So if nonlinearities are approximated linearly and time steps are small, the essential step (= solving the connected matrix equation) will be of an update nature as well. So why not use an interative method[1][2] to solve the matrix inversion? Since the system will be sparse, this will probably be quite efficient. It might be necessary start from a true solution but tracking should be straightforward..
