I have created a model (building) in openstudio and sketchup. When i try to run an energy simulation (Energyplus) I get the following message:

[11:09:26.471661 ERROR] Found error in state 'translator' with message ["E:\\Git\\OS1\\openstudiocore\\src\\utilities\\idf\\WorkspaceObject.cpp@835 : Attempt to write a disconnected WorkspaceObject out to Idf.::/ruby/2.2.0/gems/openstudio-workflow-1.3.1/lib/openstudio/workflow/util/model.rb:66:in `translateModel'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.1/lib/openstudio/workflow/util/model.rb:66:in `translate_to_energyplus'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.1/lib/openstudio/workflow/jobs/run_translation.rb:54:in `perform'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.1/lib/openstudio/workflow/run.rb:261:in `step'\n:/ruby/2.2.0/gems/openstudio-workflow-1.3.1/lib/openstudio/workflow/run.rb:210:in `run'\n:/openstudio_cli.rb:804:in `execute'\n:/openstudio_cli.rb:620:in `execute'\n:/openstudio_cli.rb:1517:in `<main>'\neval:85:in `eval'\neval:85:in `require_embedded_absolute'\neval:70:in `block in require'\neval:64:in `each'\neval:64:in `require'\neval:2:in `<main>'"]}.

Is anyone familiar with this problem?

Could you post the eplusout.err file located in the run sub folder of your model.

There won't be an eplusout.err. As the error message states (perhaps a bit cryptically), the problem happens during the forward translation (OSM -> IDF). Can you share your openstudio model?

1 Hi, I'm one of the group members. I can't attach the file, so I uploaded it in Dropbox. Best regards

Just to confirm, the model sent by Aleni15 is the one causing the trouble. THank you in advance!

I was able to run the model you sent. I do use OS 2.3.0 as opposed to you using 2.20. I also used one of my weather files (epw). If you don't use any measures I can't see why you can't run that model. Try upgrading to OS 2.3.0 or change your weather file. If you are using measures try first to run without them. Once you will be able to run the model you will find that it fails due to activity schedules which are missing from most of your zones.

What do you specific mean with "measures"?

So if I update to 2.3.0 it should do it? If so, you just saved my exams project! Thanks

There is documentation out there, perhaps you should take a look. Here's a high-level intro to what measures are: About Measures. Your error message states: Attempt to write a disconnected WorkspaceObject out to Idf. Means somewhere, it's trying to forward translate an object that was removed. This could be caused by a measure.

We haven't used any measures. So what seems to be the missing object?

Just update to 2.3.0, it works with it. You have plenty of Forward Translation warnings though.
