The eplusout.err file will have the specific cause of the error. Navigate to it inside the OpenStudio app (see image below) or through the OSM file directory: osm file name folder > run > 6-EnergyPlus-0 > eplusout.err

Open the ERR file and search for either "severe" or "fatal" errors, those will be the ones causing the simulation to fail.

I always use the Add Output Diagnostics measure and "DisplayAllWarnings" which provides more detailed descriptions of the errors.

I found eplusout.err but when I click on it to open it this comes out: "No operating system registered viewer for /var/folders/1t" ... ???

@ellimelimeli you'll need a text editor such as Notepad to view it and have it set as the default program for ERR files.

Thanks a lot! Will be coming back with a lot of questions, as it looks like! :)

Hello I have the same problem. Something stops the simulation. I used the Add Output Diagnostics measure but I cannot see any difference.

@obuchely the measure will not prevent errors, only help to diagnose them.
