Create/Modify Point Force Actuator

(Template Builder) Build → Actuators → Point Force → New/Modify            Shared Dialog Box
Creates or modifies a point-force actuator. Learn about point-force actuators.
 
For the option:
Do the following:
Actuator Name
If creating a point force actuator, enter a name for it.
If modifying a point force actuator, enter its database name.
Force Orientation
Select one of the following:
■Line of Sight
■Moving with Body
■Space Fixed
I Part/J Part
Enter the name of the body that the force will act upon.
Application (optional)
Enter a string for the application area.
Identifier (optional)
Enter a string for the identifier.
Function
Enter the function that defines the translational force.
Select to use the Function or Expression Builder to define a function. For information on the Function or Expression Builder, see Function Builder.
Force Limits (optional)
Enter a numerical string that defines the force limits of the actuator(s).
Displacement Limits (optional)
Enter a numerical string that defines the displacement limits of the actuator(s).
Velocity Limits (optional)
Enter a numerical string that defines the velocity limits of the actuator(s).
Acceleration Limits (optional)
Enter a numerical string that defines the acceleration limits of the actuator(s).
Units (optional)
Enter a literal string to identify the units used in the actuator definition. This string is currently not used.
Active
Select one of the following:
■on: Actuator is active.
■off: Actuator is not active.
You can also use the Actuator Set Activity dialog box to define the activity of any actuator.
If you set Force Orientation to "Line of Sight", the following options are shown:
I/J Coordinate Reference
Enter a Coordinate Reference to locate the point on the I part/J part at which the single component force will act.
If you set Force Orientation to "Moving with Body" or "Space Fixed", the following options are shown:
Location Dependency
Select one of the following:
See a Summary of Location Dependency Options.
If you set Location Dependency to "Delta location from coordinate" and one or both of the parts are flexible bodies, the following option is shown:
Selected Node, Closest Node, Closest Interface Node
Select the method to define the attachment reaction node(s).
■If you select Selected Node, you must specify the node(s) manually, and the attachment will be hardcoded to these node IDs.
■If you select Closest Node, an expression will be used to parameterize the attachment to the closest node on the flexible body.
■If you select Closest Interface Node, an expression will be used to parameterize the attachment to the closest interface node on the flexible body.
Orientation Dependency
Select one of the following:
See a Summary of Orientation Dependency Options.
Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:
■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box.
■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box.
Learn about Recording Comments.
 
Note:  
The limits are not used in the current version of your template-based product. They are optional and create string variables under the actuator user-defined element (ude) definition; the same applies to the unit, application, and identifier strings.
