Mr. LeeTRNSYS does not output instantaneous values, so the value that you are seeing at a particular point in a printer is the average over the timestep. If you plot the temperatures at the midpoint of the timestep, as I have done in the attached spreadsheet, you will see that the profiles are identical.

Dear all. I am using the Type15-6 to read the weather data of Beijing from the data file provided by TRNSYS. However, I find that when I use different simulation time steps, the output of the weather data at particular times will be different (see attached file). I try both TRNSYS 16 and 17, and the same problem occurs in both platforms. Can anyone advise why this happens? Thank you!
