ff3d - FreeFEM3D is a general PDE solver
This manual page documents, briefly, the ff3d
FreeFEM3D (aka ff3d
) is a 3D solver of partial differential equations
(PDE). It is a member of the familly of the freefem programs (see
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) formulation.
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 underway.
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
- -v, --version
- Output version of program and exit. The default mode is
`v', a simple version. The `c' mode will print copyright information and
`n' will print the full copyright notice.
- -h, --help
- Display usage information and exit.
- -H, --more-help
- Display extended usage information and Licence and
- -V verbosity_level, --verbosity
- Set level of verbosity. The default number for this
Changes ff3d level of verbosity. Bigger values will make ff3d give more and
