MFEM is a free, lightweight, scalable C++ library for finite element methods.

Features

• Arbitrary high-order finite element meshes and spaces.
• Wide variety of finite element discretization approaches.
• Conforming and nonconforming adaptive mesh refinement.
• Scalable from laptops to GPU-accelerated supercomputers.
• ... and many more.

MFEM is used in many projects, including BLAST, Cardioid, Palace, VisIt, RF-SciDAC, FASTMath, xSDK, and CEED in the Exascale Computing Project.

We host an annual workshop and FEM@LLNL seminar series series.
