Super Urgent!!Please help!! modelling CO2 level in an office

celvin · January 27, 2017, 11:34

Hi,

I've been running simulation in an office space with 6 persons and 3 windows and I can only get results for temperature, velocity, etc. but I also need the spread of CO2 concentration level for my research too but I'm really really struggle to find the button to turn it on. Please help!!!!!

Try to model CO2 concentration in the inlet boundary, add new variable (e.g C1) in model (store/solved). Specify CO2 mass inlet and concentration (e.g in case of pure CO2 set C1 = 1.0, in case of C02/air mixture set C1 %CO2 in mixture). Set CO2 density as a inverse of C1 (see case tutorial for introducing contaminant in details)..
