The vision of FEniCS is to set a new standard in Computational Mathematical
Modeling (CMM), which is the Automation of CMM (ACMM), towards the goals of
generality, efficiency and simplicity, concerning mathematical methodology,
implementation and application. FEniCS is organized as a collection
... [More] of sub
projects/components, including DOLFIN, FErari, FFC, FIAT, Instant, SyFi
UFC, UFL, and Viper. [Less]
DOLFIN is a C++/Python library that functions as the main user interface of FEniCS. A large part of the functionality of FEniCS is implemented as part of DOLFIN. It provides a problem solving environment for models based on partial differential equations and implements core parts of the
... [More] functionality of FEniCS, including data structures and algorithms for computational meshes and finite element assembly. To provide a simple and consistent user interface, DOLFIN wraps the functionality of other FEniCS components and external software, and handles the communication between these components. [Less]
SciTools is a Python package containing lots of useful tools for scientific
computing in Python. The package is built on top of other widely used
packages such as NumPy, SciPy, ScientificPython, Gnuplot, etc.
SciTools also comes with a plotting interface called Easyviz, which is a
unified
... [More] interface to various packages for scientific visualization and
plotting. Both curve plots and more advanced 2D/3D visualization of scalar
and vector fields are supported. The Easyviz interface was designed with
three ideas in mind: 1) a simple, Matlab-like syntax; 2) a unified interface to lots of visualization engines (backends): Gnuplot, Matplotlib, Grace, Veusz, Pmw.Blt.Graph, PyX, Matlab, VTK, VisIt, OpenDX; and 3) a minimalistic
interface which offers only basic control of plots: curves, linestyles, [Less]
Dorsal is a simple shell script that automates the process of fetching, compiling, and installing the various FEniCS projects (http://www.fenicsproject.org) and their requisite dependencies on Unix-like operating systems.
The following platforms are officially supported by Dorsal:
* Debian
... [More] GNU/Linux 6.0, Unstable
* Fedora 13, 14
* Gentoo Linux
* Mac OS X 10.6 (with MacPorts)
* openSUSE 11.3
* Red Hat Enterprise Linux 6
* Ubuntu 10.04 LTS, 10.10, 11.04
A number of other platforms are supported through user contributions. It is easy to extend support to other similar platforms. [Less]
Instant is a Python module that allows for instant inlining of C and C++ code
in Python. It is a small Python module built on top of SWIG and Distutils. Instant is used by FFC and DOLFIN for just-in-time (JIT) compilation of variational forms and expressions. It is part of the FEniCS Project (http://www.fenicsproject.org).
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
... [More] generated code is as efficient as hand-optimized code.
FFC is a component of the FEniCS project, see http://www.fenicsproject.org. [Less]
UFC (Unified Form-assembly Code) is a unified framework for finite element assembly. More precisely, it defines a fixed interface for communicating low level routines (functions) for evaluating and assembling finite element variational forms. The UFC interface consists of a single header file ufc.h
... [More] that specifies a C++ interface that must be implemented by code that complies with the UFC specification. [Less]
The FInite element Automatic Tabulator FIAT supports generation of arbitrary order instances of the Lagrange elements on lines, triangles, and tetrahedra. It is also capable of generating arbitrary order instances of Jacobi-type quadrature rules on the same element shapes. Further, H(div) and
... [More] H(curl) conforming finite element spaces such as the families of Raviart-Thomas, Brezzi-Douglas-Marini and Nedelec are supported on triangles and tetrahedra. Upcoming versions will also support Hermite and nonconforming elements. [Less]
