TY - GEN A1 - Ebert, Falk T1 - Some new aspects of the convergence of dynamic iteration methods for coupled systems of DAEs N2 - The purpose of this paper is the analysis of dynamic iteration methods for the numerical integration of coupled systems of ODEs and DAEs. We will investigate convergence of these methods and put special emphasis on the {\sc Jacobi}- and {\sc Gauss-Seidel} methods. Furthermore, the fundamental difference in the convergence behaviour of coupled ODEs and DAEs is pointed out. This difference is used to explain why certain relaxation methods for coupled DAEs may fail. Finally, a remedy to this undesirable effect is proposed that makes use of a so-called {\em preconditioned dynamic iteration} strategy. This regularization also allows significant reduction of dynamic iteration steps.
