Hi,
I use twoPhaseEulerFoam, and I need to solve my fields (Ua and Ub) only in one zone. For this I think that I should add a source term which equal to zero in the zone of resolution and like 1.e+20*Ua in the others zones. but I don't know how to do this.
I count on your help

Hi Danielle

I propose you to have a look there :

what you need is called a mask function
in this threat, we add a source term on one part of the geometrie and not on the other part. so, the mask function is one on the first part and 0 near.

I hope it will help you

Cedric
