Hello, a need to make a fluid simulation for my thesis o a site with mountains, i allready have the topography on rhino, but i don´t know how i can simulate rain and fluis going to the gravity, hope you can help!

maybe this helps: [image] Water Flow on Surface Grasshopper Is there any way to calculate the rain runoff for any given surface (imagine a simple dual pitch roof for example)? I have tested several plug-ins like Mosquito and alike. The drain directions (flow pa…

If you post geometry this will make the whole thing a lot easier. Also what exactly do you want to achieve.

Check this out. But the model must be in meters. [lit] simpledrainage_liters_m3.gh (86.1 KB)

thank you for this! may i ask how did you made the blue balls, and animate the whole thing?

Hi Daniel, I am trying to do the same but, I want to use some curves as a blockage/dam for flowing points on the mesh(flow along the curve at slope direction, after hitting), tried CurvePointCollide but it seems like curves needs to be closed polyline, anything to suggest? [image] Best

Here’s an example that adds a new collider for open curves and points [image] drainage_dams.gh (19.7 KB) drainage_dams2.gh (56.4 KB)

Thank you very much Daniel, however when I scale everything up 100 times or more then points are just passing by the curve obstacles. Could not solve it… Can you help me about it? Thanks in advance.

Hi Daniel, the simulation animation is awesome. How did you do it?

Hello, How can I access instructions on how to use this?
