Analysis Types
Nodal Rotation is available for the following analysis types:
Dimensional Types
The supported dimensional types for the Nodal Rotation boundary condition include:
3D Simulation
2D Simulation
Geometry Types
The supported geometry types for the Nodal Rotation boundary condition include:
Surface/Shell
Wire Body/Line Body/Beam
Topology Selection Options
The Nodal Rotation boundary condition is scoped via node-based Named Selections only. For more information, see the Specifying Named Selections by Direct Node Selection Help section.
Applying a Nodal Rotation Boundary Condition
To apply a Nodal Rotation:
On the Environment Context tab, click >. Alternatively, right-click the Environment tree object or in the Geometry window and select >.
Click the Named Selection drop-down list and then select the node-based Named Section to prescribe the scope of the Nodal Rotation.
Define the X, Y, and/or Z axis as Fixed or Free. At least one Component must be defined as Fixed.
Tip: Define a Nodal Orientation for the Named Selection to control the Nodal Coordinate System.
Details Pane Properties
The Details pane selections are described below.
| Category | Property/Options/Description |
|---|---|
| Scope |
Scoping Method: Read-only field that displays scoping method - Named Selection. Named Selection: Drop-down list of available node-based Named Selections. |
| Definition |
Type: Read-only field that displays boundary condition type - . Coordinate System: Read-only field that displays the coordinate system - Nodal Coordinate System. X Component: Define the x-axis of rotation as (default) or . Y Component: Define the y-axis of rotation as (default) or . Z Component: Define the z-axis of rotation as (default) or . Suppressed: Includes or excludes the boundary condition in the analysis. |
Note: When parameterizing this boundary condition, a axis of rotation is represented by a zero (0) and with a value of one (1) inside the Parameter tab in Ansys Workbench (outside of Mechanical).
