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

Hi again.

I guess it would be possible to solve this problem with an equation which never sends any negative values to type 56. What do you think about that?

Does that only cure the symptoms but not the problem?

Best regards

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
