Hello everyone. I am a Greek student working on OpenStudio.

Currently I am trying to make a "one-story" building and run the simulation for it. I've watched the OpenStudio example that there is in the library and I 've tried to fill all of the collumns needed with logical information.

Once I start the simulation there is an error shown in that i can't seem to figure out even though I've searched in the forums.

The following are what's shown in the simulation tab once I try to run the program:


Initializing workflow.
Processing OpenStudio Measures.
Translating the OpenStudio Model to EnergyPlus.

Share the OSM model and EPW please.

Alternatively, try with https://github.com/openstudiocoalitio... and check the new box "Enable Verbose Output" on the Run Tab, it should indicate what the problem is.

Hello and thanks for answering!

My osm model and epw should appear here.

Not sure about anyone else, but I'm not able to access that link. Maybe you can use Google Drive or Dropbox instead?

I uploaded everything on Google Drive.

I hope it's available now.

@Chris R. it looks like the Google Drive link works, but others need to request access to view those files. You should be able to change the sharing settings so to "anyone with the link can open" to avoid having others request access.

Looking at the workflow.osw, "seed_file" : "../000 - \u039e\u0395\u039d\u039f\u0394\u039f\u03a7\u0395\u0399\u039f.osm",, seems like your actual filename is in Greek (in the Drive link it's called 'OpenStudio.osm') . This is recipe for disaster.

Do yourself a favor and restrict naming of your simulation files to the ASCII character set. I'll even go further and say that generally speaking you should also avoid putting spaces in your folder/file names.

Hopefully your USERNAME (C:\Users\USERNAME) isn't also in greek (and doesn't contain spaces).

So in your specific case, call it 000-HOTEL.osm and not 000 - ΞΕΝΟΔΟΧΕΙΟ.osm

In fact, I can run the model named OpenStudio.osm just fine without any modifications if I just open it up in the OS App and assign the EPW. (I cannot test the issue by naming it ΞΕΝΟΔΟΧΕΙΟ as macOS does not accept these special chars)

I changed my file's name as you suggested and the problem was solved.

Thank you very much!
