[TRNSYS-users] digging into trnflow convergence problems

[frodriguezpc at labein.es]

It crashes even at n=7 timestep... I am pretty sure it has to do with this 
temparature thing. A check to my lst file shows this clear pattern with 
lack of convergence in al the external temperature peaks, so I turned off 
cooling and the result is I get convergence thanks to interior 
temperatures going above exterior at most of the previous conflict 
timesteps... still there are a couple times of year where I still get 
higher ext. temps, and convergence problems show

You could try even smaller time-steps, I’ve models with timestep: 0,03125 
(n=5), 0,015625 (n=6) and even 0.0078125 (n=7). It just takes a while 
before it’s finished calculating.
 
Kind regards,
