OpenFOAM translation to ANSYS

Stoyan · October 12, 2016, 07:08

Hi everybody, new here so sorry if this is in the wrong part of the forum.

I'm currently doing a simulation based on the 2D steady case of "The ERCOFTAC centrifugal pump OpenFOAM case-study", but due to software-restriction I use ANSYS CFX instead. I'm very close to reproduce the results described in the report however I seem to stumble on the finish line. So right now I'm looking in to the different boundary conditions to see if there is something that I've missed.

So my question is quite simply, is there any list that compiles the diffrent boundary conditions in OpenFOAM and either their translation to ANSYS or some kind of explanation of them?

Not that I know of. All I suggest is to look in the documentation of both codes and see the mathematical differences in the boundary condition treatments for both codes.
