A man overboard! Un homme à lamer!

i think one meter water depth is enough for this case.

[jstrob]

Ok. I have 138cm with initial fill up at 50. So I have less than a meter. I increased the grid the grid to 65 million cel and I am resimulating with a fatter guy. It should help too.

[Ivaylo Katev]

the spf may also be important, if the distance traveled by the object is too big for one frame, it just hides below the water without transferring too much energy to the water.
i found the cube scene, look at it

[jstrob]

Great thank I will take a look at the scene!

what is raylogger.dlr? An internal tool I guess.

[Ivaylo Katev]

yes, it's an internal tool

[jstrob]

Now I am getting a bigger splash! I am just simulating the water without foam or splash right now, and just with more cell count: I am at 121 millions now, a fatter diver, and I didn't decelerate the animation this time.
I am just afraid the splash will go higher than my grid. I don't remember, can the phoenix grid change size dynamically?

[ivaylo.ivanov]

Yes, of course. From the Grid section, adaptation by Liquid/Temperature.

[Ivaylo Katev]

don't worry about the splash height, it can leave the grid, just set outside time bigger than zero. this is the life span allowed for outside simulation of the foam/splash.

[jstrob]

There are 2 Ivaylo at chaosgoroup?

Thanks to both of you!

But now I am simulating only the water. I increased the top but now my splash is making a bigger wave and the wave just got out of the box this morning... and I am at 221 972 400 cells... It seems to be able to handle it.

I will make it adaptative next time.

[Ivaylo Katev]

don't forget to enable the "maximum expansion" option, and to allow the expansion only in z direction.

[jstrob]

I was able to simulate something acceptable. I had to reduce foam and splash cause it was bringing my system to its knees. I need more ram (only 24 Gb at the moment.)

Now I have to find a way to render this. I use light cache, remove shadow and disabled scattering. Still more than 2.5 hour a frame.

On this one the foam and splashes were too grey, I corrected it. Waiting for the render.

[Ivaylo Katev]

just increase the size multiplier of the foam shader, to make the splash particles dense, you can have good looking splash even with 1M particles!

[jstrob]

I have surely gone too far with cel count. I had a lot of trouble simulating the particles and now for rendering... I now have a frame that took almost 12 hours to render!

Yes, I think 200M cells is way too much. Vlado always said 5M is good. You could have 10M.... but 200M is probably way too much

[Ivaylo Katev]

not sure that the cells count are to blame.
can you send us a single cache and the scene to try some render optimization?
