Re: [TRNSYS-users] Values reset at end of simulation

[David BRADLEY <d.bradley@tess-inc.com>]

Michel,

  It does sound as though there is an issue with one of the printers or integrators resetting. Your Type55 parameters look okay to me. Usually Type55 feeds into a Type25 printer. Make sure that the print time (print interval) is set to 8769 as well (so long as you want only one value printed at the end of the simulation.)

  Another thought is that unless you have to run your simulation for more then a year (ie if the time has to go beyond 8769) then you could set all of the integrator reset times and print times to the variable name "STOP." STOP is a built-in variable that is the hour on which the simulation should end.

kind regards,

 David

Dear all,

I am running my simulation for one year period. Starting simulation time is 9 hr and stopping simulation time is 8769 hr. However, regardless of the step time all values are reset to 0 around timestep of 8765 hr and above. Can someone please explain to me why this is happening? Because now I am not sure if my end values used within TRNOPT are correct for the optimization. Could have something to do with using Type 24 and Type 55?

For Type 55 I am using the following parameters:

Parameter 1: Integrate or sum input-1    -1 

Parameter 2: Relative starting hour for input-1    0   

Parameter 3: Duration for input-1    8769  

Parameter 4: Cycle repeat time for input-1    8769   

Parameter 5: Reset time for input-1    8769   

Parameter 6: Absolute starting hour for input-1    0   

Parameter 7: Absolute stopping hour for input -1    8769   

Any kind of help is more than appreciated!

Thanks in advance!

Kind regards,

Michel
