FFC: The FEniCS Form Compiler
FFC is a compiler for finite element variational forms. From a high-level description of the form, it generates efficient low-level C++ code that can be used to assemble the corresponding discrete operator (tensor). In particular, a bilinear form may be assembled into a matrix and a linear form may be assembled into a vector.
FFC may be used either from the command line (by invoking the ffc command) or as a Python module (import ffc).
FFC is part of the FEniCS project (http://www.fenicsproject.org) and functions as a just-in-time (JIT) compiler for DOLFIN.
