Hi guys

I’m new to flow simulation & would like to ask couple of questions:

• I understood that you can’t do gas particle analysis, why is that?
• I’m trying to simulate a co2 bubbler in an open space (just a room), don’t really know what should be my boundary condition (should I set up it as a mixture of air & co2)
• I would like to simulate the co2 particle flow, is there any way to do that? 

Thanks guys

Appreciate the help
