Splashes threshold problem

[TSR_trix]

Hello guys,
I got relatively big simulation grid box (20*30 meters) and some big rocks falling on it.
I use temperature channel for liquids with sharpness 0.8 and static surface correction on. Total cells 70 million and cell size 0.029m.

For some reason if I enable splashes and give it low birth threshold, like 0-5, I get almost none particles.
I also try to set birth rate to 5-50, but it wont solve anything.

How could I get splashes threshold work properly?

Do you have Strong Surface Mode option on?

[Ivaylo Katev]

i suppose the static surface correction is to blame, if you start with settled water

Thanks guys, yes I have to try without SSC. I try with and without strong surface mode but it didnt make any change.

Now I have run some tests, and it seems that it doesnt matter if I switch off Static surface correction and Strong surface mode. Still I cant get threshold working.
Or at least it wont give me huge amount of splash particles.
I urgently need those particles even when my liquid simulation is OK in other parts.

if the particles are born, but are not enough in count, you can increase the birth rate. if this does not work, please send us the scene

I send you an email with the Max file. Thanks!

the birth rate has particles per-volume dimension, and your simulator is very small by volume, so i just increased it 1000 times and everything is ok.

Ah, nice one thanks! I should have noticed this via documentation, but it didnt cross to my mind.

Btw, in my case part of a bridge is falling to the sea, how deep should I have my simulation grid with liquid? For now It seems quite good with the level that I have, but to keep grid size small as possible, I use quite low sea depth with cells. But obviously I want to have real world size water splash from the falling rocks, so does it matter how much I preserve water under the falling parts?

this is up to your camera postition, if you can't seee the bottom the depth is good enough
