Welcome to the r_fdtd wiki!

Finite Difference Time Domain (FDTD) is a way to numerically solve (among other things) the telegrapher equations for transmission lines.

This software provides a way to visualize what is happening on a specified transmission line when stimulated with a voltage source.

I'll eventually put together a "getting started guide." It may even have pictures!

For now, you'll need to install R (https://www.r-project.org/).

Download the source code. Set your working directory (file -> change dir) to the directory where you unzipped the source. Then select the source file you want to run. (file -> source R code...) I'd suggest running "simulate_t_line.R"

Another file select dialog will pop up. Go to the examples folder. Pick an example to run (like "example_line.R")

Experiment, modify, learn.
