Some/most times that I open my OpenStudio models I get this warning:

weather file error

I feel like it might be more likely to happen when I am opening multiple instances of OpenStudio, though this might just be a bit of apophenia on my part. It does not really matter as it is easy enough to reselect the weather file but it is a bit annoying.

What version of OpenStudio are you using? There was an issue related to this with earlier versions. Also, nice use of 'apophenia'!

Using OS version 1.13.0, latest and greatest as far as I know.

@willyJohan, are you moving the OSM file around on your computer without also moving the directory, of the same name, that contains the epw fie? Also is this issue isolated to a specific epw file or will it happen with any file?

i definitely move/resave .osm files form time to time, i never move my weather directory. I'll see if this is the driving factor. Does the osm not reference a static epw location?

The OpenStudio model looks for the weather file in the model directory, of the same name in the same location, under the files folder. If you don't have that directory, folder, and weather file, you will get this warning. Typically, you will want to use File - Save As to move models because it will then bring the files folder (along with the other folders) and thus the weather file with it.
