I'm trying to simulate a supersonic shell (2D Axi).

I would like to mesh very precisely around the shock wave and my question is : Is it possible to have, let's say, 10 nodes on the right side of the edge, and only 5 on the other side ? -> http://img159.imageshack.us/img159/8...nstitre2bw.jpg

The problem is that I have several parallelograms surounding the wave ( http://img156.imageshack.us/img156/1725/refined7hz.jpg). There are all meshed with an intervall size of 0.5 but I would like to mesh the n°1 with an IZ=1 or 2.

But if I keep 0.5 on the other faces, I've got a very bad looking mesh on face1 : http://img104.imageshack.us/img104/3...stitre20il.jpg

Does anybody knows how to solve this ??

If you would like, in fact if anybody wants me to send him/her a couple of pictures which I guarantee you that are more than interesting, refering to shockwave simulation around hemispherical cylinder, I would be glad to help him/her.

It's all about meshing...
