Leaking foam particles when animating

[veldkoning]

Yes...another beersim.
After struggling for weeks how to understand how Phoenix works, I think I have found the right settings how my liquid behaves.
But...leaking foam particles is still an issue when animating my object (mesh).
Also jumping foam particles is also an issue.
Am I doing something wrong? I need some help here.

Thks,

Did you try to make a thicker glass for the simulation ? (only for simulation)

I have tried that already, but that doesn't have any effect.
Thanks anyway Waaazoo.

Hey, would it be possible to send the scene over to Support so we can see what's going on and find you a workaround or a fix?

Thank you!

Should I send it to support@chaosgroup.com?

The files have been send to the above support email adres.
Please keep me posted.

Excellent, thank you very much!

Hey,

Thanks a lot for the scene! So I did a few tweaks to make it work.

1. I turned on the Push modifier you had and set it to 2 - this makes the glass a lot thicker, but should help eliminate the issues. Once your sim is ready you can turn that off.

2. I have added an Edit Poly modifier and welded some of the vertices as they were some open edges of the glass geo. I
n order to get correct results make sure to always use shelled and proper geometry (no open or overlapping edges, strange vertices, etc.)
You can check if there are any issues using the STL check modifier.

3. I have doubled the grid resolution.

Hope this helps!

Many thanks Georgi!
Does that also fix the 'jumping foam particles'?
Can you send your file?

Ah, I forgot to mention the foam - adjusting the Variation large option, the rising and the falling speed should help about that.
In my case I just changed the Variation large to 1 - so that the bubbles won't be so large. You can find more about these options here - https://docs.chaosgroup.com/display/...iquidFoam-Size

Thank you Georgi! I will try it out tonight.
Do you know a way inside Phoenix how to make the foam rise at the end, but also lowering the liquid from the top surface? In reality when you tap a beer you will see the fluid surface drop a little bit while the foam is rising.

Hey,

You can check a bit more on how foam, simulations and liquid particles work in Phoenix here.
