MFEM Workshop 2022 | blastFEM: GPU-Accelerated, High-Performance, Energy-Efficient Solver

Tim Brewer, Ben Shields, Peter Vonk, Jeff Heylmun, and Barlev Raymond of Synthetik Applied Technologies presented "blastFEM: A GPU-Accelerated, Very High-Performance and Energy-Efficient Solver for Highly Compressible Flows." Highly compressible multiphase and reactive flows are important, and manifest across a myriad of practical applications: novel energy production and propulsion methods, building design, safety and energy efficiency, material discovery, and maintenance of our nuclear arsenal. There are, however, few tools available to industry capable of simulating these flows at a resolution and scale suitable make predictions of adequate detail—at least within reasonable timeframes and budgetary constraints—to inform engineers and designers. A next generation, highly efficient simulation code is needed that can deliver results within useful timeframes, with sufficient detail to be useful to support simulation-driven design, discovery, and optimization. Furthermore, the code must be designed to run on modern and emerging heterogeneous architectures, and can efficiently leverage these architectures though the use of numerical schemes designed to maximized computational efficiency.
