I have 2 questions:
1. Can I use BerconMetaball to rendering PhoenixFD particles?
2. Is it possible to simulate beer with foam? With transitions beer → foam, foam → beer?
________
sorry for my English
For the first question yes, if you convert your simulation to a particle system using the PFlow operators provided.
You dont have to tho, as Phoenix has built in support for explicit rendering wich is superior to particle based rendering i’d say.

1 phoenix fd is grid based, there are no particles inside
2 currently there is no automation for foam/splashes, they have to be made with PF or scripting. definitively in the next versions embedded foam/splashes will be added.
thnaks for answers
efficient mechanism for the rendering foam closeup would be nice
