Can we get the stiffness matrix as an output of a Radioss simulation?

Hi, I am using Radioss 2022.3 and I'd like to get the stiffness matrix as additional output of the simulation. I didn't find any way to do that for the moment. Is it possible? If not, do other solutions exist to get this matrix (with other solvers maybe?)

Thank you in advance.

considering other solver, in this case OptiStruct, please refer to this discussion:

Hi,

Would you expand why you would like to output stiffness matrix?

In explicit solver, as Radioss, we are not so much considering stiffness matrix and there is no computed global stiffness matrix.
