NAME
       pdnmesh - A 2D finite element mesh generator and	solver

SYNOPSIS
       pdnmesh [options] [-i input file]

DESCRIPTION
       pdnmesh	is a 2D	finite element problem solver. It generates the	Delau-
       nay triangulation of an input point set and afterwards, it  will	 solve
       the problem. Apart from the points, the set of edges and	the boundaries
       should be specified in the input	file.

       This is a beta release. Most of the options can now  be	changed	 using
       the  GUI.  So  do not expect the	command	line options to	work properly.
       Please report bugs to  pdnmesh-bugs@lists.sourceforge.net.

OUTPUT
       The program can generate	Encapsulated Postscript	 files	of  the	 mesh,
       contours	of potential and gradient and ASCII files of the mesh.

       In  text	 only  mode,  by default it will generate the mesh and contour
       files. If a display is available, the program can also display its  re-
       sults  on the screen. It	can display the	equipotential contours as well
       as the gradient.

OPTIONS
       pdnmesh accepts the following options:

       -h, -?  Print help.

       -V      Print the currently installed version of	pdnmesh	on  the	 stan-
	       dard output.

       -s      Uses the	sparse matrix solver instead of	the full matrix	solver
	       (for Poisson Equation only).

       -a VALUE
	       Sets the	minimum	area of	a triangle to be split	to  VALUE  The
	       area  is	taken with respect to local coordinates, NOT the input
	       coordinates. The	local coordinate system	is enclosed in a 2  by
	       2 square	centered at origin.

       -A VALUE
	       Sets  the  maximum  area	of a triangle to be split to VALUE The
	       area is taken with respect to local coordinates,	NOT the	 input
	       coordinates.  The local coordinate system is enclosed in	a 2 by
	       2 square	centered at origin.

       -c VALUE
	       Sets the	number of contour lines	drawn to VALUE an integer.

       -i FILE Reads the input file given by FILE which	should be in the  cor-
	       rect format given by pdnmesh_input(5).

       -d (contour|grad|fill)
	       By  default  displays either the	contour	plot, gradient plot or
	       colour fill.

       -e (poisson|helmholtz|helmin|helmk|helmbeta)
	       Selects the solver to use.

       poisson : Poisson Equation.

       helmholtz : Homogeneous Helmholtz Equation.

       helmin :	Inhomogeneous Helmholtz	Equation (using	edge elements).

       helmk : Find cutoff frequency given propagation constant.

       helmbeta	: Find propagation constant given cutoff frequency.

       -v      Print verbose output.

       -nx     Do not open graphical display. This is used when	the program is
	       run in text mode.
