refine mesh based on skewness

Hi

I'm on simulation of an elastic square prism. Results are obtained to some time, then the solver (solids4Foam) crashes. The reason is that the highlighted cell(s) shown in the figure below becomes concave. (Note: Fluid region mesh is shown only.)
Is there any way for run-time mesh refinement according to skewness in order to figure out this difficulty?

regards
Ali
