Define Participating Media External Boundaries
Use the External Boundary tool to define diffusion and refractive properties of wall surfaces of participating media.
-
From the Radiation ribbon, click the
External Boundary tool.
-
Select interface surfaces between participating media model solids and external
environments.
- You can only select wall surfaces of participating media solids which are exposed to external environments (not connected to other participating or non-participating media).
- If the physics model is not set to P1 or DO, you will not be allowed to select any surfaces.
- If interface surfaces are not selected, they will be automatically assigned with the default properties set in the Thermal Radiation Physics tool.
- In the microdialog, define the diffused fraction, specular ordinate averaging method, refractive index, and external temperature.
-
From the guide bar, execute the command in the following
ways:
- Click to confirm your selection and remain
in the tool.
This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.
- Click to confirm your selection and remain
in the tool.
