FDTD & TLM software ToyFDTD is a 3D FDTD program as the first code in the ToyBoxFDTD series of 3D FDTD codes. The ToyFDTD pages were so popular they have branched off to a site maintained by Laurie Miller.
WinBoB is a Windows 95/98/NT program for viewing BoB files. It allows you to load any regular BoB file (or multiple files) and dynamically select which 2D slice of that data you want displayed.
PNMA is a flexible image format comparable to the PNM image format with an alpha channel and layering capabilities. This format facilitates editing of 3D voxel data sets.
ToyTLM is a 3D TLM program as the first code in the ToyBoxTLM series of 3D TLM codes.
PulseTLM is a more full-featured 3D TLM program with an input language that allows a wide variety of EM systems to be solved. PulseTLM allows a variety of input (ex, ey, ez, hx, hy, hz) crossed with (impulse, sin, exp) sourcing and output display (ex, ey, ez, hx, hy, hz, |e|, |h|) crossed with (viz, BoB, pnm, dat, grace, binary) options. This is currently in alpha stage, however has passed several canonical tests. This is the simulation engine where the ideas, algorithms and coding strategies tested in the Toy and ToyPlane variants will be integrated.
