Hello,

I recently ran two different CFDs for a single-stage compressor, single domain and full annular rotor case. I created a mesh for the rotor domain using ICEM CFD, and for the stator I used TurboGrid.

In CFD-Post, I found a discontinuity between the periodic interface in the rotor domain when I drew contour plots of vorticity, pressure, etc. Raw properties like pressure, temperature look better than other variables like vorticity.

The periodic interface method was GGI, and I thought changing this method to 'Automatic' or '1:1' would make a difference. However, when I set it as 'Automatic' then the solver chose to use 'GGI' (it sort of makes sense, because it is automatic); when I set it as '1:1', it showed an error message while saving a def file and use 'GGI'.

When I created the mesh in ICEM CFD, I also set the periodic interface but it seems not to affect the result.

I used to generate a mesh using TurboGrid and this is very new to me.

Is it an inherited issue in CFX, or is there any other way to resolve it?
