Sometimes I happen to forget the derivative tab.

Thank you for the solution.

Re: [TRNSYS-users] Initial temperature of Storage Tank






Roberto,
  It depends on the model but usually, the initial temperatures are set in 
the Derivatives tab of the proforma, one temperature for each node. Also 
make sure that you correctly fill in the field on the Derivatives tab that 
usually asks about how many nodes there are in the tank.
Best,
 David

Hello all, 

I´m woirking with fluid storage tanks, for a solar heating system for 
residential buildings. My system simulates quite well, but i still have a 
small problem. How can I set the initial temperature of a storage tank? 
In my simulations it starts always at 0ºC so it doesn´t work as it should 
for the first 2-3 days. 
any help would be appreciated. 


Thank you.
