Q: Is the stiffness matrix (hydrostatic and connector) used in MOSES a 3 X 3 matrix with coupling terms, using the assumption of small motions?
REV 5.03

A: No, this stiffness matrix is a N X N matrix where N is 6 times the number of bodies. In the frequency domain, it is assumed to be constant. In the time domain, it is computed correctly at each time step.
