How to get stiffness matrix from Abaqus using python??

mmalekan's picture

Dear All:

I want to extract stiffness matrix from my model. For this, I added these lines to my input file:

*STEP, name=exportmatrix

*MATRIX GENERATE, STIFFNESS

*MATRIX OUTPUT, STIFFNESS, FORMAT=LABELS

*END STEP

when I use Abaqus cae, this procedure works and a file containing stiffness matrix data is created. But, when I use python to run my input file, it seems that python doesn't read those line. So, here is my question: how can I get stiffness matrix using python?

Thanks in advance,

Mohammad

You can insert the lines in the inp file just using python instead of manually inputting them
