Multiphysics Coupling Filter
A selection filter sequence that uses Multiphysics Coupling 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 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 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.
•
