You can create geometric restrictions that place boundaries on the
changes that the
Optimization module
can make to the topology of the model.
Geometrical restrictions include frozen regions from which material
cannot be removed and manufacturing constraints, such as restrictions on
undercuts that would prevent the optimized model from being removed from a
mold.
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.
From the Create Geometric Restriction dialog box
that appears, enter the name of the geometric restriction.
Select the type of geometric restriction to apply, and click
Continue.
From the viewport, select the region to which the geometric
restriction will be applied, or click Done to apply the
geometric restriction to the entire model.
By default,
Abaqus/CAE
allows you to select all of the model. To select faces or cells, use the
Selection toolbar to change the type of object that you
can select to Face or Cells. For
more information, see
Filtering your selection based on the type of object.
If you would rather select from a list of existing sets, do the
following:
Click Sets on the right side of the prompt
area.
Abaqus/CAE
displays the Region Selection dialog box containing a list
of available sets.
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.
When you have finished selecting the geometric restriction region,
click Done in the prompt area. For more information on
selecting objects, see
Selecting objects within the viewport.
The Edit Geometric Restriction dialog box
appears. The content of the dialog box depends on the type of geometric
restriction you are creating.
Click OK to save your data and to exit the
editor.
