I'd like to export mass and stiffness matrices of a constrained model (e.g. MPC applied) and retain information on the ASET, i.e. the independent degrees of freedom. Is that possible somehow?
Up to now I've used to obtain the relevant matrices only under free-free conditon by using PARAM,EXTOUT,DMIGPCH
How are you defining the displacement boundary condition? If using SPC/SPC1 entries, they are turned on via an SPC case control command. Maybe that is missing?
