With the Loads and Boundary Condition Tools all Boundary Conditions can be created which are required for the optimization. It can be chosen between Displacement Constraints and Structural Loads.

The force/moment can be applied on cells, surfaces, edges and points which automatically become a nondesign space. nondesign spaces. We always work with cells as load application point. The image below shows that with nondesign spaces on the left the functional areas that are important for post processes are completely available. On the right side only the surfaces were used as load/constraint application points and no post processing is possible.

To apply a constraint to a cell, the cell has to be created first. This can be done using the split tool or with a Boolean operation.What cells are and how they are created and defined is mentioned here.
