Bar Impacting a Rigid Wall

A deformable copper bar impacts a rigid wall at high speed. Differences in contact modelling via *RIGIDWALL_PLANAR and *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE can be studied. Solutions with constant stress solid (elform 1), fully integrated S/R solid (elforms 1, -1, -2), 1 point tetrahedron (elform 10), 1 point nodal pressure tetrahedron (elform 13) and 1 point ALE (elform 5) can be studied.
