Prevent Penetration on Single Sheet Metal Part

Hi,

How can I prevent mitered corners of a sheet metal part from penetrating each other in a static simulation?  I tried applying a component contact and contact set, but the component contact seems to have not worked (result shows edges intersecting) and the contact set wouldn't let me select the faces of the mitered edges.  There is a .020" gap between the faces for welding, and I want to make sure the analysis knows these two faces are bonded together and cannot penetrate one another.
