This document discusses topology optimization in ANSYS. It provides an overview of IMPACT Engineering Solutions, Inc. and their analysis capabilities including ANSYS. It then describes the topology optimization process, including defining the structural problem, element types, commands used, and reviewing results. An example textbook problem and case study of optimizing a bumper design are presented. The optimized bumper design showed a 159 lb weight reduction compared to the current design. Hints are also provided such as the sensitivity of results to load configurations and mesh density.
