Default 3 different CO2 concentrations in one room

wangy1767 is on a distinguished road
Dear all,

I want to simulate a room with 3 different initial CO2 concentrations in the top (high CO2%), middle (middle CO2%) and low (low CO2%) parts of the room, separately, using CO2 as an additional variable. There are 3 inlets of fresh air flow in the low part of the room and one outlet in the top of the room.

Hence, whether I need create a box with 3 bodies as 3 parts of the room in ICEM?
Then whether I need create 3 domains and 2 interfaces for the room in CFX-Pre?

Or could you users please give me some suggestions for the case in details?

Many thanks in advance!
