Hello everyone, I hope you are all doing well.

I'm facing the following error: * Fatal * Error occurred on EPW while searching for first day, stopped at 2019/2/16:26 IO Error=-1 I've changed the start day from use from weather file to Sunday, I've tried starting at instance 0:01 and at 0:00 and also specified the starting year of the simulation. My design days are declared typical to the .ddy file for the region I'm simulating. I also tried declaring design days from weather file but had no luck. The custom weather file runs well on energyplus but this problem occurs when simulating multiple fmus using including this file through pyfmi. Also when I run a single fmu, I'm able to output different output variables and export them to external excel files through pyfmi.

Any hints on the reason behind that would be very helpful. Thanks and Stay Safe

Update: After extended testing, the setup works only if the start time is anywhere between January and somewhere in February. Any other start day beyond that will crash be by this error. It looks like the code gives up relatively early on finding the start day. This problem does not happen when running hourly TMY file but rather with the larger minute resolution weather file.
