Finite elements for partial differential equations

 Rheolef is a computer environment that serves as a convenient
 laboratory for computations in applied mathematics, 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
  - characteristic method for convection-difusion, time-dependent problems
 and Navier-Stokes equations.
  - auto-adaptive mesh based for 2D problems
  - axisymetric problems
  - multi-regions and non-constant coefficients
  - axisymetric problems
