About solar intensity
 

Hello,

As you know, there is a blank for a value of solar intensity in thermal options of STAR-CD. But I'd like to input a value of solar intensity as sine wave. I can't fine any user-subroutine for it. Experts, Is it possible to do it in STAR-CD? Please let me know it.. Thank you in advance...

If you choose "User" in the solar radiation panel, it activates the usolar subroutine. You can then specify solar angle and intensity as a function of time.
