Both of these gave very different answers and does not seem to&nbsp;agree with my analytical calculations. I am sure the mesh is fine enough, finer mesh will take too long to solve. Not sure why is this happening and it would be great if someone can point out a few things that I can tweak to get better answer.<\/p>\n<p><\/p>\n<p>Thanks very much for any help!
