Hi,
My simulation is crashing quite frequently due to one Degenerate surface, that is the only severe warning I get. I checked the IDF editor, there are no surfaces with 3 or less vertices. Is there a way to locate and delete the degenerate surface?
I can attach my IDF file if needed.
If you're using OpenStudio, in SketchUp, tun the OSM Diagnostic Script: Extensions -> OpenStudio User Scripts -> Reports -> OSM Diagnostic Script
That includes the option to delete problematic surfaces, but you probably want to try finding and fixing them first as the auto-remove may mess up surface matching.
If in raw EnergyPlus, enable Output:Diagnostics,DisplayExtraWarnings for more detail on the degenerate surfaces.
I added the Output:Diagnostics,DisplayExtraWarnings, however it does not point out the degenerate surface. The error message I receive is:
* Warning * GetSurfaceData: There are 2 coincident/collinear vertices; These have been deleted unless the deletion would bring the number of surface sides < 3. * ~~~ * For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings; * Severe * GetSurfaceData: There are 1 degenerate surfaces; Degenerate surfaces are those with number of sides < 3
