[snappyHexMesh] snappyHexMesh warning

ianjikar · July 14, 2018, 00:22

FOAM Warning :
From function void Foam::snappySnapDriver::calcNearestFace(Foam::labe l, const indirectPrimitivePatch&, const scalarField&, Foam::vectorField&, Foam::vectorField&, Foam::labelList&) const
in file snappyHexMeshDriver/snappySnapDriverFeature.C at line 399
Did not find surface near face centre (0.04035631 -0.001513536 0.1280411)

The same warning is repeated for many points.

Am getting the above warning. Does this warning has anything to do with mesh skewness as my mesh gives a fail mesh check for max skewness when using checkMesh.

Hi!

What is your tolerance in snap controls?
Try with something between 1.5 - 2.0.

I tried 0.5, 1, 5 and 10 for tolerance. I will try setting it between 1.5-2
