Short term course on Applied CFD and FEM, Dec 2016, India

Posted By: Om Prakash Singh
Date:Sat, 7 May 2016, 8:41 a.m.

India, December 24, 2016

This is one-of-its-kind industry oriented 7-day short term course
that offers unique experience of both the field of FEM and
CFD that covers broad range of topics on FEM and CFD.
At the end of the course, the
participants are expected learn the theory as well as
quality meshing and analysis techniques of various types
(1D, 2D, 3D in FEM, CFD problems).



The main topics of the course would be:

Introduction and application: Use of CAE (CFD and FEM)
in various engineering fields, design and failure analysis
using CAE etc.

Basic theory of CFD and FEM: Governing differential
equations, discretisation techniques- Finite volume method,
Finite difference methods, Explicit, Implicit and
Crank-Nicolson’s algorithm; stability of solutions, Finite
element discretization techniques, Meshing techniques, weak
form, Rayleigh Ritz method, modelling of convection-
diffusion problems, Introduction to turbulence, concept of
boundary layer.

Complex geometry handling: feature curves, surface
organization, free edges, boundary surfaces, other
pre-processing techniques.

1-D Meshing: Introduction to meshing, when to use 1-D
meshing, meshing in critical areas, element section, beam
element, rigid elements, fasteners, problems based on 1-D
FEM and comparison with exact theory.

2-D Meshing: When to use 2D simulations, techniques for
2D FEM, CFD simulation, mid-surface, different types of
element and their displacement function, Family of 2-D
elements: plane stress, plan strain, plate, membrane, thin
shell etc., effect of mesh density, effect of biasing in
critical region, boundary conditions, how not to mesh,
shrink wrap meshing, effect of mesh size on results (in FEM
and CFD), problems based on 2D FEM and CFD and comparison
with exact theory.

3-D Meshing: When to use 3D FEM and CFD simulations,
boundary layer mesh generation, elements types, DoF for
solid elements, brick meshing, prism layer, how not to mesh,
effect of mesh size on results (in FEM and CFD)

Mesh Quality and Checks: Compatibility and mechanisms,
shells to solids, beam to solids etc, General element
quality checks: skewness, aspect ratio, warpage, jacobian;
2-D quality checks, quality checks for tetra meshing, brick
mesh quality checks, quality checks for CFD mesh, grid
independence study

Linear Static and Dynamic Analysis: Stiffness matrix,
stress and strain calculations, FEM model for linear
analysis, error analysis, design problems based on linear
analysis, Theory of dynamic analysis: forced and free
vibration, mode shapes, harmonic analysis, design techniques
for avoiding resonance.

Thermal Analysis: Conduction, convection and radiation
heat transfer, structured and unstructured meshing, thermal
analysis using FEM/CFD.

Real to Virtual: Reverse engineering techniques,
creating 3D CAD designs from real objects, use of camera in
converting still images into 3D models, post-processing
techniques for quality remeshing etc.

FVM vs. FEM: Which gives better result: Finite volume
method or Finite element method? Solving standard problems
with both FVM and FEM based codes, linear static and fluid
flow problems etc.

Applied FEM and CFD: CFD, NVH analysis., application
CFD and FEM in biomedical, implant designs such as
Orthopaedic implants, automotive (engine modeling),
aerospace (aerodynamic), civil (building modeling: static
and dynamic analysis), modeling stress concentration, lift
and drag prediction etc.
