MFEM Workshop 2024 | Platypus for MFEM Problem Set-Up and Assembly in the MOOSE Framework

The MFEM (Modular Finite Element Methods) project provides high-order mathematical calculations for large-scale scientific simulations. MFEM’s discretization algorithms enable high-performance computing systems to run these simulations more efficiently. The open-source project led by LLNL now has a global user community. Held on October 22-24, 2024, the fourth annual MFEM community workshop brought together users and developers for a review of software features and the development roadmap, a showcase of technical talks and applications, student lightning talks, an interactive Q&A session, and a visualization contest.

Alexander Blair of the UK Atomic Energy Authority presented “Platypus: An Open-Source Application for MFEM Problem Set-Up and Assembly in the MOOSE Framework.” The large-scale open-source finite element simulation framework MOOSE has built an extensive user community around its capabilities in solving large-scale FE problems across a wide range of physics domains whilst maintaining a simple interface for users. However, it currently lacks support for problem set-up and solution on GPU architectures, due in part to its default finite element library backend libMesh, restricting the range of facilities that it may effectively leverage. Here we present Platypus, an open-source MOOSE application under development for the massively parallel multiphysics simulations of finite element problems using the MFEM finite element library, supporting problem assembly and solves on both CPU and GPU architectures. We shall show some initial results on simple thermal and electromagnetic test problems and outline our development plans for supporting upcoming experiments at UKAEA at the HIVE and CHIMERA facilities.
