Design and Topology Optimization using CFD and FEM
Topology optimization using Finite Element Method (FEM)/CFD 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, any modifications becomes a costly affair. This course aims at providing the much needed FEM/CFD skills to analyze the components at concept stage for light weight and efficient components.

equations, Finite element discretization techniques,
Weighted residual methods: Subdomain, Galerkin,
Petrov-Galerkin, Least square, Collocation methods; Weak
form, Rayleigh Ritz method.
    Computer Aided Designs (CAD): Drafting, learning various
methods to design components, 2D and 3D geometry generation
techniques.
    Loads and Constraints: How to apply various boundary
conditions such as pressure, forces, contacts, friction
surfaces, thermal, concentrated mass, gravity loads, etc, 
various types of supports such as fixed, pin and roller
joints, fasteners and joints, techniques for applying loads
and constraints on hole center etc.
    Connections: Techniques for modeling fasteners: nuts and
bolts, crews etc, joints, generating various types contacts
such as bonding, sliding etc

Day 2

    Static Analysis: Modeling and comparing FEM results with
theories for problems like critical stress, von Mises
stress, calculating stress concentration factor, deflection
of beams etc., designing within factor of safety, thermal
stresses, running animation etc., comparing FEM results with
theory.
    Dynamic Analysis: Design based on vibration analysis,
modeling thin-walled 3D structures with shell models, how to
extract midsurfaces from solids, surface modeling,
extracting structures natural frequencies (normal modes),
fix and free modal analysis, analysis under buckling loads,
extracting buckling modes etc,

Day 3

    Topology Optimization: theoretical background, Shape
Controls: How to apply manufacturing constraints such as
draw directions and symmetry, how to apply draw directions
(single, split and extrusion), how to apply stamping as
additional manufacturing constraints etc.
    Minimization Objective: Maximize stiffness or minimize
mass; Optimization with various constraints such as
frequency, stress, gravity, thickness and minimum factor of
safety constraint.
    Free-Form Solid Geometry: Fit new free-from solid
geometry on the optimized design, polyNURBS; exporting
geometry for further editing and analysis.
    Example from various fields such as Automotive,
Aerospace, Civil etc. will be considered for analysis.
