FFC

FFC can be used as a form evaluation system for DOLFIN but can also be used to compile forms for other systems as well.

FFC works as a compiler for multilinear forms by generating code (C or C++) for the evaluation of a multilinear form given in mathematical notation.

This new approach to form evaluation makes it possible to combine generality with efficiency; the form can be given in mathematical notation and the generated code is as efficient as hand-optimized code.

What is new in this release:

• This is a bug fix release that fixes a small number of bugs in preparation for the upcoming release of FFC 1.0.0.

What is new in version 0.7.0:

• Move contents of TODO to: https://blueprints.launchpad.net/ffc
• Support for restriction of finite elements to only consider facet dofs
• Use quadrature_order from metadata when integrating terms using tensor representation
• Use loop to reset the entries of the local element tensor
• Added new symbolic classes for quadrature optimisation (speed up compilation)
• Added demos
• Tabulate the coordinates of the integration points in the tabulate_tensor() function
• Change command line option '-f split_implementation' -> '-f split'
• Renaming of files and restructuring of the compiler directory
• Added option -q rule (--quadrature-rule rule) to specify which rule to use for integration of a given integral. (Can also bet set through the metadata through "quadrature_rule"). No rules have yet been implemented, so default is the FIAT rule.
• Remove support for old style .form files/format
