I just checked the file and I get the same error as you are getting. Appereantly, it is this very zone that is problematic:
In this zone there are two surfaces, which are causing errors and stop the simulation from running.
I think @chris
you have to intervene here, since something seems bugged that worked with previous versions. As I suspected, that the two odd shaped surfaces (Triangle and L-shape) are problematic, so I baked the geometry into Rhino, split the faces of the gable site of the house and the L-shaped site, joined the geometry and referenced it back into the simulation (also split a few other surfaces since they were causing errors because of being non-planar). This way the simulation runs, but it still creates the error ´1. The simulation has not run correctly because of this severe error: ** Severe ** Problem in interior solar distribution calculation (CHKBKS)`. I changed the solar distribution and now it runs without creating errors.
Here´s the fixed file: TEST2.gh
