This is version 2.5.0 of the PDELab library.

PDELab is a PDE solver toolbox built on top of DUNE, the Distributed and Unified Numerics Environment.

The main intention is to provide a good set of high-level abstractions to allow for a reasonably quick development of simulation codes, while at the same time offering the flexibility to implement new numerical methods and optimize for specific simulation scenarios.

This package contains the PDELab library code. For application examples see the companion package dune-pdelab-howto.

If you have downloaded a release tarball, you can find the autogenerated Doxygen API documentation in doc/doxygen/html. Otherwise, you can build this documentation yourself by calling "make doc". Note that you need Doxygen and GraphViz available at configure time to be able to build the documentation.

If you need help, please ask on our mailinglist. Bugs can also be submitted to the PDELab bugtracker instead.

PDELab depends on the following software packages:

• DUNE core libraries (dune-common, dune-geometry, dune-grid, dune-istl, dune-localfunctions) version 2.5.0, and their respective dependencies.

• The dune-typetree library, version 2.5.0. You can obtain a source package or clone the repository.

• PDELab's compiler requirements differ slightly from the underlying DUNE libraries: We require at least GCC 4.7 in C++11 mode. PDELab should also work with very recent versions of ICC (icpc 15.0.1+) and current clang (3.4+).

The following software is optional:

• PETSc 3.3 - there is an experimental backend for PETSc vectors and matrices. See CHANGELOG.md for details. WARNING: The PETSC backend is currently broken.

• Eigen 3.1.0 - there is an experimental backend for Eigen vectors and matrices as well as some solvers. See CHANGELOG.md for details.
