Hello,
I am trying to model a horizontal light pipe entering through the façade using Grasshopper–Honeybee. The internal surface of the pipe is intended to have 99% reflectance, while the exterior collector and interior diffuser will have 90% and 80% transmittance, respectively.
I converted the pipe into a mesh, triangulated it, removed degenerate and zero-area faces, removed the end caps, and oriented the normals inward. I then added it to the Honeybee Model as a ShadeMesh and ran a Point-in-Time Grid analysis. However, I cannot see any noticeable light distribution from the pipe outlets.
Is it correct to model this type of light pipe as a ShadeMesh in Honeybee? Are the Radiance material and parameters I used for the internal surface appropriate? As far as I know, Point-in-Time Grid can calculate multiple specular reflections. I have previously conducted a similar study, but I cannot identify what is wrong in this model or why there is no visible light distribution.
I have attached the Grasshopper file. @chris Thank you in advance for your help.
@Aliarch I know that you have worked on light pipe systems before. I would greatly appreciate it if you could take a look at my question and share your suggestions.
