### 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.
