How to extract the stiffness matrix and mass matrix of the element in comsol， I know that the code mphmatrix can extract the global stiffness matrix ，global mass matrix and so on. Yet i want to extract the matrix information of element，but i do not how to extract it? can comsol solve this problem. Or someone can offer me other methods, it is thanksful. If there is no other way, is it only possible to construct a shape function to perform the grouping of the element stiffness matrix.
