pdnMesh

pdnMesh is an automatic mesh generator and solver for Finite Element problems. It will also do post-processing to generate contour plots and Postscript printouts. What is special about pdnMesh is that it is very non-interactive. The problem definition can be done in any form and given to pdnMesh as an input data file. The quality and the coarsity of the mesh can be controlled by giving input parameters.

Currently pdnMesh uses OpenGL/Mesa and glut for displaying the output but soon it will use GTK. Moreover the sourcecode is NOT 100% GNU complient at the moment and soon it will be.

The documentation is here.

We are hosting this project at SourceForge and you can follow this link to download the program.
It is also available at metalab linux archive.
Alternatively, you can browse the source tree here.

Here are some screenshots of pdnMesh at work.

• A Simple magnetic circuit with two iron pieces and one coil. Here's the solution and the mesh. (gzipped postscript)(data file)

• Something similar to a transformer core. The solution and the mesh. (gzipped postscript)(data file)

• A stepper motor at work. The solution and the mesh. (gzipped postscipt)(data file)

• A simple heatflow problem. The solution and the mesh. (data file)

• Some animations created with pdnMesh. A motor animation. The mesh used. An animation of the rotating magnetic field generated by the 3 phase windings of a motor.( Note: all are mpeg files )
