How are surfaces geometry checked (or not), energyplus
I have a model generated in beopt, now I'm trying to add an insulated ceiling in the garage. Beopt put an unfinished roof over the garage, so there is are 'roof' heat transfer surfaces from garage to outside. I added an insulated ceiling, but it doesn't look like it changed anything. I think I need to fix these other surfaces too, correct? Is there any checking or validation performed in energyplus for surface coherence? What would happen if there was a wall missing or something?
I don't have a windows computer (linux geek) so I borrowed one to generate the model with Beopt, now I'm attempting to make modifications without it. Am I nuts to try to do this without a frontend such as BEopt? There appears to be nothing other than windows programs.

OpenStudio works on Linux ... but sans SketchUp plug-in unfortunately.
So, without sketchup it is not much use, correct?
It would be helpful if you gave more context on why you're insulating the ceiling above the garage.
Is it because the garage will be conditioned space? If so, it might make more sense to treat the garage as living space in BEopt. Or is it because there is finished attic space above the garage? Then you should ensure there is finished attic drawn over the garage in BEopt. Both of these situations would result in the garage ceiling being insulated.
The garage and the attic are unconditioned. It was insulated mostly as a test. The garage temperatures were colder than expected or desired. The garage floor as built by BEopt was highly insulated with layers like this: Adiabatic,Soil-12in,Concrete-4in; !- Layers
Material:NoMass, Adiabatic, !- Name Rough, !- Roughness 176.1; !- Thermal Resistance {m2-K/W)
Why would they model it like this? It seems like removing that Adiabatic layer and modeling the ground temperature, or scheduling it at 10C would be a better model.
