This should work. Check that your locationInMesh is inside a cell and inside the part you want to keep. The minVol setting in meshQualityControls will not affect refinement. only snapping and...

Yes that can be the case. It reads a starting mesh to start refining from. Usually this comes from constant/polyMesh but it can also come from a time directory. The starting mesh consists of the...
