About rheolef

From Debian's package description

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 commands and C++ algorithms and containers.

Most basically, containers cover the classic graph data structure for sparse matrix formats and finite element meshes. At a higher level of abstraction, they can handle approximate finite element spaces, discrete fields. Flexible and powerful expressions are used to specify bilinear forms.

Current applications include:

• massively distributed memory finite element environment, based on MPI;
• elasticity, Stokes and Navier-Stokes problems in 2D and 3D;
• complex fluids applications: viscoplasticity, viscoelasticity, wall slip;
• nonlinear problems with fixed-point, Newton and continuation methods;
• high order polynomials, mixed elements and discontinuous Galerkin methods;
• auto-adaptive mesh approaches;
• axisymmetric problems;
• multi-regions and variable coefficient problems.

This package provides the rheolef commands. These support input and output in various file formats for mesh-generators and numerical data visualization systems such as paraview, and gnuplot.
