Exctract the global MASS and STIFNESS matrices to an ASCII file

Recommended Posts

Hi,

 

I'm wondering if there is anyone who can explain to me : How to export or extract the stiffness and the mass matrices to an ASCII file.

 

For now, I get *k.op2 and *m.op2 and I don't know how to read them or to use them to convert the matrices to an ASCII file.

 

I saw that there a pyNASTRAN package to post process those file .... It's my plan Z. I'm looking for a 'Smart' way to do it without using python or other code.

 

Thank you in advance,

 

Cheers,

In fact, pyNASTRAN is ONLY free possibility to read OP2 results file.
