PdnMesh(2001 August) PdnMesh Manual PdnMesh(2001 August) Version 0.1.2 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'. - 1 - Formatted: March 29, 2024 PdnMesh(2001 August) PdnMesh Manual PdnMesh(2001 August) Version 0.1.2 SEE ALSO d2m(1) pdnmesh_input(5) COPYRIGHT Copyright c) 2001 Sarod Yatawatta Permission to use, copy, modify, and distribute this software and its documentation for any purpose and without fee is hereby granted, provided that the above copyright notice appear in all copies and that both copyright notice and this permission notice appear in supporting documentation. - 2 - Formatted: March 29, 2024
