FF3D(1) A general PDE solver driven by a user friendly language FF3D(1)
NAME
ff3d - FreeFEM3D is a general PDE solver
SYNOPSIS
ff3d [-v|-h|-H]
ff3d [-nw][-V verbosity_level][filename]
DESCRIPTION
This manual page documents, briefly, the ff3d command.
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, flu-
ids (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 sup-
ported. 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 implemented).
OPTIONS
-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 exit.
-V verbosity_level, --verbosity verbosity_level
Set level of verbosity. The default number for this option is:
3
Changes ff3d level of verbosity. Bigger values will make ff3d give more and more informations.
