Rain simulation

[mariuszhermansdorfer]

I’d like to ask whether it’s possible to use this library for surface water flow simulations similar to how rainwater would flow on a terrain?

[janbender]

Yes, that would be possible.

Thanks @janbender. Could you please point me in the right direction? A relevant function or a code snippet doing something similar would be great!

[janbender]

I would need some more info. There are several examples which show the fluid flowing on top of a boundary geometry. Do you want to emit the rain drops somehow?

[mariuszhermansdorfer]

I'd have a triangulated mesh representing a terrain and would like to simulate a uniform rain event over the entire domain. Each cell would receive the same amount of water over a specified period. Ideally, I'd like to vary the rain intensity over time (start with less, increase the amount at peak, and taper off towards the end).

I think the best way to perform such a simulation is to implement a new rain emitter with the desired properties. Take a look at the already implemented emitter and modify it.
