I have an 30 degree angled cylinder in-between two plates that I am having issue with snapping to the STL file. The STL file has a nice triangular surface generated with gmsh.

At the lower resolution mesh (larger cells) I get ok snapping.



But if I refine the mesh, some cells snap well, but the majority of them don't seem to snap at all.



Here are my snapping parameters. Any ideas?

snapControls
{
    nSmoothPatch 1;
    //nSmoothInternal $nSmoothPatch;
    tolerance 1.0;
    nSolveIter 500;
    nRelaxIter 100;
    nFeatureSnapIter 30;
    implicitFeatureSnap false;
    explicitFeatureSnap true;
    multiRegionFeatureSnap false;
}

I figured it out. I was running into the minVol limit in the meshQualityDict.cfg. Lowering this to

minVol 1e-18;

did the trick
