TMY2 files are just text files, they can be opened with
notepad. However, it's quite difficult to read that way, but if you open it with
Excel you can separate the columns. There are a few templates that have been
made to speed this process, such as: http://sel.me.wisc.edu/trnsys/weather/tmy2data.htm
To control the time period of simulation, go to the
Assembly menu and hit Control Cards. The first two values (Start Time and Stop
Time) control the hour of the year when the simulation starts and stops,
and Trnsys uses the corresponding weather data.

data
Hi everyone,
I have a question about the weather data. The
weather data is "The TMY2s data sets of hourly values of solar radiation and
meteorological elements for a 1-year period', found in the readme file of the
weather data. I do not know how to open the weather data so I cannot see the
value of the solar radiation. Furthermore, I dont know which data has been used
in the simulation studio. For example, my simulation is only for 200hr but the
weather data should give 8760 data value base on the readme file found in
TRNSYS. How does stimulation studio know which weather data should be use. If I
want to simulate the summer's data instead of winter's data, how does TRNSYS
know? Thank you for your answer.
