I am doing simple radiation analysis with the LB Incident Radiation component (1.1.0). The component works fine when I use BREP input geometry but shows 0 incident radiation when I use mesh input geometry.
Also tried manually offsetting the mesh, but the results for that don’t look right:
Using the same mesh input geometry works fine with the legacy version:
Looking through the code inside the LB Incident Radiation component, my hunch is that the component is not offsetting the mesh for the study_mesh and thereby using the same mesh both as the study_mesh and shade_mesh (self-shading), which is why the entire geometry is shading itself and not getting any radiation. I thought offsetting the mesh manually would fix it, but in that scenario, it seems like the offset mesh is being used both for study_mesh and for self-shading.
Please let me know what you think - if this is a bug or if I am missing something. I have attached the Rhino and Grasshopper files for reference.IncidentRadiation MeshvsBrep Input.3dm (94.6 KB) IncidentRadiation MeshvsBrep Input.gh (460.9 KB)
Also, wanted to know if the contextTransmit_ feature that allows the user to set transmittance values for context geometry is a part of LB 1.1.0 / if it would be possible to include that? I find it a very useful feature especially for modeling deciduous trees during different seasons and it would be great to have it in the new Ladybug! #wishlist
