In Abaqus, i want to Modify Global Stiffness Matrix, using the Data From Mesh, and there by perform certain Operations on the Modified Global Stiffness Matrix. I have gone through the Option of Abaqus PDE, but instead of writing the entire Code, can't i be able to just change the those Values ( here Stiffness Matrix), perform some desired operations on it ?

Thanks in Advance, I really Appreciate your time :)
