Hi. I wonder why the Ground reflection in type 15-6 , input 4 and 5, doesn’t seem to influence the diffuse part of the radiation? I have a surface with a 70° slope and the diffuse part of the radiation doesn’t change when I change the ground reflection. I have tried one case with extremely high reflection and one with no reflection without any difference in output. Does anyone know the source of the problem? Best regards Richard Thygesen |
