FDTD++ wiki

Welcome to the FDTD++ wiki, the instruction manual FDTD++, finite-difference time-domain (FDTD) software in C++.

The FDTD++ wiki is organized into sections below, and presented in the order that someone new to FDTD and/or FDTD++ should visit. Note that the material models and the materials database are provided on an external website, since they are not specific to FDTD++.

For discussions of FDTD++ (support, suggestions, etc.), as well as the FDTD method itself, visit the discussion forums.

If there are any features that you wish to see in future versions of FDTD++, please report them also to the discussion forums.
