Point source in Fluent
 

Dear all,

I am trying to simulate contamiant transport (CO2) in a ventilated room(isotherm). The contaminat is added to the room as a point source by a carrier gas(N2 or He), so we can change its density (heavier or lighter than the room air). My problem is how can I add this source into the Boundary Condition in Fluent?

Thank you very much for your help in advance.

Cheers,

Shengping
