MFEM is a modular parallel C++ library for finite element methods. Its goal is
to enable the research and development of scalable finite element discretization
and solver algorithms through general finite element abstractions, accurate and
flexible visualization, and tight integration with the hypre library.

* For building instructions, see the file INSTALL, or type "make help".

* Copyright and licensing information can be found in the file COPYRIGHT.

* The best starting point for new users interested in MFEM's features is the
  interactive documentation in examples/README.html.

* Developers interested in contributing to the library, should read the
  instructions and documentation in the CONTRIBUTING.md file.

Conceptually, MFEM can be viewed as a finite element toolbox that provides the
building blocks for developing finite element algorithms in a manner similar to
that of MATLAB for linear algebra methods. In particular, MFEM provides support
for arbitrary high-order H1-conforming, discontinuous (L2), H(div)-conforming,
H(curl)-conforming and NURBS finite element spaces in 2D and 3D, as well as many
bilinear, linear and nonlinear forms defined on them. It enables the quick
prototyping of various finite element discretizations, including Galerkin
methods, mixed finite elements, Discontinuous Galerkin (DG), isogeometric
analysis, hybridization and Discontinuous Petrov-Galerkin (DPG) approaches.

MFEM includes classes for dealing with a wide range of mesh types: triangular,
quadrilateral, tetrahedral and hexahedral, as well as surface and topologically
periodical meshes. It has general support for mesh refinement, including local
conforming and non-conforming (AMR) adaptive refinement. Arbitrary element
transformations, allowing for high-order mesh elements with curved boundaries,
are also supported.

MFEM is commonly used as a "finite element to linear algebra translator", since
it can take a problem described in terms of finite element-type objects, and
produce the corresponding linear algebra vectors and sparse matrices. In order
to facilitate this, MFEM uses compressed sparse row (CSR) sparse matrix storage
and includes simple smoothers and Krylov solvers, such as PCG, MINRES and GMRES,
as well as support for sequential sparse direct solvers from the SuiteSparse
library. Nonlinear solvers (the Newton method), eigensolvers (LOBPCG), and
several explicit and implicit Runge-Kutta time integrators are also available.

MFEM supports MPI-based parallelism throughout the library, and can readily be
used as a scalable unstructured finite element problem generator. MFEM-based
applications require minimal changes to transition from a serial to a
high-performing parallel version of the code, where they can take advantage of
the integrated scalable linear solvers from the hypre library. Comprehensive
support for other external packages, e.g. PETSc and SUNDIALS is also included,
giving access to many additional linear and nonlinear solvers, preconditioners,
time integrators, etc.

For examples of using MFEM, see the examples/ and miniapps/ directories, as well
as the OpenGL visualization tool GLVis which is available at http://glvis.org.
