Hi all

I'm trying to mesh a "simple" bent tube using sHM. My goal is to resolve the boundary layer a bit... Therefore I tried three different approaches:

1. standard procedure: define the layers in the dict file and rund sHM at once
2. changing the bc type of inlet and outlet to empty before adding the layers
3. adding the layers using the utility refineWallLayer

Unfortunatly, none of these approaches succeeded!
In the attachment you will find the "overview" of the geometry and the results of the three approaches. The third one looks quite nice, but the checkMesh fails because of "incorrect orientation of faces" and "edges not aligned with or perpendicular to non-empty directions".
Does anyone know what I am doing wrong?
Any help and hints are very appreciated!

Thanks - Brahim.
