Re: [EnergyPlus_Support] Crashed file for illuminance map generation
This run ultimately crashed with the same problem that your smaller file had.
The order for the ZONE objects and the DAYLIGHTING:DETAILED objects must be the
same to avoid the pointer bug in the illuminance map module. If I understand
your structure correctly, then all of the ZONE objects for the *-I and *CORE
zones must come after all of the other zones.
