This document provides information about CAD-integrated topology optimization work being done by Prof. Krishnan Suresh and students Shaoqing Zhang and Anirudh Krishnakumar at the Engineering Research and Systems Laboratory (ERSL). Their research includes developing a new topology optimization method called PareTO that is faster than traditional methods, automatically extracting optimized topologies into CAD models in SolidWorks, and applying the process to both maximize stiffness and strength in design.
