Thanks Waseem,
It is not about a specific weather file.
I'm developing my own weather model reader and processor in Simulink. I have used results from E+ to verify my model but seems to be off at some times . So, I used TRNSYS _16, TYPE 15 to determine the solar radiation on south vertical surface using Perez model and compared that to my Simulink and E+ results. I figured that TYPE 15 interpolates the weather file (even at 1 hour time step) and therefore can't use it for verification. I was expecting that TYPE15 will read the weather file without interpolation when time step is 1 hr. Is there a way with this type or others to get the values at the beginning (or end ) of each hour rather than interpolating values at the mid of the hour?
Thanks,
Saleh

Dear saleh saadi,
Salam, Please let me know the weather file name ?

But my Userdefined weather data is TRN/TRY weather data. Why does it result in
aforementioned Errors (Converging error by my past emails)?
