Hello, I'm trying to simulate a supersonic shell (Mach 2.4) and its sonic boom, 1 meter away.

My mesh is a quand mesh (structured) with an interval size=0.2mm : http://img87.imageshack.us/img87/3509/sanstitre5rk.jpg

Is a structured (quad) mesh appropriate to this study? Or should I use an unstructured one (tri) ?

Thanks !

Cyril
