The Free Shape Shell feature () can be added from the model tree under Component>Definitions using the Shape Optimization context menu. The selection of the feature cannot be adjacent to a Free Shape Domain. It is recommended not to use this feature on boundaries adjacent to meshed domains. The Free Shape Shell feature includes the following settings:

Enter a value in the Maximum displacement field (default: 5 % of the geometry bounding box).

Enter a radius Rmin for the filtering in the Filter radius field (default: 10 % of the geometry bounding box).
