Can anyone help me in understanding the mesh pattern shown in below image. Why the element pattern is uniform? Even though the surface is uniform why the elements are having different aspect ratios at different circumferences? I have used both standard as well as curvature based mesh but im getting the same message. Also I wanted to know from which point the mesh generation will start in any analysis(part/ assembly) under SW Simulation. Please help me on the above query.

Thanks & Regards,

AMD
