Thank you for your answer, i know that on this scale is more correct to use a molecular dinamics simulation, but i want to try first a cfd, anyway i tried to set a patch but it defines the concentration i set in the patch in every surface of my model, not just on the area i'm interested to.

Could this problem related to the dimension of the simulation?
