there was a foamdensity attribute which flipsolver outputs by default in pre 17 versions.
i looked into the solver, the counstruction for the attribute is still there.

the solver created a scalarfield named “FoamDensity”, calculating the mentioned attribute through “gas particle count”, and projected it back to geometry through “gas linear combination”. but it never outputs the foamdensity attribute.


i'm not very comfortable in the microsolver level , please let me know why is it not outputing the attribute, is it a BUG?, how can i get the attribute correctly ?

HELP, THANKS !
