Hi All

I am trying to simulate LASER CUT PANEL in Desktop Radiance using Greenup, Edmonds and Compagnon Algorithm
the simulations ran fine when I used camera option, but when I used grid option I got unrealistic readings;
in front part the readings are much more higher than the reading in a room has a  window without a shading device, while in the rear part the reading are less than the reading in a room has a window  without a shading device.
I tried to use many w/d ratio and to change the direction but I still got the same problem with different readings and numbers.
Anyone can help
best wishes
