The LLNL-led MFEM (Modular Finite Element Methods) project provides high-order mathematical calculations for large-scale scientific simulations. The project’s first community workshop was held virtually on October 20, 2021, with participants around the world. Learn more about MFEM at [ Ссылка ].

Jan Nikl outlined how his team at the ELI Beamlines Centre uses MFEM for laser plasma modeling. Lasers have found their application in many scientific disciplines, where generation of plasma, the fourth state of matter, holds great potential for the future. A detailed description of laser produced plasmas is then essential for many applications, like (pre)pulses of ultra-intense lasers and ion acceleration beamlines, laboratory astrophysics, inertial confinement fusion, and many others. All of the mentioned are investigated at ELI Beamlines in the Czech Republic, a European laser facility aiming to operate the most intense laser system in the world. In this context, Nikl described the numerical construction based on the finite element method. This effort concentrates mainly on the Lagrangian hydrodynamics and Vlasov–Fokker–Planck–Maxwell kinetic description of plasma, utilizing the MFEM library for its flexibility and scalability.
