Algebraic Multigrid Preconditioners for Scalable Simulation of Reservoir Geomechanics and Multiphase Flow

Joshua White | 18-ERD-027

Executive Summary

The goal of this project is to enable high-resolution simulation of subsurface energy applications of strategic national interest, such as unconventional oil and gas production, geothermal energy, and carbon storage. This research addresses a key numerical bottleneck that currently prevents such simulations from running efficiently on large high-performance computing platforms.
