When importing a multi-domain mesh from ICEM CFD to CFX-Pre the mesh on the domain interfaces look like a checkerboard. How to correct this?

The reason are non-uniform face orientations of the shell elements on the interface between the volumes. The surface mesh orientations have to be fixed in ICEM CFD as follows:

Edit mesh > re-orient mesh > re-orient consistent

A reference element must be selected and the function then tries to align all other shell element orientations with that one. Since there's not always a unique solution the orientations on the interface should be checked and fixed by re-orient consistent again, if needed.

Hint: Visualization of the surface element orientations is available via the model tree: right click on mesh>shells > select face normals /orientations showing colors
