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.
