If you have no idea about the CO2 timescale then try to estimate it using a simplified analytical approach. Otherwise do a transient simulation and get it to work out the timescales but you may have to wait for weeks for it to finish.

Hi Glenn
The simulation is of a person breathing out a tracer (0.01kgs^-1) within a room (46m^3). Running transient isn't really an option because I don't have much time. Could you point me in the direction of calculating how long it might take for equilibrium via analytical methods or otherwise please?
