Hi everyone!

I using the VOF method to simulate water entering in a gas channel through a small pore in the bottom surface. The gas phase is dry air (0.21 O2 and 0.79 N2) and i would like to add a 02 sink in the bottom surface.

For now I consider a constant value for the sink, but in the future i will UDF to specify it.

I tried this:
First i separate the solid domain in two: Adapt -> boundary -> and I mark the cells adjacent to the bottom surface
Then i separate the marked cell from the entire domain: mesh ->separate -> cell -> and i select the marked cells

Then I add a source term (with a - signal because it is a sink): cell zone conditions -> solid:032 (the zone that i just separated) - > source terms -> O2 -> I a put the value 1e-6 kg/m-3/s-1

I did the simulation but the results are exactly the same as if i did not add any source. My source term is low and i already tried (much) larger values but the results does not changed.

Can anyone help me to with this?
