gencumsky strange behavior when run out of existing directory #564

Closed cdeline closed 1 month ago

cdeline commented 1 month ago

In testing the 'tracking, cumulative sky yearly' option in the GUI, I found that running the simulation out of an existing directory resulted in bogus annual results (10 Whm-2 for the full year) instead of more reasonable 223889 Whm-2. Running again in a new directory gave correct results.

I isolated the issue to a single errant file: materials\fakelights.rad. When present, it causes problems with the gencumulativesky process apparently. I'm guessing that this is not a widespread issue, so I'm closing this one as fixed (but still mysterious!)
