Creating a growth restriction

You can specify a growth restriction for a bead optimization. A growth restriction limits how much a face can grow (shell nodes at the location of the beads are moving out) relative to the initial design during the creation of the bead.

Creating a geometric restriction in a bead optimization

Context:

For a general bead optimization, you must limit the bead height by creating a growth geometric restriction that limits the displacement in the growth direction. The growth geometric restriction is required because it is the only restriction on the displacement of the nodes.

  1. From the main menu bar, select Geometric RestrictionCreate.

    The Create Geometric Restriction dialog box appears.

    Tip: You can initiate the Create procedure in two other ways:

    • Click Create in the Geometric Restriction Manager. (You can display the Geometric Restriction Manager by selecting Geometric RestrictionManager from the main menu bar.)

    • Click the tool in the Optimization module toolbox.

  2. From the Create Geometric Restriction dialog box that appears, enter the name of the geometric restriction.

  3. Select Growth (Bead) from the list of geometric restrictions, and click Continue.

  4. From the viewport, select the faces to which the growth restrictions will be applied. For more information, see Using the face curvature method to select multiple faces.

    If you would rather select from a list of existing face 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.

  5. When you have finished selecting faces, click Done in the prompt area.

    The Edit Geometric Restriction dialog box appears.

  6. Toggle on Maximum in shrink direction, and enter a positive value specifying the maximum inward displacement of a node. You can specify the maximum inward displacement of a node only for a general bead optimization.

  7. Toggle on Maximum in growth direction, and enter a positive value specifying the maximum outward displacement of a node relative to the initial location.

  8. Click OK to create the growth geometric restriction and to exit the editor.
