Hi all,

I'm curious to know why when i run my .idf file in the command line, I receive a Fatal Error and EnergyPlus is terminated and receive no outputs. In contrast, when i run the same .idf and .epw files in the EP Launcher, it runs perfectly (albeit 9 warnings).

Why is this? Aren't the energyplus launcher and cmd line executable the same? Shouldn't I be able to receive the same output?

Do you have multiple versions of EnergyPlus installed? This sounds like the version of EP-Launch that you are using isn't the same as the executable version you have on your PATH.

Hey Aaron,

I've just checked that both the executable and EPLaunch are both running on EnergyPlus 9.3.0

Hmm, ok. It might be related to some other issues addressed in the bug fix release of EnergyPlus v9.3. If you are using the initial release of EnergyPlus v9.3, I would recommend uninstalling that and installing the bug fix release to see if that fixes your problem.

What are the command line line arguments that you are using?

@JasonGlazer Just your classic energyplus -w weather.epw -r input.idf

@AaronBorainian I'll try that now. Will update you if anything changes. Thanks
