Multiphysics Coupling Selection Filter
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:
Settings
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.
