[TRNSYS-users] TRNFLOW and relative humidity

[hotline]

Dear Olivier,
you can try to reduce your simulation timestep. If this doesn't help, feel free to send us your project files and we will have a look at them.
With kind regards

	Betreff: [TRNSYS-users] TRNFLOW and relative humidity
	
	
	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.
