Dyna constrained

Webconstrained in solid simulations like rebar enforced concrete; c) porous media. This multi-role brought the keyword with 38 parameters and 22 manual pages. It has caused way too much confusion in our users and too many input errors. Starting from early 2024, the author started to work on a new penalty-based FSI package with a leaner code. WebLS-Dyna ignores *ELEMENT_MASS_MATRIX for rigid nodes (*MAT_20, *CONSTRAINED_NODAL_RIGID_BODY, *DEFORMABLE_TO_RIGID) This is a result of rigid bodies being implemented differently than deformable bodies. For rigid bodies, one single unique mass is associated for each body at the center of mass.
