I am also trying to get a structured hexahedral mesh. I made some splits in CAD which result in the different bodies that you see in the pictures. This simulation also utilizes cyclic symmetry. The mesh controls I applied where the following:<\/p>\n<ul>\n<li>Multizone (Standard decomposition) with a Split Angle of 60&ordm; for Body 1<\/li>\n<li>Same as before for Body 3<\/li>\n<li>Multizone (default settings) for Body 2<\/li>\n<li>Face meshing for the bigger face of Body 1<\/li>\n<li>Hard Edge Sizing: 2 divisions on green edges<\/li>\n<li>Hard Edge Sizing: 1 division on yellow edges<\/li>\n<\/ul>\n<p>Why are the shown elements distorted and how can I avoid that? This is part of a parametric study.If possible ,a non mesh-specific solution is desirable.
