Version 3.3.2 of MFEM, a lightweight, general, scalable C++ library for finite element methods, is now available.

The goal of MFEM is to enable high-performance scalable finite element discretization research and application development on a wide variety of platforms, ranging from laptops to exascale supercomputers.

MFEM has many features, including:

• 2D and 3D, arbitrary order H1, H(curl), H(div), L2, NURBS elements.
• Parallel version scalable to hundreds of thousands of MPI cores.
• Conforming/nonconforming adaptive mesh refinement (AMR), including anisotropic refinement, derefinement and parallel load balancing.
• Galerkin, mixed, isogeometric, discontinuous Galerkin, hybridized, and DPG discretizations.
• Support for triangular, quadrilateral, tetrahedral and hexahedral elements, including arbitrary order curvilinear meshes.
• Scalable algebraic multigrid, time integrators, and eigensolvers.
• Lightweight interactive OpenGL visualization with the MFEM-based GLVis tool.

Some of the new additions in version 3.3.2 are:

• Support for high-order mesh optimization based on the target-matrix optimization paradigm from the ETHOS project.
• Implementation of the community policies in xSDK, the Extreme-scale Scientific Software Development Kit.
• Integration with the STRUMPACK parallel sparse direct solver and preconditioner.
• Several new linear interpolators, five new examples and miniapps.
• Various memory, performance, discretization and solver improvements, including physical-to-reference space mapping capabilities.
• Continuous integration testing on Linux, Mac and Windows.

MFEM is being developed in CASC, LLNL and is freely available under LGPL 2.1.
