Description: Determines the appropriate Topology Optimization Engine to use.
Option/Type: When set to OCM, the Optimality Criteria Method is used. When set to GOCM, the Generalized Optimality Criteria Method is used. When set to MAM, the Moving Asymptote Method is used. When set to AUTO, the solver determines the best optimization approach, based on the objective and constraint applied.
The Optimality Criteria Method can provide improved performance when the objective of the topology optimization is to minimize compliance with a fixed volume fraction. The Moving Asymptote Method is a general purpose topology optimization engine that will work with any objective or constraint. It may require more design iterations and result in an increased solution time. The Generalized Optimality Criteria Method can offer improved performance over MAM for large models.
