My openstudio app is continously crashing if I open HVAC zone tab. I am using OS app 3.3 version. My model is a 400 zones model and I am running on 16 gb ram i7 processor. Can anyone please help me to figure out root cause of crashing. https://drive.google.com/file/d/11l7Q...
I think I found a bug in our partial fix for large models by increasing stack size. Can you download, unzip, and run the installer at the URL below? Then try opening your model in this new build?

If this works for you, it will be included in the next major OpenStudio Application release.
OpenStudio Application 1.3.1 has been released and includes this fix: https://github.com/openstudiocoalitio...
There is not a hard limit to the OpenStudio SDK or the OpenStudio Application. I was able to test on a 3 year old Mac, and it just took about 5 seconds for the zone tab to render. I was even able to add heating and cooling thermostats and use select all zones to apply the thermostat to the 409 zones. Space tab also seemed fine.
I have not had a chance to try on Windows yet but I can do that later.

Just to clarify, is the OpenStudio Application crashing, or is it becoming unresponsive and freezing? Does it just happen with the linked model? Can you provide some background of the source of the model, specifically was tool was used to make or last edit it.
Thank you for the reply. First it freezes for 10 sec and shutdown abruptly. I have this issue with one more model having 600 zones and it also crashes when HVAC zone tab is clicked.
The zone model was developed using Rhino Pollination from ladybug tools with assigned properties. To edit the HVAC part I wanted to use OS app as it translates its model to OS. The simulation runs without error. Do we have zone limits in OS or is it a bug!
