摘要
以四阶抛物型方程为模型,建立了一个区域分裂并行差分格式,并对该格式进行了稳定性以及收敛性的讨论,得出:当网格比r≤0.24时,该格式稳定且收敛。最后,通过数值例子对该结果进行了验证。
The domain decomposition parallel difference scheme for forth order parabolic equation is presented and discussed the stability and convergence. The stability condition is proved to be r≤0.24. Finally, the numerical experiments is maked. Some numerical results are given.
