Do you mean those elements at the top/bottom (defining +/- Y to be top/bottom) group of elements on the left side being slightly skewed? If so I run into this quite a bit with cylinders and cylindrical type of bodies. The CAD that created has clocked the top/bottom edges relative to the other edges, so the elements are skewed as they follow the same clocking. If the effect is not too bad on the element shape we can just ignore it. If not we can often 'repair' the edges by splitting the geometry in some manner. In Mechanical there is the Virtual Topology feature which can split an edge. You can try that and see if the resulting split edges lose that clocking and the elements end up with no skewness.nMikenn
