With the Loads & 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.
...
Constraints can be applied on cells, surfaces, edges and points which automatically become a nondesign 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.
...
The force/moment can be applied on cells, surfaces, edges and points which automatically become nondesign spacesspace. We always work with cells as load/constraint application point. The image below shows that with nondesign 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.

To apply a constraint to a cell, the cell must 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.
Pressure Load:
...
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 nondesign space.
Gravity (Acceleration):
...
An acceleration can be created by defining the value with several g’s or a magnitude. As the direction for the acceleration a direction of the global coordinate can be chosen. If the acceleration doesn’t correspond with the global coordinate system, it can be created as a vector. More than one acceleration can be created per optimization however only one acceleration per load case makes sense.
