Liquids/Fluids/Reaction Diffusion

Hello community,

I'm looking for references to simulate fluid systems ins Grasshopper. More precisely I want to simulate the behavior of a substance (real or pseudo-physical) which collides with obstacles or multiple substances behaving in a reaction-diffusion manner. I thought posting it in the Kangaroo section would make sense though. However, I couldn't find anything useful beyond that post.

Any help would be highly appreciated.

Creative Regards,

Patrick
