I have been solving a steady state internal electronics
cooling problem using 2007 floworks 64 bit windows version.
Is there supposed to be a SOLAR radiation check box under general
settings > radiation?
I ran a few analysis with radiation, environmental radiation on.
Specified solar opening radiative surfaces, but the radiation flux
is always zero. The online manual says
" Select solar radiation check box to enable directional radiation
from ambient space..." But I could not find the check box.
Also played with default wall radiative surface condition: Non
radiative and wall to ambient. Nothing moved the needle.
