Creating a filter restriction

You can specify a filter restriction for a bead optimization.

A filter restriction creates a more consistent workflow between bead and other optimization types. In addition, it usually leads to better optimization convergence behavior.

  1. From the main menu bar, select Geometric Restriction Create .

    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 Restriction Manager 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 Filter (Bead) from the list of geometric restrictions, and click Continue.
  4. From the viewport, select the faces to which the fixation will be applied.

    For more information, see Using the face curvature method to select multiple faces.

    To 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. Optional: By default, the region in which the Optimization module checks for the filter restriction is the same as the region in which it enforces the filter restriction. If desired, select from the top of the Edit Geometric Restriction dialog box, and select the filter region check region.
  7. Enter the filter radius in terms of value and whether absolute or relative units are used.

    If this value is omitted, double the average edge length of the model is used.

  8. Optional: Select Relative radius to input the relative radius value.

    By default, this check box is off.

  9. Click OK to create the filter geometric restriction and to exit the editor.
