How we can define and select specific parts of geometry in COMSOL Multiphysics

Adding selection in COMSOL Multiphysics has a very important role in simplicity of process. In this tip we will use Heating Circuit CMS to illustrate how we can use selection in the process.

Definitions

Add a selection that you can use later when applying boundary conditions and shell physics settings.

Explicit 1

  1. In the Definitions toolbar, click Explicit.
  2. In the Settings window for Explicit, type Circuit in the Label text field.
  3. Locate the Input Entities section. From the Geometric entity level list, choose Boundary.
  4. Select Boundaries 6–8 only.

Before creating the materials for use in this model, it is a good idea to specify which boundaries are to be modeled as conducting shells. Using this information, COMSOL Multiphysics can detect which material properties are needed.
