Hi

I would do exactly as the message states.

You have some highly skewed cells in an area with a small gap and you need to refine the mesh density in this area.

Usually the mesh tools have some way of coloring the skewed cells (I know gambit has) and you can in this manner locate the bad cells.

Else check the gambit manual on how to use the check mesh features.

Regards
