Transient case in solar load model

itsme_kit · February 11, 2014, 09:40

Hi guys

I'm modelling a transient case in addition with solar load model

The time span is 7 days

In the first day, the variation of solar heat flux is reasonable, but starting from second day, the solar heat flux is always zero until finish

I attached a picture for your view

Anyone can explain this strange phenomenon?

Many thanks
