1) How can I output the differential stiffness matrix in MSC Nastran 2012? "PARAM,EXTOUT,DMIGPCH" can output the stiffness matrix, and is there something similar for the Differential Stiffness Matrix?

2) What document describes the formulation of the differential stiffness matrix for a CROD element? I have checked the Linear Statics User Guide, but it just goes over the beam element.

3) Is there an example of a truss buckling problem lurking somewhere? Please point me to it if you know where it is located.
