报告摘要

Since the   non-overlapping domain decomposition methods have the advantages in the   computational and communicational costs in parallel computing, some   explicit/implicit non-overlaping domain decomposition methods have been developed   in solving time dependent PDEs. However, these methods break   the important physical law of mass conservation over the whole domain.   In this talk, I will first present our recent development and analysis   of the conservative splitting domain decomposition methods for parabolic   equations and for convection diffusion equations. I will then present   numerical simulations of the multicomponent contamination flows in porous   media by the developed methods. I will also present our results on   optimal control to the groundwater environmental pollution.
