Greetings, Has anyone encountered this error? "GetSurfaceData: InterZone Surface Azimuths do not match as expected." The model had been running. I have no idea what would cause this. Your advise is appreciated. Thank you kindly, Matt

Matt, could you let us know which application(s) you are using? Presumably EnergyPlus, but are you using it on its own or within OpenStudio?

I am using it with Open Studio. I have a vaulted ceiling with cavities on either side.

Interzone surfaces transfer heat between zones, and they are described as two mirrored surfaces, one for each zone. So, if you have a wall, for example, in Zone 1 with azimuth 90, then the matching wall in Zone 2 should have an azimuth of 270. This error message should give you more details on the specific surfaces in question, but you may need to add Output:Diagnostics, DisplayExtraWarnings; to see that information.

Thank you to all who responded. This error has been corrected.
I was able to right click and reverse surfaces and the Azimuth problem was corrected. Also, I had surfaces that where a roof/ceiling was mating to a roof ceiling. Changing roof/ceiling to floor for these surfaces fixed the Tilt problem. Thank you, Matt

Hi @MattStewart, could you please tell me where did you right click to solve this problem?
