voxcity.simulator_gpu.solar.volumetric

Volumetric radiative flux calculation for palm-solar.

Computes 3D radiation fields at each grid cell, not just at surfaces. Based on PALM’s radiation_volumetric_flux feature.

Key outputs: - skyvf_vol: Volumetric sky view factor at each (i, j, k) - swflux_vol: Omnidirectional volumetric SW flux at each (i, j, k) - swflux_reflected_vol: Reflected radiation from surfaces at each (i, j, k) - shadow_top: Shadow height for each solar direction

Reflected radiation mode: - When include_reflections=True, the volumetric flux includes radiation

reflected from buildings, ground, and tree surfaces

  • Reflections are traced from each surface element to volumetric grid cells

  • Uses Beer-Lambert attenuation through vegetation
