Re: [EnergyPlus_Support]

Excuse me for second email.
I check your file again in Autocad also Sketchup.
You Zone definition is completely false:
1- E+ only can recognize Four corners for each surface but you modeled many surfaces (ceiling, Roof) that they have more that 4 surfaces
2- you didn't define different surfaces for outside and inside areas.
3-your model was broken at sorth- west . you can check you model by click on Drawing file or import it by open studio into Sketchup 
I suggest you to watch this Clips

Dear All,

I constructed a six floored building with 2 zones. One zone for basement as it is underground and the other zone for all above floors. I am getting fatal error as below,  I have an important paper due soon, I have been trying to create this building model since 2 months now. I have attached my idf file if you could please go through it. I did enter appropriate boundary condition as ground for basement still I am getting the error. So if you could please help me solve this error. thank You.
