I try to analyze the rain runoff on a terrain, what I do is project the raindrops on the terrain and then using Kangaroo solver to simulate the runoff path. However, it doesn’t succeed at last and the raindrops are very weird. The attached picture is what I want to simulate, the script is the script for this simulation.
Appreciate if anyone can help!! Thanks!
