Abstract : In a previous paper, we introduced a coordinate-splitting (CS) form of the equations of motion for multibody systems which together with a modified nonlinear iteration (CM), is particularly effective in the solution of certain nonlinear highly oscillatory systems. In this paper, we examine the convergence of the CS and CM iterations and explain the improved convergence of the CM iteration. An example is given from flexible body simulation which illustrates the convergence results and the class of problems for which the CM iteration is most effective.
