Sewer tsunami testing

[Jussing]

So I have this old model of the Tokyo undeground sewers.... I always wanted to fill it with water, but didn't have the tools for it until now.

Any tips for how to set up friction for the floor? In this version, I cheated by making an initial fillup of a few inches, which makes the tsunami water stop and splash, tumbling over itself in a dramatic way, rather than flattening out real quick.

Hey, this looks like a good way around it. You can make the liquid sticky to the geometry by enabling wetting+sticky, and having a bit of viscosity, but viscosity is not okay for this kind of simulations...

Cheers!

Thanks, Svetlin! Are you still planning a friction-per-object option?

It would be good to have...
