I am trying to run Radiance on my OpenStudio model, and have been unsuccessful in troubleshooting the severe error which is causing the simulation to fail. The simulation eplusout.err log reports:

Last severe error=ProcessScheduleInput: Schedule:Compact="TOP_NORTH T-ZONE LIGHTS SCHEDULE" has missing days in its schedule pointers

I have made a combination of changes to the Sketchup model, the Radiance measure setting, and had a look at my electric lighting schedule. None have worked so far.

Would appreciate any advice on resolving this.

That sounds like an issue with the lights schedule, whereas your attempts to fix that (changes to SU model, Radiance measure settings) won't fix that. Does the model run with EnergyPlus alone, i.e. not using the Radiance measure in the workflow at all? What does "had a look at my electric lighting schedule" mean? Could you maybe post the osm somewhere so we could take a look at it?

Hi, thanks for your response.I just tried running my model again with no changes this morning and it managed to complete the simulation. The next time I tested it, the sim failed. I have attached the link to the file below.

I made a new model and have resolved it. Turns out, I had made errors in modelling my geometry, it was hard to spot, but turns out I had repeated space types within sketch up.

Ah, I was just running it here, and I was getting EnergyPlus reporting errors about some HVAC components, probably because you didn't even realize they were in there because of the duplicated spaces. Glad you got it sorted then!
