Hello!
Based on the damBreak interFoam example i am trying to "add water" within a specific area of my domain.
I have specified a cellZone for this purpose and used setFields to test the zone and general setup.
Now i want to add some m3 of water over time in that specific volume, evenly spread within.
Having inflow from a patch worked but is not what i want.
I am having a hard time finding out where to start with this.
I tried writing a source using fvOptions but log.interFoam tells me that "Source rainSource defined for field alpha.water but never used". I think that is because i can't manipulate alpha like that.
The amount i want to add per/s is rather small compared to cell size.

Please give some pointers on where to start with this.

EDIT:
i saw this: Setting Mass source in interFoam which seems to support that fvOptions is not implemented for alpha.* - but my question stands.
also saw this: interFoam modification for mass transfer however this is not cellZone specific.
