     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'.
