Diffuse Fraction – DO model

    • Ahmed Eissa

      Hello, 

      I am simulating solar radiation incident on water passing between two layers of quartz glass. I am using DO radiation model and I want to know what is the diffuse fraction value that I should use for every surface (Upper glass surface - Glass-Water interface, etc.). Changing the value from 0 to 1 is changing the results abruptly. What is your advice on this value. 

       

      Thanks a lot.

      Given it's a fraction changing from zero to one will likely have a huge difference in the results. Click on Help in the panel to get more information.
