Following a question on old grasshopper forum, I gave a try to the Belousov–Zhabotinsky reaction. Thanks to @Dani_Abalde. I first replicated Daniel Abalde work then applied it to a mesh. It is quite straightforward as it is a mix between reaction diffusion work and Belousov–Zhabotinsky equations (see the links).
Same mesh model but 2 numbers of itteration (1600 and 600)
Daniel González Abalde work
Equations I used
