Topology Optimization and Additive Manufacturing: FEM and Applications
Product topology optimization using Finite Element Method (FEM) optimizes material layout within a given design space, for a given set of loads, boundary conditions and manufacturing constraints with the goal of maximizing the performance of the system. This workshop aims at providing hands-on skills to product development and FEM analyse the components of product at concept stage for light weight and efficient components.
