[TRNSYS-users] Internal error in solar radiation distribution

[miriam di matteo <dimatteo.1585179@studenti.uniroma1.it>]

Dear TRNSYS Users,

I'm simulating a building (Type 56) heating system with Heat Pump (Type 941) and Fan Coil (Type 996). To resolved a convergence error I set the time steps to 1 minute.

But now, I have this new error:

Message: Internal error in solar radiation distribution (sumsitot) of 55.514 % at time 184.83 wave length band no.3

1:total solar,

2:visual solar,

3:non visual solar  

I try to find a solution and advice in TRNSYS-users Archives, but I was unable to resolve the error.

How do I solve it? Where is the error generated?

Would anyone know how to help me? 

Thank you in advance,

regards

Miriam
