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'.
