Solar Radiation

Analysis > Radiation > Solar Radiation

Solar Radiation is a measure of the radiation emitted by the sun. This panel is used to specify the global solar radiative heat flux and parameters for the model.

Description

  • Solar heat flux
    The solar heat flux can be defined using the Create button in the panel. The values should be defined using a Time-Flux Vector table which capture the change is solar heat flux as the sun moves across the sky. The table can be either:
    1. Created Manually by entering the values
    2. Or imported (using .csv, .dat, .txt formats) using the Create button in the panel.

  • Advanced Options

    These options are set to an adequate default. Most of the time, you need not change these values.

    • Number of rays: Number of rays for the solar heat flux calculation.
    • Number of sub-rays: Number of sub-rays a ray is split into for diffuse reflections and transmissions.
    • Maximum ray reflections: Maximum number of times a single ray is allowed to reflect before it is terminated.
    • Minimum ray energy: Minimum relative energy a ray is allowed to have before it is terminated.
    • Redistribution factor: Factor for distributing the remaining energy of a terminated ray.
    • Smoothing: Flag specifying whether to spatially smooth the solar heat flux.
