With the Loads & Boundary Condition Tools all Boundary Conditions can be created which are required for the optimisation. It can be chosen between Displacement Constraints and Structural Loads (directly or remotely applied).

...

Constraints can be applied on cells, surfaces, edges and points which automatically become a Non-Design Space. To apply a constraint to a cell, the cell has to be created beforehand. This can be done using the split tool or with a Boolean operation. What cells are, how they are created and defined is mentioned here.

Force-Moment:

Forces and moments can be created by component notation or as a resulting load. In the name sector every force/moment can be named individually.

...

All forces and moments can be applied on cells, surfaces, edges and points. Please be aware, that when a boundary condition is applied on a surface/edge/point only this will be automatically a Non-Design Space. In most cases a bigger Non-Design Space is needed, which should be created separately or the boundary condition needs to be applied on a cell (volume).

The image below shows that with Non-Design Spaces on the left the functional areas that are important for the post processing are completely available. On the right side only the surfaces were used as load/constraint application points and no post processing after additive manufacturing is possible.

...

Pressure loads can be applied only on surfaces. It doesn’t matter if the surface is plane or not. The Pressure magnitude is the only value which is required. The chosen surface will automatically become a Non-Design Space. If a pressure load is applied on a surface, no other Boundary Conditions can be applied on the same or any overlapping surfaces.
