[TRNSYS-users] TRNFLOW and relative humidity

[Pol Olivier]

Hello,
I am using TRNFLOW to calculate the air flow between different zones (in the case of one volume, I defined a fictive "large opening" between the lower and the upper part of the room).
As I want to calculate the relative humidity, I get the following message:
 
Small internal timesteps (<0.1% of simulation timestep) used for humidity calculations due to large coupling air flows between zones!
 
How could I reduce the calculated air flow or is it another way to solve this problem?
 
Thank you for your help,
 
Olivier.
