The Free Shape Boundary feature () can be added from the model tree under Component>Definitions using the Shape Optimization context menu. The selection of the feature has to be adjacent to a Free Shape Domain. The Free Shape Boundary feature includes the following settings:

Enter a value for the Maximum displacement dmax (default: 5 % of the geometry bounding box). A large value can give rise to error messages such as that in Figure 3-1.

Enter a filter radius Rmin for the filtering in the Filter radius field (default: 10 % of the geometry bounding box). A small value can give rise to error messages such as that in Figure 3-1.
