[EnergyPlus_Support] Possible non-planar surface warning





Hello,

I have the following surface definition:
  BuildingSurface:Detailed,
    14UURUFLf1nxhN1M6Z5xTd,  !- Name
    Wall,                    !- Surface Type
    Masonry - Concrete Masonry Units (0.194),  !- Construction Name
    PRIVATE PARKING GARAGE,  !- Zone Name
    Surface,                 !- Outside Boundary Condition
    2Alq_duZP7$O9kLNEDNXyJ,  !- Outside Boundary Condition Object
    NoSun,                   !- Sun Exposure
    NoWind,                  !- Wind Exposure
    Autocalculate,           !- View Factor to Ground
    Autocalculate,           !- Number of Vertices
    34.862,-24.919,2.438,  !- X,Y,Z ==> Vertex 1 {m}
    35.907,-25.965,2.438,  !- X,Y,Z ==> Vertex 2 {m}
    35.907,-25.964,0,  !- X,Y,Z ==> Vertex 3 {m}
    34.862,-24.919,0;  !- X,Y,Z ==> Vertex 4 {m}

Which causes EnergyPlus to emit the following warning:
ProcessSurfaceVertices: Possible non-planar surface:"14UURUFLF1NXHN1M6Z5XTD", Max "out of line"=1.76734E-004 at Vertex # 2

I can see that the surface is (barely) non-planar. Is an error this small going to cause actual problems with EnergyPlus, or is that warning just a sanity check?

Thank you,
Cody Rose
