We present a generally applicable approach which allows to efficiently assemble equations necessary for solving a system of nonlinear partial differential equations discretized on a grid. Since the nonlinear problem is usually solved by a damped Newton algorithm the solution of a linear equation system has to be obtained at each step. Our assembly approach for these systems has been originally developed for the simulation of semiconductor devices based on the Finite Boxes discretization scheme… CONTINUE READING
