Missing required property 'source_zone_name'

Hello together, does anybody have an idea what needs to be done here?

  1. ** Severe ** [ZoneMixing][Zone Mixing 2] - Missing required property ‘source_zone_name’.

Hi @martin6, we will need your model to be able to debug this. You can send it as a private message if you can’t share the model publicly.

It seems there is a Face in your Model that is an AirBoundary that is not adjacent to another Room/Face. You would get an explicit error message about this if you ran the model through the validation command.
