DOLFIN is the C++ interface of the FEniCS project for the Automation of Computational Mathematical Modeling (ACMM), providing a consistent PSE (Problem Solving Environment) for solving ordinary and partial differential equations. Key features include a simple, consistent and intuitive object-oriented API; automatic and efficient evaluation of variational forms through FFC; automatic and efficient assembly of linear systems; and support for general families of finite elements. License: GNU Lesser General Public License (LGPL) Changes: With this release replaces the old Autotools build system with a new Scons-based build system. Other changes include improved interfaces for linear algebra, both in C++ and Python, now also including interfaces to Trilinos (Epetra) in addition to existing interfaces for PETSc and uBLAS. In addition, plotting has been improved, finite element solutions may be evaluated efficiently in arbitrary points (using GTS), and boundary meshes are positively oriented with respect to outward facets normals. Various minor improvements and bugfixes have also been made.
