Defining a secondary base motion boundary condition

To create a new secondary base boundary condition, follow the procedure outlined in Creating boundary conditions (Category: Mechanical; Types for Selected Step: Secondary base).

To edit an existing boundary condition using menus or managers, see Editing step-dependent objects.

Select a region in the viewport. You can use the angle method to select a group of faces or edges from geometry or a group of element faces from a mesh. For more information, see Using the angle and feature edge method to select multiple objects. When you have finished selecting, click mouse button 2.

If the model contains a combination of mesh and geometry, you must choose the type of region to which you want to apply the boundary condition. From the prompt area, select one of the following:

• Click Geometry to apply the boundary condition to geometry or to a reference point.

• Click Mesh to apply the boundary condition to a native or orphan mesh selection.

To select from a list of existing sets, do the following:

1. Click Sets on the right side of the prompt area.

   Abaqus/CAE displays the Region Selection dialog box containing a list of available sets.

2. Select the set of interest, and click Continue.

   Note:

   The default selection method is based on the selection method you most recently employed. To revert to the other method, click Select in Viewport or Sets on the right side of the prompt area.
