Set angular global load in the Simulation workspace

Global loads are applied to all parts or bodies in the study. Only one global load can be applied per study.

These instructions assume you are setting up one of the following studies:

Structural buckling

Static stress

Nonlinear static stress

Modal frequencies

Shape optimization

1. In the Simulation workspace, Setup tab, select Loads > Angular Global Load .
2. In the Angular Global Load dialog, choose one of the following three Direction Type options:
   • Normal: For this direction type, you must select two entities to orient the rotation axis of the angular load:

     • Location Reference: Pick a flat face, an edge, or a vertex to define the location of a point along the axis of rotation. Three manipulator arrows appear around the axis location.You can drag these arrows of specify an offset in the Axis Location section (X Distance, Y Distance, and Z Distance).

       Note: The X, Y, and Z distances do NOT correspond to the global coordinate system. They are based on the local coordinate system of the selected location reference entity.

     • Direction Reference: Use this reference to define the plane of rotation (perpendicular to the axis of rotation). Click Direction Reference to change from the Location Reference selection mode to the Direction Reference selection mode. Then, pick a flat face to define the plane of rotation, which is parallel to the selected flat face. You cannot choose the same face that you picked for the Location Reference. If the plane of rotation is parallel to the Location Reference face, choose another parallel face instead for the Direction Reference.

   • Axis: Select one of the following types of entities to define the axis of rotation:
     • Straight Edge: The axis of rotation is located collinear with the selected edge.
     • Cylindrical Face: The axis of rotation is located collinear with the centerline of the selected cylindrical face. The face can be a full cylinder (360°) or a partial cylinder (< 360°).
   • Vectors (x, y, z): Specify the X, Y, and Z components of acceleration based on the global axes.
3. If needed, click Velocity to show or hide the Velocity Components settings.
4. Optionally, in the Velocity Components section, click Override Units to choose alternative units for defining the angular global velocity. Then, choose the desired units from the drop-down list.
5. In the Velocity Components section, specify either of the following parameters, depending on your selection in step 2:
   • The Magnitude of the angular velocity, or
   • The components of angular velocity about the X, Y, and Z global axes.
6. If needed, click Acceleration to show or hide the Acceleration Components settings.
7. Optionally, in the Acceleration Components section, click Override Units to choose alternative units for defining the angular global acceleration. Then, choose the desired units from the drop-down list.
8. In the Acceleration Components section, specify either of the following parameters, depending on your selection in step 2:
   • The Magnitude of the angular acceleration, or
   • The components of angular acceleration about the X, Y, and Z global axes.
9. Click OK to apply the load and close the dialog.
