How to check for skewed elements in surface mesh
In the short but very informative post regarding selection of turbulence model, http://www.symscape.com/node/1457#comment-1881 there is warning against skewed mesh elements.
How shall I check for skewness? I have plotted E ratio but I do not know the recommended range. This is also only for surface mesh, not volume mesh where I guess skewness is likely important?.
