Problem with the hygrothermal simulation using the self created weather file

Hello,

I am a student of sustainable building development. I just started using WUFI Plus for my Master Thesis. To get used to the software, I was doing a simple simulation of a building facade without any insulation. I created a weather file using all the mandatory data I collected for my region (for just one year - 2023) and exported it as WAC file for my Hygrothermal simulation. Everything was fine - WUFI recognized my weather file and it has the right information in the Analyze tab.

When I started my simulation (From Jan 2025 - Jan 2026), right after Jan 31, the simulation just got stuck. It is not going forward. I re checked my weather data to see if there is any anomaly in the values in the row Jan 31 and Feb 01. It was all fine. I have 8760 hours and all the required fields are as per the correct unit and within the range. I have absolutely no clue where it is going wrong. I tried with a general weather file from a database and the simulation is running smoothly. So, I assume it is something with my weather file. Please help me.

(Kindly excuse if I am not following any specific format in this forum)

Thanks,
Goutham
