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, 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 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.
