Underground High Current River SIM - W.I.P

[Nil]

Hello All,

Started messing with PHX FD some 2 weeks ago and i have this sim for a scene of a movie Im making...CC welcomed please .

Just used Wave force to simulate the waves. Tech detail are on the video itself.

I think it looks slightly off-scale - the water splashes around a little bit too much and is kind of "springy". Maybe it's a matter of running the simulation longer... An underground river would have already found a "steady" streaming state without this much sloshing around.

Best regards,
Vlado

the reason is the wave force, perhaps it's a desired effect, otherwise the wave force just must be not added

Thank you both for your remarks, and yes while Id like for it to be "high current", I also felt it splashed a little to much, I was actually trying to do the river simulation tutorial (from PHX 2.2 I think) but I couldn't get a similar look with PHX FD 3, and while that tutorial is nice I'd like for the water to have a lot more force than the one in the tutorial.

I was also looking for a tutorial on how to connect 2 or more grids using the cascade simulator (I had velocity channel on just like the help pages say)...because my riverbed is not on the "same plane"...it starts a bit high up and so I wanted to have a smaller GRID "delivering" the sim to a MAIN bigger one but i couldnt understand how to do that...any help would be greatly appreciated.

Ivaylo, is there another way to make river flowing WITHOUT the wave force or emitter planes like the one from the PHX 2.2 tute? the reason i ask is because whenever i try to set the ID's to these emitting polys PHX will start flowing but then it will sometimes go thru the riverbed and not collide with it i dunno why...

just make the entire simulator inclined, the gravity will do the job.

Oh..ok..man is it that easy?

Better Water Simulation

Thank you Vlado and Ivaylo for your suggestions...its now much better indeed

[vlado]

Yup that's more like it

Best regards,

yes, the dynamics looks correct now, but better use vmeo, it allows to download the original video, that is not smashed by the streaming compression
