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.
