Wufi 2D 4.6 misuses weather data by jumping to January in the middle of summer

[Joe95]

Dear Wufi-team,

I have a problem regarding 2 year simulation using one of the weather files (any of them) available inside Wufi-program. These weather files have 8760 hours of weather data as they should have. However, for some reason, Wufi uses shorter part of the weather file than one year and loops this shorter part to achieve the total length of the simulation. For example, when the simulation starts 1. January, the simulation uses the weather data until July and after July, uses weather data again starting from 1. January. How can I fix this issue?

Dear Wufi-team,

I wanted to clarify one thing. The time at which the jump to 1. January occurs varies between different weather files. The weather files seem to be ok when checked in excel. In Wufi window, the weather charts look also normal.

Hi Joe,

this could possibly be related to the indoor climate settings. What indoor climate model or conditions have you defined for the simulation?
In addition, please check under Computational Parameters → Enhanced whether the time step is set to 3600 s.

Best regards,
Christian
