Rheolef is a general purpose free sofware C++ library with applications to CFD and complex fluids (viscoplasticity, viscoelasticity).

It is maintained by Pierre Saramito and others at CNRS, France and distributed under the GNU GPL. Rheolef is a very nice and capable code with state-of-the-art methods.

News in version 7.1:

- Reference manual renewed and new web site with doxygen
- Hybrid discontinuous Galerkin (HDG and HHO) methods
- User's manual introduces new examples:
  * HDG and HHO examples
  * zalesak & leveque examples: discontinuous Galerkin
  * slip boundary conditions
- Visualization:
  * branch: run animation with paraview
  * high order FEM and curved boundaries: with paraview and gmsh
- Eigen sparse solver (sequential)
- Mac-osx porting with clang
- Minor bug fixes

Main features:

- Complex fluids applications: viscoplaticity, viscoelasticity, wall slip
- Elasticity, Stokes and Navier-Stokes problems in 2D and 3D - Massively distributed memory (MPI) support
- High order polynomials, mixed elements and discontinuous Galerkin methods
- Nonlinear solvers: fixed-point, Newton and path-following methods
- Auto-adaptive mesh
- Axisymmetric problems
