Dear all,

I am running a simulation for a 5 day solar radiation on a group of buildings. I am using the DO radiation model and using solar ray tracing for the solar load. I would like to ask

1. What is the appropriate input for the update parameter for the TIME STEPS PER SOLAR LOAD UPDATE ?

2. As I was simulating the 24 hours for 5 days with each time step as one hour, I assume this would be 1. However when I do this the temperatures become very high at the end of the day reaching 100 degrees C.

3. Would it be better to use the DO irradiation model ?


Thanks in advance

Please how can i make the solar radiation as a heat flux boundary condition by FLUENT?
