I need to do some low level changes to Houdini's finite element solver for a project I am working on. So I need to get at the source code for the finite element solver DOP, in particular the source code or functions where the stiffness matrix is assembled and inverted. So far I have not been able to find the correct directory but it must happen in there somewhere. Could anyone point me to the correct path in the Houdini directories ? Any help would be greatly appreciated
