[TRNSYS-users] Problem with Type 15-6 in TRNSYS 17

Title: Signature Sam
Dear TRNSYS users (and developers),

With TRNSYS 17, Type 15-6 generate the following error when trying to start a simulation between hours 1024 to 4095, with a small time step (eg 0.1 or 0.15 hour):

"Message : Unable to correctly read from the supplied data file - please check the file an re-run the simulation."

Have you ever got the same error in this configuration?


I also observed a mistake in the code of Type15 when calculating maximum and minimum of monthly avarage temperatures:

The code is as follows :

        ! Calculate the max and min monthly average
             j_min=1
             j_max=1
             Do j=2,12
                If (month_ave_T(j) > month_ave_T(j-1)) j_max=j
                If (month_ave_T(j) < month_ave_T(j-1)) j_min=j
             EndDo

With this code, in the Nothern hemisphere, January can't be the coldest month even if it is. The coldest month will generally be December that is colder that November. I think the code should be:

        ! Calculate the max and min monthly average
             j_min=1
             j_max=1
             Do j=2,12
                If (month_ave_T(j) > month_ave_T(j_max)) j_max=j
                If (month_ave_T(j) < month_ave_T(j_min)) j_min=j
             EndDo
