Solar Radiation with vector direction?

Hi everyone, I have a question regarding time-dependent solar radiation.

 

I am using SolidWorks flow simulation and am going to be simulating the effects in a vacuum (pressure ~ 3e-7 Pa).  Does anyone know how I can change the solar intensity as a and direction function of time?  I am only given azimuth and elevation angles, but I'm assuming that the sun disappears once it goes over the horizon, which I do not want.  I just want a hard vector for the sun, and one that can change with time.
