Use the Assign tool to apply participating media properties to selected solids. Solids which are not assigned any participating
media model are considered as non-participating.
Important: To consider the effect of media between surfaces, you can set
the radiation model to P1 Model or Discrete
Ordinate in the Thermal RadiationPhysics tool. One of these models must be
selected if you are going to define any participating media.
