Optimization in ABAQUS
ABAQUS uses two major approaches in all its versions of structural optimization: topology optimization and shape optimization. Topology optimization begins with an initial model and the optimal design process continues by modifying the properties of the material in the specified elements and removing them from the design. In the second approach, ABAQUS optimizes the model by modifying the surface by moving the surface nodes to minimize the local stress concentration. Both topology and shape optimizations include constraints and objectives. This package provides a comprehensive overview of the ABAQUS optimization module with a variety of examples.
