Setting Multiband Thermal Radiation Properties

Two spectral bands are created for this tutorial.

The first spectral band covers the range 0.1 to 3.0 μm, and the second covers the range 3.0 μm to 1.0 m.

  1. Expand the Continua > Air > Models > Multiband Thermal Radiation node.
  2. Right-click the Spectral Bands node and create a spectral band.
    A node appears within the Spectral Bands node: Thermal 1.
  3. Create a second spectral band.
  4. Edit the Continua > Air > Models > Multiband Thermal Radiation > Spectral Bands node and set the following properties:
    Node Property Setting
    Thermal 1 Upper Wavelength 3.0E-6 m
    Lower Wavelength 1.0E-7 m
    Thermal 2 Upper Wavelength 1.0 m
    Lower Wavelength 3.0E-6 m
Corresponding spectral bands must also be created for the Glass continuum. While it is possible to do this by repeating the same procedure, it can be more easily accomplished by copying and pasting.
  1. Copy from the Continua > Air > Models > Multiband Thermal Radiation > Spectral Bands node and paste onto the Continua > Glass > Models > Multiband Thermal Radiation > Spectral Bands node.
    This operation adds two nodes, Thermal 1 and Thermal 2, to the Spectral Bands node within the Glass continuum.
  2. Save the simulation.
