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

Dear Samuel Hennaut,

We are currently looking into an issue that has to do with that error. In the mean time, if you could change your timestep to any 1/(2^n) hr, such as 0.125 hr, I think it should work fine.

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

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
      &n! bsp;         If (month_ave_T(j) < mon th_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
           &n! bsp; EndDo
