[TRNSYS-users] TRNSYS-users Digest, Vol 182, Issue 22

Thu Feb 13 19:48:21 PST 2020

Dear All

I have downloaded my location data file in .csv file but it is not
compatible with TRNSYS weather data file.
There is any other way to generate weather data file in TRNSYS or any other
software. My location data is not mention in TRNSYS weather data .

Thanks & Regards
Amit Verma
