NAME
pdnmesh - A 2D finite element program

SYNOPSIS
pdnmesh [-b badness] [-s splitting priority] [-a area] [-c contour levels ] [-v ] [-nx ] [-do ] -i input file

DESCRIPTION

pdnmesh is a 2D finite element problem solver. It generates the Delaunay tringulation 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.

OUTPUT
The program will generate two Encapsulated Postscript files called mesh.eps and cont.eps of the mesh and the contour plot respectively. If a display is available, the program can also display its results on the screen.

OPTIONS
pdnmesh accepts the following options:

-h, -?
    Print the currently installed version of pdnmesh on the standard output.

-s VALUE
    Sets the splitting priority to VALUE. Triangles with higher priority are more likely to be split in later iterations.

-b VALUE
    Sets the minimum badness for a triangle to be split to VALUE. Badness is the ratio of the longest edge to the shortest edge in terms of lengths.

-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.

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

-v  Print verbose output.

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

-do Generate the data file of the mesh as 'data.in'.
