In the Sol 400 UG, chapter 13, it states “The current implementation is restricted to the requirement of a set of STATIC supports that constrains all six
rigid body motions only. Please note that the constraints must be only removing the rigid body motion, but not
induce any addition deformation and stress. Thus no mechanisms or symmetry boundaries are allowed.” I am not entirely sure how to create this condition. If I restrain a node it will induce stress at that point.
Is there a feature that will allow a nonlinear material analysis without any restraints? I was running the solution with inertia relief, but I had linear material properties. As soon as I introduce the nonlinear material the solution failed. I tried param,inrel,-2, but that didn’t work either.
