Reassigning the Transparent Components Region

You associate the physics continuum that you created to model volumetric radiation exchange using the VPMC model with the transparent components region. This association resets the radiative boundary conditions to defaults and clears the materials that are assigned to the transparent solid parts. Therefore, you reassign the radiative boundary conditions and reassociate these parts with their materials.

To reassign the transparent components region:
  1. Select the Regions > Transparent Components node and set Physics Continuum to Transparent Components VPMC.
  2. Reassign the boundary conditions for the transparent components:
    1. Edit the Regions > Transparent Components > Boundaries > Transparent Components/Air [0] node and set the following properties:
      Node Property Setting
      Physics Values
      Surface Material
      By Contact Subgroup
      Halogen Bulb/Air Surface Material Halogen Bulb
      Lens/Air Surface Material Lens
    2. Edit the Regions > Transparent Components > Boundaries > Walls node and set the following properties:
      Node Property Setting
      Physics Values
      External Surface Material
      By Surface Subgroup
      Halogen Bulb Surface Material Halogen Bulb
      Lens Surface Material Lens
      Surface Material
      By Surface Subgroup
      Halogen Bulb Surface Material Halogen Bulb
      Lens Surface Material Lens
  3. Reassociate the transparent parts with their materials:
    1. Expand the Transparent Components > Physics Values > Material Part Groups node.
    2. Assign the transparent components to the following material part groups:
      Material Part Group Parts
      Glass Halogen Bulb
      PMMA Lens
  4. Save the simulation.
