The State of MFEM - Workshop 2022

Explore the state of MFEM (Modular Finite Element Methods) in this 16-minute conference talk from the 2022 MFEM Workshop. Dive into the project's history, growth, and key capabilities presented by principal investigator Tzanio Kolev. Learn about MFEM's high-order mathematical calculations for large-scale scientific simulations, including adaptive mesh refinement, GPU support, and FEM operator decomposition. Discover the project's evolution through source code growth, community expansion, and recent features in the v4.5 release. Examine examples, mini-apps, and applications powered by MFEM. Gain insights into the FEM operator decomposition and partial assembly techniques. Conclude with a look at the project's roadmap for the upcoming year, outlining plans for FY23.
