Base surface does not surround subsurface
I'm working on an OS/E+ model that has some tricky geometry with many non-rectangular and non-vertical walls. I have punched windows located on these surfaces and I'm receiving the following warning(s) on many of the subsurface windows...
** Warning ** Base surface does not surround subsurface (CHKSBS),
The warning is then followed by either Overlap Status=Partial-Overlap or Overlap Status=No-Overlap
I am still able to run a successful simulation and the results do not appear to be way out of line. Everything appears correctly in the SketchUp rendering as well.
Does the warning above impact the simulation in any significant way?
I expect this is just a rounding error creating an inadvertent warning. To confirm the surfaces are where they are expected you could use the view model or view data measures in the OpenStudio applciation, or export a DXF from EnergyPlus.
The SketchUp plugin shows the surfaces correctly and there are no input file errors and warnings when opening the model in SketchUp. I also ran the 'view model' measure as suggested and the surfaces show up in the web browser view of the HTML.
I do have windows (subsurfaces) that touch 1 edge of a surface in some situations.
I imported 3D DWGs in SketchUp and traced the necessary elements in SketchUp.
