| Abstract: | This paper presents Multi-Correction CDS scheme of only computingdominant eigensystem one time in several integration steps.This schemehas important meaning for saving computation amount of CDS method.Itsuits especially for carrying on parallel computing on pipeline computer.For this scheme,the paper discusses the stability,local truncation error,convergence and convergence order,gives a control method for convergence,discusses computation methods for dominant eigensystem and relates parallelcomputing process for this scheme. |
