Dear all

I am using the solar ray tracing to simulate the solar load on buildings.

I get very high temperatures several thousand kelvin

I have changed material properties to concrete, set my bcs according to the fluent manual example

I am running a transient simulation to simulate the sun for one day

Anyone have any idea what is wrong ?

Hello
i have not worked much on that sytem but you can
try to reduce the time step and see.
Also monitor the temp using the temp integral and see after how much time the temp is increasing.

Hope that help
