[TRNSYS-users] negative radiation one 1 surface in type 56

[Richard Thygesen]

Hi.

I have gotten an error message in my simulation stating that one surface in Type 56 have negative radiation.
This happened when I changed the sky model for diffuse radiation from Perez to Hay and Davies.

Has anyone encountered this problem before? How can I solve this?
I am using Trnsys version 17.
Best regards
