EnergyPlus Severe Error without Fatal Error

[DavidGoldwasser]

I know EnergyPlus having severe errors but not fatal error isn't new, but I have not run across that before with OpenStudio Server. It creates a confusing situation because the datapoint failed even though all the reporting measure rain and produced output. This is because the OSW returns "Fail" but it is hard to find out why as there are no step errors. I see two possible solutions here, other than making EnergyPlus consistent so Server Error always results in Fatal Error.

1. It would be nice if E+ and even forward translation shows up like a step, so that if it fails at either place there can be a step_error to search for.
2. If this OSW is really going to fail due to output in the EnergyPlus error file then maybe it should stop the workflow and not run reporting measures.
3. Or if we don't want to stop on Severe Errors we can change the OSW to not return "Fail"

Here is the specific Error I'm seeing, this was update to ZEDG School PAT project for OpenStudio 3.0 ** Severe ** CheckWarmupConvergence: Loads Initialization, Zone="THERMAL ZONE: CAFETERIA" did not converge after 120 warmup days.

************* EnergyPlus Warmup Error Summary. During Warmup: 0 Warning; 1 Severe Errors. ************* EnergyPlus Sizing Error Summary. During Sizing: 96 Warning; 0 Severe Errors. ************* EnergyPlus Completed Successfully-- 3041898 Warning; 3 Severe Errors; Elapsed Time=00hr 08min 32.56sec

@kbenne since you are most familiar with EnergyPlus and what level of errors mean, I thought I'd assign it to you. Not a high priority issue, but still wanted to document it.
