FreeFEM3D (aka ff3d) is a 3D solver of partial differential
equations (PDE). It is a member of the familly of the freefem
programs (see http://www.freefem.org).
ff3d, as well as its cousins, is a PDE solver driven by a
user-friendly language. It solves many kind of problems such as
elasticity, fluids (Stokes and Navier-Stokes) and a lot more. The
user has to enter the equation associated with the problem, giving
either the PDE in strong formulation or weak (variational)
ff3d can use either the Finite Elements method (the mesh of the
geometry being provided by the user) or a Fictitious Domain like
approach where the geometry is described using Constructive Solid
Geometry (CSG). This description is done using the POV-Ray language
but others such as VRML could be added.
The processing of the results is left to the user. One can use
various graphic tools: output in the MEdit mesh format or VTK are
supported. The implementation of a VTK base visualization module is
The goal of ff3d is to provide a good teaching tool and a research
toolbox (the code is written in C++ and its design is such that new
methods can be easily implemented).
