There is a fresh air stream with a carbon dioxide concentration of about 300 PPM. The fresh air stream is such that the air exchange rate is about 5 air changes per hour. After 1 hour of ventilation, the volume's carbon dioxide concentration is close to the concentration of the fresh air.
The nominal value for the trace substance is set to
C_nominal={1.519E-3}. This scales the residual
equations that are used by the solver to the right order of
magnitude.
