Hello, I tried to run a simple model on open studio and it failed to run. It said that a few of the surfaces had an invalid "outside boundary condition object" . I tried to use the search surfaces tool to find he surfaces and then change them manually but the problem is when I do that a chunk of the model shows up and not just the surface I want. I dont think it'll be possible for me to do that many surfaces manually like that. Can someone please help me with this ? It's driving me crazy !

Kind Regards, RMAK

The most common cause for an invalid outside boundary condition object is when there is a space in your model that has surfaces matched to another space, but the space is never put into a thermal zone. That space isn't exported to the IDF but the adjacent space still has a surface boundary conditions that refers to surfaces in the missing space. Look at the red Unassigned Thermal Zone text in the screenshot on this post.
