Re: [TRNSYS-users] Meaning of simulation start time specified in the control card

Chun Kwong,
  You have to use the correct mode of Type89 (Type89d in this case). In TRNSYS 16, the start time is the hour of the year at the start of the simulation (0 to start at the very beginning of the year, 1 if you want to start on January 1 at 1AM, 744 if you want to start on February 1 at midnight). In TRNSYS 15 it was a bit different. If you are using TRNSYS 15, let me know and I will explain in more detail.
Regards,
 David

Dear Trnsys users.

I try to perform a simulation by specifying a simulation start time other than 0
or 1.  However, I find that the weather data read using Type89 seems to start
just from the beginning of the data file no matter what simulation start time I
have specified.  What is then the actual meaning of this start time?  If I want
to start a simulation not at the beginning of a year, what should I do?  Your
reply is highly appreciated.  Thank you!
