Rheolef: a finite element environment

i.e. C++ classes and unix commands

Keywords: finite elements, numerical simulation, partial derivative equations,

C++, meshes, graphics

Version: 4.74

Rheolef is a computer environment that serves as a convenient laboratory for computations involving finite element-like methods. It provides a set of unix commands and C++ algorithms and containers.

Containers covers first the classic graph data structure for sparse matrix formats and finite element meshes.

An higher level of abstraction is provided by containers related to approximate finite element spaces, discrete fields and bilinear forms.

Current applications cover

- Poisson problems in 1D 2D and 3D with P1 or P2 elements

- Stokes problems in 2D and 3D, with P2-P1 or P1 bubble-P1 elements

- linear elasticity in 2D and 3D, with P1 and P2 elements,

including the incompressible and nearly incompressible elasticity

- [NEW] characteristic method for convection-difusion, time-dependent problems

[NEW] and Navier-Stokes equations.

- auto-adaptive mesh based for 2D problems

- axisymetric problems

- multi-regions and non-constant coefficients

Input and Output in various file format for meshes generators and numerical data visualization systems (vtk, plotmtv, gnuplot).

Both reference manual and users guide are available.
