Ironbug HVACsystem to runOSM Error GetSurfaceData

Using a different model, the errors dispplayed are:

  1. ** Severe ** GetSurfaceData: There are 12 degenerate surfaces; Degenerate surfaces are those with number of sides < 3.
  2. ** Severe ** SizeAirLoopBranches: AirLoopHVAC AIR LOOP HVAC 1 has air flow less than 1.0000E-003 m3/s.
  3. Solution exception: ** Fatal ** Previous condition causes termination.

The errors emerge only when connecting HVACsystem via SavetoFile to RunOSM. Connecting ModelToOsm to RunOSM works fine. The model for these errors is 3 HVAC Systems in Ironbug in energy simulation after corrections.
