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.

Forces:

In the name sector every force can be named individually.

...

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.

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, a local coordinate system can be chosen. More than one acceleration can be created per optimisation however only one acceleration per load case makes sense.

...

A Point Mass is considered for static load cases if an acceleration / gravity is active and for Frequency Optimisations. For Frequency Optimisations the connector can also be changed to a rigid one (RBE2) with the Advanced User Settings.
