reading element mass and stiffness matrices from op2 #842
Description
Hello,
I am attaching element stiffness and mass matrices, k.op2 and m.op2 files that are generated from a input deck consists of almost all element types: CROD, CBAR, CBEAM, CTRIA3, CQUAD4, CPENTA, CTETRA, CHEXA, CPYRAM.
The files are generated by OptiStruct. I tried to generate the same thing with NX Nastran but it gives me only fort.91 and fort.92 files.
During the generation, PARAM,POST,-5 command was used. I find it beneficial if reading of element matrices would be included to the pyNastran.
