How do I generate the stiffnex, mass and damping matrix put of my model?

Insert below line in Case control.

EXTSEOUT(ASMBULK EXTID=100 DMIGPCH)

This will generate a PCH file which will contain the K,M Matrices that you need. Remove any output requests like DISP,STRESS, etc to avoid making PCH big with unnecessary outputs.
