Pdnmesh now uses a Vector Finite Element (Edge Element) solver for Non Homogeneous Waveguide problems. Please check the CVS for more information!
The figures below are produced using the new solver.

After a long pause, I have rewritten pdnmesh from scratch. Now it uses a better triangulation routine. It is also possible to modify the mesh interactively. A new eigensolver is incorporated and it is now possible to solve problems involving homogeneous wave equation. Here are some screenshots of the work in progress. Please browse the CVS tree for more info.

pdnmesh 0.1.2 is out!.

It is much more improved than earlier versions. Now DXF files can be converted to ones for pdnMesh input, simplifying the task of problem definition. Moreover, it uses less memory than before and is much faster. Try it!.
