Hi everyone, For windows made up of many narrow-width glass arrays, the V matrix is zero when the 3-phase method is used. The illuminance value at the specified point in the room is also zero. Is the width of the glass narrow? Is there any way to improve the accuracy so that the simulation results are not zero?

2019-07-15 21:59:49 -0500 marked best answer How to use two .xml files by 3-phase method for dynamic simulation

Hello,When using the 3-phase method for dynamic simulation, I encountered the following problems. Firstly,If a window on a wall has two different xml files on the top and bottom of the glass, like semi-transparent pv window, how to use these two xml files in the 3-phase method ? Secondly, in 3-phase method how to set the parameters of glow about glazing_glow, sky_glow and ground_glow ? What effect does the set value have? Is there a regular value? Thank you.

I want to create a model of semi-transparent pv window in radiance and use 3-phase to simulate. But the 3-phase method needs the xml format file. If the gap between the pv batteries is not uniform, how to create a window model and get the xml format file? Should i use the sketchup and how to do ?
