi,

we want to use profile boundary condition at inlet to diffuser. We have results from the impeller and we use outlet velocity profile as intlet boundary condition to diffuser. We follow method described in CFX-Help and when we see this imported profile to the inlet of diffuser it isn't the same as in the outlet of the impeller.

We haven't the same mesh at these two boundaries. Is it the problem?

Thanks for your help.

you must have the same physiscal plane (surface) for booth boundary conditions.
