hey
I want to do air entrainment simulation uing 2 cylinders which needs to be submerged completely in the highly visous pool. they are situated a 100 mm below the interafce of the vicous liquid and the air. But while executing setFields, my alpha.liquid entry as internalField uniform 1 is automatically updates which was originally set to zero. Also using set fileds i should get a list of non uniform entries but that is absent. I dont know why this is happening.

Please looking forward for any help.
