 pdnMesh: A finite element program
=================================

Copyright (C) 2001-2005 Sarod Yatawatta

pdnMesh is a program that can solve 2D potential problems (Poisson Equation) 
and eigenvalue problems (Helmholtz Equation) using the Finite Element Method. 
Common applications occur in electromagnetics, heat flow and fluid dynamics. 
It can solve problems using both Nodal Based Formulation and Edge Based 
(Vector) Formulation. 
The features of the program are as follows.
    * Automatic mesh generation according to given boundaries.
    * Adaptive and Interactive mesh refinement.
    * Problem solution using Cholesky Decomposition or Conjugate Gradient 
     Method with sparse storage.
    * Eigenvalue solution using LAPACK.
    * (Optionally) Eigenvalue solution using QR iteration with shifts.
    * Generating plots of contours, mesh and gradient on screen.
    * Generating Encapsulated Postscript plots of countours and mesh.
    * Generating a data file of the mesh to be used by other solvers.
    * Can import DXF files generated by CAD programs.
    * GUI is avaibale with glut and GTK/GTKGLExt. Needs OpenGL.

v. 1.12
date: 2005/11/15 06:48:11;  author: ade;  state: Exp;  lines: +1 -1
Mass-conversion to the USE_AUTOTOOLS New World Order.  The code present
in bsd.autotools.mk essentially makes this a no-op given that all the
old variables set a USE_AUTOTOOLS_COMPAT variable, which is parsed in
exactly the same way as USE_AUTOTOOLS itself.

Moreover, USE_AUTOTOOLS has already been extensively tested by the GNOME
team -- all GNOME 2.12.x ports use it.

Preliminary documentation can be found at:
	http://people.FreeBSD.org/~ade/autotools.txt

which is in the process of being SGMLized before introduction into the
Porters Handbook.

Light blue touch-paper.  Run.
