Assigning the Continua to the Regions
The simulation has three pre-defined regions—Air, Opaque Components, and Transparent Components. Here, you associate each region with the correct continuum.
-
For each pre-defined region, select the region node and set
Physics Continuum as follows:
Region Physics Continuum Air Air Opaque Components Solid Components Transparent Components Solid Components
As internal radiation is not relevant in opaque solids, you
apply external radiation transfer for the Opaque Components
region:
- Select the Radiation Transfer to External. node and set
For transparent solids, you allow both internal and external
radiation:
- Select the Radiation Transfer to Internal and External. node and set
The surface radiation model relies on the spatial discretization of the
boundary surfaces into patches. By default, each boundary face has a patch. To
reduce the computational cost for this tutorial, you decrease the patch/face
proportion:
- Multi-edit the Air, the Opaque Components, and the Transparent Components regions.
- In the Multiple Objects dialog, set to 50.0.
- Click Close.
- Save the simulation .
