## What it is
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

## Facets
- artifact type: library
- maturity: stable
- function: simulation, math, graphics, gpu-computing, concurrency
- domain: simulation, gpu-computing
- platform: cpp, windows, cross-platform
- tags: finite-elements, fem, pde-solver, high-order, amr, hpc, mpi, isogeometric-analysis, scientific-computing, numerical-methods, algorithms, physics, high-performance-computing, linux, macos, gpu
