Unlike many other tree objects, boundary conditions are defined using both the Details and Tabular Data. This is because boundary conditions can be time, space, or frequency dependent. As such, the APIs use a type of object called Field. Fields provide access to both independent and dependent variables defined in the tabular data, as well as the function that can be defined in the Details view.
The APIs for editing boundary conditions mirror the actions that can be performed manually in the Mechanical interface. With the API, you can:
Set tabular data, which includes setting discrete input and output values
Set variable definition types (tabular, formula, or free)
This section describes APIs that enable you to manipulate boundary condition fields.
