refineFieldDirs tutorial produces warnings at iter6

Summary

From iter5 to iter6 the refineMesh stars complaining

Steps to reproduce

tutorials/mesh/refineMesh/refineFieldDirs

Run step by step (remove the -overwrite). Going from 5 to 6 it will complain:

cellCuts : constructor from cellCutter
--> FOAM Warning : 
    From void Foam::cellCuts::setFromCellCutter(const Foam::cellLooper &, const List<Foam::refineCell> &)
    in file meshCut/cellCuts/cellCuts.C at line 2435
    Found loop on cell 1 that resulted in an unexpected bad cut.
    Suggestions:
      - Turn on the debug switch for 'cellCuts' to get geometry files that identify this cell.
      - Also keep in mind to check the defined reference directions, as these are most likely the origin of the problem.

Switch on debug for more info

DebugSwitches
{
    cellCuts    2;
}

Environment information

  • OpenFOAM version : v2106

Possible fixes

Since topo is not very complex and the cuts are still made ok maybe it is just a geometric tolerance?
