Your code looks good. Not sure why it is failing let me take a look.

[santoshphilip]

closed by mistake. reopened now.

[santoshphilip]

I tested it with the file HVACTemplate-5ZonePTAC-DOAS.idf from the example folder I tested it with different version of Energyplus

Results are::

fname = "./ver9_2/HVACTemplate-5ZonePTAC-DOAS.idf" - runs fine
fname = "./ver9_6/HVACTemplate-5ZonePTAC-DOAS.idf" - runs fine
fname = "./ver22_1/HVACTemplate-5ZonePTAC-DOAS.idf" - does NOT run

This may be a problem with version 22.1 If that is so, an issue will have to be opened at the Energyplus issue tracker. I would like to have it tested on a windows machine with EP Launch before opening an issue.

@bbrangeo , If you can get access to a windows machine, can you test it with the EPLaunch (run it without eppy) ?

[santoshphilip]

OK I tested it on a windows machine using EPLaunch. It works fine

hmmm ... now what ?

[santoshphilip]

works fine using EP-Launch-Lite on the Mac. Have the command line arguments or options changed ??

[santoshphilip]

On a Windows machine the following works

C:\EnergyPlusV22-1-0\energyplus.exe -w ..\weather\USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw -x HVACTemplate-5ZonePTAC-DOAS.idf

[santoshphilip]

On a Windows machine the following works

C:\EnergyPlusV22-1-0\energyplus.exe -w ..\weather\USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw -x HVACTemplate-5ZonePTAC-DOAS.idf

on a Mac the following does NOT work

/Applications/EnergyPlus-22-1-0/energyplus-22.1.0 -w ../weather/USA_CO_Denver-Stapleton/USA_CO_Denver-Stapleton.724690_TMY.epw -x HVACTemplate-5ZonePTAC-DOAS.idf

EP-Launch-Lite on the Mac works fine with ExpandObjects

Some questions arising from these experiments:

• Why does the command line with ExpandObjects work on a Windows machine
• Why does the command line with ExpandObjects NOT work on a Mac
• How does EP-Launch-Lite work on a mac with ExpandObjects
  • Maybe ExpandObjects does not use command line OR it uses it differently

Next step may be to open an issue on the Energyplus issue tracker

[bbrangeo]

Hi, I switched to windows. On a Windows machine, the command line works

[santoshphilip]

I tested with Energyplus 22.2

The command line works on it.

/Applications/EnergyPlus-22-2-0/energyplus-22.2.0 -w ../weather/USA_CO_Denver-Stapleton/USA_CO_Denver-Stapleton.724690_TMY.epw -x HVACTemplate-5ZonePTAC-DOAS.idf

@bbrangeo , can you test your code with E+ 22.2 on you non-windows machine. I think it should work

[santoshphilip]

I am assuming that this issue is resolved. Energyplus version 22.1 has a problem. Version 22.2 works fine
