Features

A feature commonly contains most of the variables and equations that a specific physics interface requires. In the Model Builder, zero or more instances of a feature can exist as a child node to a physics interface instance or another feature instance. Except for global features, they always have a selection on a specific geometry dimension (domains, boundaries, edges, or points).

Typically the governing equations of a problem are defined for a feature at the domain level and constraints and flux conditions for features are defined at the boundary level.
