Dear Master Foamers,

Please, I need some help to understand and solve the problems with my pipe inlet mesh. First I thought that the problem was my mesh resolution in SHM, but after a long attempt of settings, I couldn't figure out what was going on even with a high-resolution SHM mesh.

I set a fixed input velocity on two inlets and the simulation runs very well in Salome's hexahedral mesh. But when I tried to run SHM mesh I got bad results on the inlet face. See attached pictures.

I also tried to change my *.stl resolution and files. But nothing happens.

My sequence:
- blockMesh
- surfaceFeatureExtract
- decomposePar
- run snappyHexMesh -parallel
- reconstructParMesh
.....

Pictures:

1- SnappyHexMesh error (Pressure)
2 - "
3 - Salome's Mesh results (Pressure)
4 - *.stl file inlet.

Thanks.
