An Integration Technique Especially Efficient in Dynamic Initialization

Abstract

The application of a simple variation of the Euler-backward integration method to dynamic initialization is discussed. The variation involves few additional computations, is easily programmed and permits the rate of damping to be selected. The technique can be substantially more strongly damping than the Euler-backward method, but at the expense of a reduced time step. The efficiency of the variation when used in dynamic initialization is confirmed by a numerical experiment.
