Dear All:
I want to extract stiffness matrix from my model using python command.
I know how to extract stiffness matrix using input file commands, but the problem is when I want o run input file using python, pthon skip those lines correspond to extracting stiffness matrix. I dont know why. Because of this, I want to include some command inside my python code in order to extract stiffness matrix from abaqus model. But, I dont know how o do this. Could you please help me?
Thanks,
Malekan
I dont understand. Global stiffness matrix or local tangent stiffness matrix?

Global stiffness matrix. I want to pass this matrix to another program.
Malekan
I am not sure if you can do that. Let us know if you figure out a way...

Actually, I want to write the global stiffness matrix to a file that will read by another program. I know how to write stiffness matrix to file using input file command, but my problem is when I want use python. Do you know any command to do that?
Malekan
Can you let me know how you write the stiffness matrix to file using input file command?

I added these lines before step definition in input file:
*STEP, name=exportmatrix
*MATRIX GENERATE, STIFFNESS
*MATRIX OUTPUT, STIFFNESS, FORMAT=LABELS
*END STEP
