Resimulation for foam

[MANUEL_MOUSIOL]

Hi,

I am currently trying my luck to replicate the beer tutorial Tsetso made.
I was wondering if it is a good idea to simulate just the liquid first and then add the foam/bubbles with the resimulation feature, or does the foam have an impact on the liquid too so that it would be the most realistic to simulate both together. The foam takes quite a while to simulate and I already spent more than a day to get where I am...still not satisfied.
BTW, here is where I am currently (simulating liquid and foam in one go):

On another account, would it be possible to produce more of the uprising foam for the beer "crown" with an additional PHXSource that is producing foam from an elevated plane? I just tried to produce foam from with that source and a plane but nothing came out. dragged particles work fine though.


Thanks as always!

yes, you can resimulate the foam after the liquid, there is no impact on the liquid.
and you can produce additional foam, but i think it will look less realistic

Thanks for the fast answer!
I was thinking of creating a certain shape for the foam crown, you know? So if we have a certain liquid behavior that shouldnt be changed but a certain foam shape, maybe using an additional foam source would help to "sculp" a certain shape.
but for now I cant even get the foam to be created by the PHXSource. Does it need any friction to be created?

well, for certain foam shape you have to cheat of course
