A compiler for multilinear forms by generating code
FFC works as a compiler for multilinear forms by generating code (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.
NOTE: This package is not a generic python3 package. It is an integral part of the FEniCS project and exists only as a prerequisit for the dolfin package in the science repository. This package must not be pushed to devel:languages:python.

- update to version 2019.1.0 * Support NodalEnrichedElement, see demo/NodalMini.ufl - update to version 2018.1.0 * Remove python2 support. - update to version 2017.2.0 * Some fixes for ufc::eval for esoteric element combinations * Reimplement code generation for all ufc classes with new class ufc::coordinate_mapping which can map between coordinates, compute jacobians, etc. for a coordinate mapping parameterized by a specific finite element. * New functions in ufc::finite_element: - evaluate_reference_basis - evaluate_reference_basis_derivatives - transform_reference_basis_derivatives - tabulate_reference_dof_coordinates * New functions in ufc::dofmap: - num_global_support_dofs - num_element_support_dofs * Improved docstrings for parts of ufc.h * FFC now accepts Q and DQ finite element families defined on quadrilaterals and hexahedrons * Some fixes for ufc_geometry.h for quadrilateral and hexahedron cells - update to version 2017.1.0 * Change PyPI package name to fenics-ffc. * Let ffc -O parameter take an optional integer level like -O2 * Implement blockwise optimizations in uflacs code generation * Expose uflacs optimization parameters through parameter system - Drop obsolete python3-fixes.patch - Remove python3-devel build dependency, package is noarch. - added python3-fixes.patch for correct form compilation - update to version 2016.2.0 [2016-11-30] * Jit compiler now compiles elements separately from forms to avoid duplicate work * Add parameter max_signature_length to optionally shorten signatures in the jit cache * Move uflacs module into ffc.uflacs * Remove installation of pkg-config and CMake files (UFC path and compiler flags are available from ffc module) * Add dependency on dijitso and remove dependency on instant * Add experimental Bitbucket pipelines * Tidy the repo after UFC and UFLACS merge, and general spring cleanup. This includes removal of instructions how to merge two repos, commit hash c8389032268041fe94682790cb773663bdf27286. 2016.1.0 [2016-06-23] * Add function get_ufc_include to get path to ufc.h * Merge UFLACS into FFC * Generalize ufc interface to non-affine parameterized coordinates * Add ufc::coordinate_mapping class * Make ufc interface depend on C++11 features requiring gcc version >= 4.8 * Add function ufc_signature() to the form compiler interface * Add function git_commit_hash() - package migrated to python3 - update to version 1.6.0 [2015-07-28] * Rename and modify a number of UFC interface functions. See docstrings in ufc.h for details. * Bump required SWIG version to 3.0.3 * Disable dual basis (tabulate_coordinates and evaluate_dofs) for enriched elements until correct implementation is brought up - require swig version 3.0.3 and above - update to version 1.5.0 * Remove FErari support * Add support for new integral type custom_integral * Support for new form compiler backend "uflacs", downloaded separately - Add Requires: python-uflacs to install the new compiler system - update to version 1.4.0 * Add support for integrals that know which coefficients they use * Many bug fixes for facet integrals over manifolds * Merge UFC into FFC; ChangeLog for UFC appended below * Various updates mirroring UFL changes * Experimental: New custom integral with user defined quadrature points - Create new subpackages python-ufc and ufc-devel due to upstream merge of ufc into FFC - Added a patch to correct pkgconfig installation path ffc-pkgconfig-path-ufc-1.patch - Build of ufc requires swig - Add Requires: python-ufc to install subpackage - update to version 1.3.0 changelog available only in upstream git repository - update to version 1.2.0 * New feature: Add basic support for point integrals on vertices * New feature: Add general support for m-dimensional cells in n-dimensional space (n >= m, n, m = 1, 2, 3) - update to version 1.1.0 * Fix bug for Conditionals related to DG constant Coefficients. * Fix bug for Conditionals, precedence rules for And and Or. * Changed data structure from list to deque when pop(0) operation is needed, speeding up split_expression operation considerable * Other minor fixes - Requires python(abi) on recent products - first package
