I am trying to compute the geometric stiffness matrices of a model with distributed loading. I would like to export what is being showed in the textbook excerpt below. I am unfamiliar with how to go about exporting this matrix. I can set up the model, loading, and run a SOL101, but don't know about the output. Is this the same thing as a differential stiffness matrix? Any insight on how to go about this would be appreciated!
