Dear getfem++ users. I am Heungson Lee.
I am having trouble finding a way to compute local matrices of elements. To elaborate let's say I have a fem variable 'u' for a nonlinear problem which is updated every load step. With this 'u', I want to compute a local matrix of an element (for example local stiffness matrix) and get eigenvalues of this matrix. I was not able to find a way to do this. FYI, I am using the python interface. I would really appreciate it if you could give me some advice on this. Respectfully yours.
