High performance Computations for Large Scale Simulations of Subsurface Multiphase Fluid and Heat Flow

摘要

TOUGH2 is a widely used reservoir simulator for solving subsurface flow related problems such as nuclear waste geologic isolation, environmental remediation of soil and groundwater contamina- tion, and geothermal reservoir engineering. It solves a set to coupled mass and energy balance equations using a finite volume method. This contribution presents the design and analysis of a parallel version of TOUGH2. The parallel implementation first partitions the unstructured computational domain.
