Why??? Any idea on how to mesh this thing??? Waiting for reply..

Remember that the divisions' numbers must be equal. Then mesh the face through face meshing. If you did not succeed, send the file to me, maybe I can fix it for you.(E-mail: keshavarzian.mohsen@gmail.com) Regards.

 August 31, 2008, 10:08 Re: Meshing on simple geometry #5 MK Guest   Posts: n/a I meant some type of quad meshing. You should make corresponding meshes (edge meshes) on corresponding parts of cylinder and peripheral square. IIn this way, meshes near the cylinder will be so fine and as we get farther, meshes become larger. I hope you get the point.
