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.
