Modeling Radiative Heat Transfer in Absorbing-Scattering Media Using the RASM Interface

The Radiation in Absorbing-Scattering Media (RASM) interface, located under the Heat Transfer>Radiation branch, provides a powerful tool for modeling radiative heat transfer within participating (semitransparent) media that are assumed to be non-emitting.

This interface allows users to simulate the behavior of radiation as it interacts with a medium that absorbs and scatters energy. The RASM interface offers two different approximation methods for defining the radiative intensity equations within the participating media domains: the P1 approximation and the discrete ordinates method approximation. The choice of approximation depends on the specific needs of the simulation.
