I am using a link referring to the weather site …
After your reply I have tried another link for another file but unfortunately I got the same problem!
You need to add energysimPar and change the solar distribution to 0. The model you are using has nonconvex surfaces which is creating a solar distribution error.
@MohammedAlshayeb & @FabianPosadas …
I did that but unfortunately the error stills!
This is so strange Mohammed … don’t no what to do if it is Okay in your side!
Thx anyway … and I am still trying to figure out …
but by the way … how can I discover that convexity problem?
That is happening because you don’t have a value entered for max angle. Did you change it? the model you uploaded shows it at 45 degrees. But I saw that error when that input was removed.
