Interfaces have to be created for every functional surface - so every surface where a boundary condition is applied to. With this Tool an offset to the inside with the input “Non-Design Space Thickness” and an offset to the outside with the input “Machining Allowance” is created. The Offset Distance is expanding the Interface to the set value to create material on front faces.
All surfaces on which a boundary condition is applied can be selected directly as an interface with the “Select Faces from Loads and Boundary Conditions” button. The Boundary Condition surfaces will be highlighted and can be selected/deselected. With “Apply” the Non-Design Space Thickness, Machining Allowance and if available Offset Distance values will be applied to the selected surfaces.
One Interfaceis created on the force application surface. Therefore, an Non-Design Space Thickness of 1 mm and a Machining Allowance of 1 mm is entered. Now select the surface and confirm the selection (MMB).
One Interfaceis created on the inner surfaces of the fixation. Therefore, an Non-Design Space Thickness of 2 mm and a Machining Allowance of 1 mm is entered. Now select the inner surfaces and confirm the selection (MMB). The outer most surface of the Fixation is not selected because is would create material outside of the Design Space.

The next steps are defined in the Studies area.
All boundary conditions must be assigned to the specific load cases, which are defined as Events. The number of Eventscan be changed by adding/deleting Eventsto the GD Scenario. The assignment of the boundary conditions to the Eventscan be made in the Loads & Constrains Window. The already created loads and constraints that concern the Design Space are listed in this window and can be activated for each Eventindividually.
