This is database for Finite Element System. It is tailored to keep data for multi-physic problem with arbitrary level of approximation and different levels of mesh refinements.
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]
Cross platform electromagnetics finite element analysis code, with very tight integration with Matlab/Octave.
xfemm is a refactoring of the core algorithms of the popular Windows-only FEMM (Finite Element Method Magnetics, www.femm.info) to use only the standard template library and therefore be cross-platform.
The finite element method (FEM) package SyFi is a C++ library built on top of the symbolic math library GiNaC. The name SyFi stands for Symbolic Finite Elements. The package provides polygonal domains, polynomial spaces, and degrees of freedom as symbolic expressions that are easily manipulated.
... [More] This makes it easy to define finite elements and variational forms. These elements and forms are then used to generate efficient C++ code.
SyFi is a component of the FEniCS project, see http://www.fenicsproject.org. [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]
The Unified Form Language (UFL) is a domain specific language for declaration of finite element discretizations of variational forms. More precisely, it defines a flexible interface for choosing finite element spaces and defining expressions for weak forms in a notation close to mathematical notation.
