Relative EPW file path may cause EnergyPlus errors

[belg4mit]

I can run sample_files/base.xml just fine (although there are quite a few of the same warnings that show up below). But once I add the messing elements to an in.xml from BEopt, the workflow fails and run.log is blank.

BEopt 3.zip Another attempt at attaching the HPXML

[shorowit]

@belg4mit Your in.xml HPXML actually ran successfully for me. Can you zip up and attach your C:\openstudio-3.5.0\ERI\workflow\ERIRatedHome directory? Maybe it will shed some light for me on why the simulations failed.

[belg4mit]

Here you go ERIRatedHome.zip

Just noticed a separate error log there. Looks like maybe the ERI invocation and XML validation tools are being run from different directories by the software, and so the relative path (the default style in the XML) to the weather data is invalid for OpenStudio-ERI. I'll try an absolute path,

[shorowit]

Great, that clearly shows the error: Could not find weather file: C:\openstudio-3.5.0\ERI\workflow\USA_GA_Atlanta-Hartsfield-Jackson.Intl.AP.722190_TMY3.epw. For some reason OpenStudio-ERI is finding the weather file but EnergyPlus is not. I'll have to look into what might cause this issue, it definitely sounds like a bug somewhere.

In the meantime, you can at least work around it by specifying an absolute path instead of relative path in the HPXML file. E.g., change <EPWFilePath>../USA_GA_Atlanta-Hartsfield-Jackson.Intl.AP.722190_TMY3.epw</EPWFilePath> to <EPWFilePath>C:/path/to/USA_GA_Atlanta-Hartsfield-Jackson.Intl.AP.722190_TMY3.epw</EPWFilePath>

The absolute path seems to have worked once I navigated out of one of the directories; it's not obvious that the system would unlink and recreate those at each invocation, and fail if it is unable to do so :-P
