I keep getting a returning error in my model that causes the simulation to fail immediately without generating any sort of useful report to explain the error. The only reports I can find indicate I have no input errors, and I can't find a reason why this failed simulation error pops up and disappears randomly. Sometimes I can run the model and it fail, then I save and run again and it works fine, then next time i try to run it it fails. It seems to indicate I'm missing a measure.rb file in the openstudio directory, but I have uninstalled and reinstalled the latest available version and keep getting the same issue. some models I have still run no problem, and often after I run one without an issue, I can go back and run a failed simulation and it will work no problem. Does anyone have any idea how to solve this so I can actually use my software and not randomly guess when the model will work or not. Any help would be greatly appreciated.
