Dear E+ Users and Support,
I add overhang and fins to a building was running fine, then a crash during the warming up period is occured. I got four sever errors, all similar to the following:
"..Max Cool Load
Comparison = 0.2492 vs Loads Convergence Tolerance=4.00E-002 - Fail Convergence"
and type of warnings first time I experience as follow:
1. "CheckConvexity: Surface="FIRSTFLOOR:F%CONC%WAITING2_ROOF_1_3_8" is non-convex.
2. "Warning ** GetHTSubSurfaceData: A Multiplier > 1.0 for window/glass door GROUNDFLOOR: G%OUTTUN1
_WALL_3_0_0_0_0_0_WIN in conjunction with SolarDistribution = FullExterior or FullInteriorExterior can
cause inaccurate shadowing on the window and/or inaccurate interior solar distribution from the window."
3. "DetermineShadowingCombinations: Surface="FIRSTFLOOR:F%CONC%WAITING2_ROOF_1_3_8" is a
receiving surface and is non-convex. Shadowing values may be inaccurate. Check .shd report file for more
surface shading details
4. " GetAirflowNetworkInput: AirflowNetwork:MultiZone:Surface= "THIRDFLOOR:VIP%VOID_ROOF
_126_0_5_0_5_4_WIN"
5. "An AirflowNetwork:Multizone:Surface object has an air-flow opening corresponding to window or door =
THIRDFLOOR:VIP%VOID_ROOF_126_0_5_0_5_4_WIN, which is within 10 deg of being horizontal. Airflows
through large horizontal openings are poorly modeled in the AirflowNetwork model resulting in only one-way
airflow.
6. "RoomAirModelUserTempPattern: Problem in non-dimensional height calculation, too low surface: EXTRA
CRACK 3 in zone: GROUNDFLOOR:G%CONC3. Average floor height of zone is: 2.006E-002
Surface minimum height is: 0.000
