This section presents optimized topology examples generated using OptiStruct. Each example uses a problem description, execution procedures, and results to demonstrate how OptiStruct is used as a design concept tool.
The suspension bridge topology is an optimal structure generated under a distributed load. A fine mesh is generated
to simulate the design space and loads are applied. The distributed load forms a single load case.
The air conditioner bracket is an optimal topology structure generated under both linear static stiffness and modal frequency

Multi-Model Optimization can be used in applications that require optimizing parts of different sizes. This is accomplished
by using the SCALE continuation line on linked DTPL and DSIZE entries in the models on which the scaled design is to be applied.
Multi-Model Optimization is demonstrated in this Excavator example using Topology optimization design variables that are
linked between the two models.
