With the Loads & Boundary Condition Tools all Boundary Conditions can be created which are required for the optimizationoptimisation. It can be chosen between Displacement Constraints and Structural Loads (directly or remotly remotely applied).
Displacement Constraints:
...
Forces and moments can be directly or remotly remotely applied.
Direct Application
...
All forces and moments can be applied on cells, surfaces, edges and points. Please be aware, that when a boundary condtion condition is applied on a surface/edge/point only this will be automatically a Nondesign space. In most cases a bigger Nondesign space is needed, which should be created separately or the boundary conditon condition needs to be applied on a cell (volume).
...
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 optimisation however only one acceleration per load case makes sense.
...
Attention: If only an acceleration and no other load is defined in the same load case, the optimization optimisation will get rid of the whole material iterative. The acceleration force is directly dependent on the volume of the Design space. As the Design space is reduced so is the acceleration force until no material is left.
