So the idea of this simulation is to press fit the Teflon piece into a hole in the aluminum plate.  Now I may have the simulation set up incorrectly, but I've defined a global 'No Penetration' Contact Set, set my aluminum plate as fixed geometry, set a roller/slider as the cylindrical face so that it can move along that axis, and applied an advanced fixture moving the Teflon piece downwards 5mm.  I would like to back out the force required on the face of the Teflon piece to press fit this piece into the hole.  Any suggestions to solving this problem would be great or if I'm going about it the wrong way, please let me know.
