### Parameter values for YouTube simulations ###

Created by **Nils Berglund** and optimized by **Marco Mancini**
|

C code for videos on YouTube Channel https://www.youtube.com/c/NilsBerglund
|

Below are parameter values used for different simulations, as well as initial conditions used in
|
||||
function animation. Some simulations use variants of the published code. The list is going to be

||||
updated gradually.
