Distibution: sources and binaries as debian packages
Keywords: finite elements, numerical simulation, partial derivative
C++, meshes, graphics
* nonlinear solvers improved (see p-laplace example)
equations on a surface: implements three diferent FEM methods
* improves the high order Pk Lagrange interpolation implementation
ports on intel c++ 12.0 and gnu c++ 4.7 new compiler versions
Previous features:
Rheolef is a programming environment that serves as a convenient
laboratory for
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-
Stokes flows,
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
can be
combined in any expressions, as you write it on the paper.
Combined together, as a Lego game, these bricks allows the user to
solve most
complex nonlinear problems. The concision and readability of codes
with Rheolef is certainly a major keypoint of this environment.
Main features
* [NEW] Massively distributed memory finite element environment, based
on MPI.
[NEW] High-order polynomial approximation.
* Poisson problems in dimension d=1,2,3.
Stokes problems (d=2,3), with Taylor-Hood or stabilized P1 bubble-P1
* linear elasticity (d=1,2,3), including the incompressible case.
characteristic method for time-dependent problems:
transport, convection-difusion, and Navier-Stokes equations.
* input and output in various file format for meshes generators and
data visualization systems.
Advanced features
auto-adaptive mesh algorithms.
* axisymetric problems.
nonlinear problems with either fixed-point algorithms or a provided
damped Newton solver.
* 3d stereo visualization
Both reference manual and users guide are available.
