Summary:
Unrealistic internal forces estimated from IVD with multiple constrainst
Detailed description
Apoorva's pushup model with constrained hands and feet was generating huge moments at the shoulders and hips to hold a static posture. Moonki also seemed to have similar problems. This may be that constraints are satisfied to within tolerance (of project) but the reaction load is huge. This seems to happen when both ends of a model are constrained. This maybe resolved by an assembly analysis.
