Mesh to Shell

   I am currently learning how to use Karamba.  I am doing an example of a square plate pinned on two sides.  When I am creating the shell from the square mesh, it divides the mesh into triangles. I was wondering if there was a way to have Karamba keep the shell as a quad mesh, so that the reaction forces do not end up being asymmetric.  I have been told that quad meshes are more accurate especially when the panels are just square panels.
