This is a testbed for trying out code etc. Anything here is VERY experimental.
FDTD Animate$ (interactive page to animate loaded/drawn images using 2D acoustic finite difference time domain code)
$ Note: uses PyScript. PyScript downloads and runs Python code, which means Python is not required, but also means the download can take a little while (please be patient!) and it will use data on the order of tens of megabytes. PyScript is developmental and constantly changing, but this code uses a fixed version so hopefully won't break any time soon.

BAD panel 2D FDTD animations of scattering from a Binary Amplitude Diffuser (BAD)
Sonic crystal 2D FDTD animations of scattering from a sonic crystal
Volume diffuser 2D FDTD animations of scattering from a volume diffuser of cylinders
Slit diffraction 2D FDTD animations of transmission through periodically spaced slits
