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.
...
Different displacement constraint types can be chosen. The “clamped” constraint locks the translation in all three directions. With the “general” fixation the constrained degrees of freedom can be choosen chosen manually and can be named individually in the name sector for a better overview.
...
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 and , how they are created and defined is mentioned here.
...
The orientation of the force or moment can be changed directly during the creation by adding angles to the global coordinate system. Otherwise the force/moment can be referred refer to a local coordinate system.
The force/moment can be applied on cells, surfaces, edges and points which automatically become nondesign spaces. 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 processes 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.
