Insertion Methods
For Current or Voltage, scope to a body, then use any of the following methods:
Select Conductor or Current on the Environment Context Tab, then select Current or Voltage.
Right-click the Magnetostatic object, or in the Geometry window then or Voltage.
For all other objects, use any of the following methods after highlighting Environment object:
Choose Inertial, or Load, or Supports, or on Environment Context Tab.
Right-click the Environment object, any load, support, or condition object, or in the Geometry window .
Right-click Options
In addition to common right-click options, relevant right-click options for this object include:
Promote to Named Selection: Available for most boundary condition objects. It enables you to create a Named Selection based on the scoping of the load. It also automatically changes the Scoping Method of the load to Named Selection and automatically specifies the newly created Named Selection in the scoping.
: Available for Bolt Pretension loads scoped to one or more Edges, Faces, or Element Faces that have the accompanying Coordinate System Behavior property set to . The option enables the application to calculate and define the internal coordinate system for this feature.
When you promote a Coordinate System, the application automatically 1) adds a new Coordinate System object the to Coordinate Systems folder, 2) sets the Coordinate System Behavior property to , and 3) specifies the newly promoted Coordinate System to the scoping.
