Hello,
I am relatively new to the world of Radiance and am currently learning and testing its commands. I have encountered an issue in the spectral matrix simulation section, and I would greatly appreciate any guidance on what I might be doing wrong.
As a first step, I followed the matrix simulation commands based on Subramanian’s tutorial. To ensure that I was proceeding correctly, I compared my results with Honeybee’s two-phase output (without DDS), and the results seemed consistent, suggesting that I had followed the process correctly.
However, when I attempted to extend this approach to the spectral mode, the results were significantly different from the non-spectral case. The results for month 6 (12:00 during the summer solstice) are somewhat acceptable, but for month 9 (equinox) and month 12 (winter solstice), the results appear to be completely incorrect.(Even 500 times larger. In the third row, I divided the results) The light distribution pattern itself seems reasonable.
