A multiple domain algorithm for modeling two dimensional contaminant transport flows

摘要

To efficiently simulate large scale contaminant transport flows on serial computing platforms, the authors believe that explicit finite difference formulations need to be integrated with performance-enhancing tools. Such integration will not only increase the scope of modeling across various applications but is also aimed at achieving better physical modeling of the transport. In this paper we introduce the application of a multiple domain algorithm (integrated with a finite difference formulation) to solve the two dimensional advection dispersion equation. The efficiency of the abstractions and mechanisms provided by this integration, aimed at accelerating the solution to the desired transient state, is tested. The focus is first in discussing the formulation and then testing its reliability, with and without the integration. To check the latter, we have used an analytical solution as the benchmark solution. The results indicate that the primary purpose of using a multiple domain approach is met without any loss in the accuracy of the solution.
