Hello everyone, I am modelling a simple frame in Abaqus. I want to see the stiffness matrix for that frame. I modified my .inp file and then got the mass and stiffness matrix in .mtx file format. Now I'm not able to understand how to read this file. I am considering a beam element. I am attaching my frame model and .mtx file format. Please guide me on how to read this file. I also modelled the same in Matlab, and the results do not match with Abaqus. For that, I want to see the stiffness matrix calculated by Abaqus.

Thanks
