Hi all,

I am having trouble trying to get my OpenStudio model to run. Normally I would start trying to run it and work through the errors with the error text file. However when I first tried to do this, everything below the ModelToIdf was "Out Of Date". Any solution to this. I think it might be that my E+ isn't the correct version or something along those lines. My OpenStudio version is 1.9.5.

Below is the image of what I am talking about. image description

This is the one error that comes up when I open errors and warnings in the ModelToIdf file. This is what is causing the simulation to not run. The others errors were simple things such as constructions.

Error with conversion: C:\Git\OpenStudio_2\openstudiocore\src\model\ModelObject.cpp@913 : Unable to deduce a value for boolean field 10 in Object of type 'OS:AirTerminal:SingleDuct:VAV:NoReheat' and named 'VAV1SE'.

Can you share your model? Drop box, gdrive or email at kyle.benne@nrel.gov would all be ok with me.

I emailed you my model. Thanks for taking a look and trying to help me out.

It looks as those it has something to do with the VAV:NoReheat model. I just cannot figure out what the problem is. I ran a previous version of the model when I was putting everything together where there was only VAVw/reheat. This worked fine but the iteration of my model after that that had VAV:NoRheat it starts failing again and not going into expand objects.

Looked at your model. Yes it does have to do with the VAV no reheat component. I recently added a new feature to vav no reheat and vav reheat so that you could control on oa requirement as opposed to just load. This introduced a new required field named "Control For Outdoor Air". The version translator that upgrades OS Models is supposed to take care of this new required field, but for some reason it did not. In the short term you can edit your osm file entering "No" for the field "Control For Outdoor Air". I rarely advocate editing osm directly, but in this case it will get you going quickly and it is a fairly isolated change.

There seems to be another report of this same thing. https://github.com/NREL/OpenStudio/is...

I will certainly have a fix in place by our 1.10 major release coming up this month.

There appear to be other errors in your model that will prevent it from simulating well or at all. Two things I noted is that there are no design days, and there are no setpoint managers on the supply outlet nodes of your AirLoopHVAC system. In any case OS should not crash. Once you work around the vav terminal issue you should be able to triage your simulation errors.

This is fixed here and will be available in 1.10.
