Changing the input irradiance #22

Hi,

I hope all is well. I wanted to change the radiation input by using vmcboundary.lightsource_irradiance (), but it does not change fluence output when I change the irradiance from 1 to even a large number. How can I change the boundary condition by changing the input light that radiates to the surface?

Best, Sajjad

Hi Sajjad, sorry for the late and brief response but I think the irradiance is normalised to "1" (as if the power of the light source is 1 W) so that only differences between elements matter. So for example if you have two light sources in the system with irradiance 1 and 2, it is the same as 1000 and 2000. Only relative differences matter. More details are in the Continuum paper. Best, Aleksi
