Three-Dimensional Paleohydrologic Simulation using Parallel geofe on the Teragrid Resources

Abstract

Abstract—Parallel geofe, a parallel, three-dimensional finite element paleohydrologic modeling program, was developed based on the serial code, with the aim to simulate ground water flow on the Atlantic continental shelf in New England within the past two million years, and help to explain the large amount of unconventional freshwater plumes within offshore aquifer systems in the above area. We used ParMetis for mesh partitioning and Aztec to solve the sparse linear system for the modeled groundwater flow, heat transfer and solute transport processes. The resulting program demonstrates good scalability on the Teragrid systems.
