Skylight shade generator problems

Hello, I really need an advice on this matter and ask, please, for your help.

I am running an energy simulation in order to get the indoor air temperature of my small building. Everything runs fine, except the shade brep over the skylight.

When I was running energy simulation, there was no change in the energy consumption of sun shading. So I went to hydrashare and downloaded the example of Mr. christwmakey, but it couldn’t run. The error was

  1. Solution exception:C :\Git\OS\openstudiocore\src\model\ LightsDefinition.cpp @354 : Calculation would require division by zero.
