Cylinder mesh

I'm using explicit dynamics and have a fairly simple test set up. I have a cylindrical charge of TNT which detonates and I'm observing the stresses on a flat plate 0.5m away. I'm getting incredibly erratic stresses and I've assumed it's a result of the mesh of the cylinder. Are there any good ways to go about meshing a cylinder specifically for explicit dynamics.

Have you done a mesh refinement study?  That means reducing the element size by a constant factor several times in a row to see if the results change?  The constant factor would be between 1.3 and 2.0.
