To specify constraints for ALE adaptive meshing:

From the main menu bar, select OtherALE Adaptive Mesh ConstraintCreate.

ABAQUS/CAE displays the ALE adaptive mesh constraint editor.

Enter a name for the ALE adaptive mesh constraint.

Select the step in which you want to create the constraint.

Choose the type of mesh motion, Displacement/Rotation or Velocity/Angular velocity, and click Continue.

The selected motion type is not used if you constrain nodes to follow the underlying material.

Use one of the following methods to select the region that you want to constrain:

Use an existing set to define the region. On the right side of the prompt area, click Sets. Select an existing set from the Region Selection dialog box that appears, and click Continue.

Use the mouse to select a region in the viewport. (For more information, see “Selecting objects within the current viewport,” Section 6.2.) Click mouse button 2 to indicate you have finished making selections.

ABAQUS/CAE highlights the selected regions in red in the viewport.

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.

ABAQUS/CAE displays the ALE adaptive mesh constraint editor.

In the editor, select the desired mesh motion and, if necessary, the displacement or velocity components and amplitude. (For more information, see “Defining ALE adaptive mesh domains in ABAQUS/Explicit,” Section 12.2.2 of the ABAQUS Analysis User's Manual, and “Defining ALE adaptive mesh domains in ABAQUS/Standard,” Section 12.2.6 of the ABAQUS Analysis User's Manual.)

Click OK to save the named constraint and to close the editor.
