A selection filter sequence that uses Multiphysics Coupling Selection Filter nodes () can only be used by a multiphysics coupling feature. Otherwise this filter works almost exactly like the Selection Component Filter but it also has a setting to specify the input selection to the filter.
To add a Multiphysics Coupling Selection Filter:
1 Under Definitions Library, right-click the Selections node () and choose Selection Filter Sequence from the context menu.
2 Right-click Selection Filter Sequence () and choose Multiphysics Coupling Selection Filter from the context menu.
The Settings window has the following section:Choose an Input selection: Intersection of coupled physics selections (the default) or Union of coupled physics selections:
• Intersection of coupled physics selections restricts the selection to the entities that are selected by all physics that are coupled to the coupling feature.
• Union of coupled physics selections restricts the selection to entities that are selected by any of the physics that are coupled to the coupling feature.
• Named Selections in the COMSOL Multiphysics Reference Manual
