[EnergyPlus_Support] WetBulb not converged - convergence error in WindowTemperatures [1 Attachment]

["Stef Cy artcygne@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hi, 

I hope somebody can help me with this issue. I created a customized weather file using 'Elements' with data extracted from a website and that corresponds only to the year 2018. In my simulation, I get the error: 

   ** Warning ** WetBulb not converged after 101 iterations(PsyTwbFnTdbWPb)

   **   ~~~   **  Routine=Unknown, Environment=RUN PERIOD 1, at Simulation time=05/28 07:10 - 07:20

   **   ~~~   **  Input Temperature = NAN

   **   ~~~   **  Input Humidity Ratio= NAN

   **   ~~~   **  Input Pressure = 96198.31

   **   ~~~   **  Resultant Temperature= NAN

Then:

   ** Severe  ** Convergence error in SolveForWindowTemperatures for window MID TVIS73-BIG

Which I guess has to do with the above Warning error, because if I use another weather file, the simulation runs without a problem.

From what I understand there might be an issue with the correspondence of the WetBulb temperature with another parameters in the weather file, but I've use a converter to verify the values of Dew Point and Dry Bulb temperature, and the values that I obtain are quite similar to those in the weather file. In brief, the data in my weather file seems to be 'reasonable', so I don't know if there is something else that influences the problem in the simulation.

The city I'm simulating is very small, so I used DDY of another city, but again, if I try with a weather file from the E+ website, I have no problem with the simulation, so I guess my problem is the customize weather file. Attached corresponding weather files.

I'd appreciate your help regarding this issue.

Steph
