One week unique research and industry-job-oriented workshop
Its not just a course, its a skill development program in CAE domain

Objective
The cut-throat competition for light weight product with minimum cost puts designers and engineers under huge pressure to new product design development with optimization. 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. Once the component design is freezed, it needs to manufacture as a prototype first. This course 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. Furthermore, with the advent of new technology such as 3D printing (Additive Manufacturing), wherein any complex shape can be printed easily, topology optimization becomes even more imperative. At the end of this course, participants will be able to optimize and manufacture components during the theory & practice sessions.
