Rheolef is a programming environment that serves as a convenient
computations involving finite element methods (FEM) for solving
differential equations (PDE). Rheolef is both a C++ library and a set
commands for unix shell programming, providing algorithms and data
* Algorithms refer to the most up-to-date ones: preconditioned sparse
for linear systems, incompressible elasticity, Stokes and Navier-
characteristic method for convection dominated heat problems, etc.
nonlinear generic algorithms such as fixed point and damped Newton
* Data structures fit the standard variational formulation concept:
discrete fields, bilinear forms are C++ types for variables, that
combined in any expressions, as you write it on the paper.
Combined together, as a Lego game, these bricks allows the user to
complex nonlinear problems. The concision and readability of codes
with Rheolef is certainly a major keypoint of this environment.

* Poisson problems in dimension d=1,2,3.
* Stokes problems (d=2,3), with Taylor-Hood or stabilized P1 bubble-P1

transport, convection-difusion, and Navier-Stokes equations.
* input and output in various file format for meshes generators and
data visualization systems.
* auto-adaptive mesh algorithms.
