摘要:This paper investigated the use of a successiveover-relaxation parameter in a quarter-sweep finite differenceapproximation scheme. The performance of the developedquarter-sweep successive over-relaxation method is examined byconsidering a nonlinear partial differential equation, namely theporous medium equation. The main contribution of this paperis to present the stability, convergence and efficiency of the pro?posed method. Several initial-boundary value problems of theporous medium equation are solved to illustrate the efficiencyof the proposed method. The numerical results showed thatthe quarter-sweep successive over-relaxation method is moreefficient in reducing iterations and computational time thanthe standard and the existing numerical methods. In addition,the accuracy of the quarter-sweep successive over-relaxationmethod is comparable to the tested numerical methods.
