I supposed to separate zones into two domains as follows:

Hello,

From what I understand, you don't want water to enter is the zone 1 (air). Correct me if I am wrong? If that is the case, the patching won't serve the purpose if the whole model is a single region/zone.
Have you created 2 different regions/zones at the CAD level? If not, you can try that and assign one to water and other to air. By the way, may we know the purpose/objective of the simulation?

Thanks a lot for reply!!!
Your understanding is right. I don't water to enter in zone 1 (air).
I separated zones in setup of ansys fluent, not at the CAD level.
Actually, the objective of this simulation is to see the velocity profile in zone 1 (air) when affected by flow of water without loss of air.

Anyway, does doing at the CAD level imply that I should create zones and assign them in designmodeler??
Sorry, but I started to use ansys fluent a week ago... would you tell me precisely please..

If the air and water interact then you may find the result is that air/water finish up in places you don't want them.
