Hello to all,

Please see attached a scheme of my comp. domain. It consists on a straight channel with small holes in the bottom surface.
Air enters from the left to the right. In the bottom wall, O2 from the air is consumed and water is produced.

I want to write a udf in which the water produced in the bottom wall enters the channel by the nearest hole, in the liquid form.

I already manage to calculate the molar flux of water (mol/m2/s) in each cell of the bottom wall. Now I want to sum all water fluxes of the cells near each all and calculated the water inlet velocity in the wall as function of the total water flux.

Any ideas on how to do this?
I have been thinking about it for a while but i really don't know how to do it...

Regards,
Rui
