MFEM is a lightweight, modular C++ library for finite element discretization of PDEs, supporting arbitrary high-order element spaces, adaptive mesh refinement, and MPI/GPU-parallel scalable solvers. It serves as a finite element toolbox for research and application development, scaling from laptops to supercomputers.

Use cases

• solve partial differential equations with finite elements
• high-order finite element discretization in C++
• adaptive mesh refinement for PDE simulations
• parallel finite element solver for supercomputers
• isogeometric analysis with NURBS
• prototype discontinuous Galerkin methods
• GPU-accelerated finite element computation
• electromagnetics or fluid dynamics simulation code

When to choose

• you need scalable, high-performance FEM on CPUs, MPI clusters, or GPUs
• you want flexible high-order spaces (H1, H(div), H(curl), L2, NURBS) and many discretization methods
• you need adaptive mesh refinement and a wide range of mesh types in 2D/3D

When to avoid

• you need a turnkey GUI application rather than a C++ library
• your problem is not suited to finite element discretization (e.g., simple data analysis)
• you need a high-level scripting-only workflow without C++ development
