Summary0003694: snappyHexMesh ver 8 breaks my Geometry
DescriptionProblem: Meshing with snappyHexMesh ver 8 cuts off the inlet patch and a portion of the inlet pipe of this geometry and eventually removes them. This happens during the castellation stage itself.

snappyHexMesh ver 7 runs fine on the same geometry with the same settings.
Steps To ReproducePlease unpack and run the ./Allrun.sh on the attached case using OpenFOAM versions 7 and 8.
Additional InformationPlease see the attached pictures.
TagsNo tags attached.

Have you tried different settings? Different levels of refinement in the inlet pipe for example?

Thanks for your kind reply. I first tried with different volume refinement settings on the top pipe, that didn't work. Then changed the max. surface refinement to one more level and that did the trick:

refinementSurfaces
{
    MixingTank
    {
    level (1 2);
    }
}

Perhaps the new version is more sensitive to this aspect. This results in a few more cells but I'm fine with it. I don't think we need to look at the issue any further, so you may please close the thread.
