DOLFIN
Finite Element Computing

DOLFIN is a directory of Python scripts which are used with the DOLFIN program in order to set up and solve problems described by differential equations and discretized using the finite element method.

The DOLFIN library combines a high level of expressiveness with efficient computation. Finite element variational forms may be expressed in near mathematical notation, from which low level code is generated automatically. Object-oriented interfaces are provided in the form of a C++ library and a Python module.
