Linear-implicit time-integration schemes for error-controlled transient nonlinear magnetic field simulations. Clemens, M., Wilke, M., & Weiland, T. IEEE Transactions on Magnetics, 39(3):1175–1178, IEEE, May, 2003. doi abstract bibtex Linear-implicit time-step methods of the Rosenbrock type are proposed for the time-integration of the nonlinear differential-algebraic systems of equations that arise in transient magnetic field simulations. These methods avoid the iterative solution of the nonlinear systems due to their built-in Newton procedures. Embedded lower order schemes allow an error-controlled adaptive time stepping to take into account the dynamics of the underlying process. Numerical tests show the applicability of these methods for error-controlled adaptive time-integration of nonlinear magnetodynamic problems and the comparison to established singly diagonal implicit Runge-Kutta methods shows the benefits and possible problems of these specialized Runge-Kutta methods.
