Would like to do a substep every 2". If the rod moves 12", then 6 substeps.
No way, you'll need literally hundreds of substeps. I would step the rod every .010" or less, with no more surface penetration than .005-.010". Moving it too far means that surafces are penetrating/interfering with each other, and the nonlinear solver can't find a solution.

Hope you don't mind you computer running ANSYS for a couple of weeks ;)
