    Hello WMP3022, As isolation cushion is a proprietary item as you said, could you get Force/Displacement curves from the supplier/manufacturer for it? Then you can use a 6 DOF beam material (Beam element) with curves representing stiffness in all 6DOFs. This will let you evaluate your structure...
