The objective of this project is to perform external aerodynamic analysis on a detailed Boeing model. Cleaning up this model and setting up the flow analysis is not easy. Your productivity with Start CCM will increase quite a bit, after you finish this project.

Syllabus

Week 1 - Basics of CFD

This module discusses the fundamentals of CFD, its importance and applications in different fields.

  • What is CFD?
  • Uses of CFD
  • Governing equations
  • Finite Volume methods
  • Softwares

Week 2 - Basics of STAR-CCM+

In this section, we start with a brief outlook of STAR-CCM+. Then a quick introduction to the basics are provided. Finally we get to solve a basic problem right from the start till the end.

  • Brief history
  • Client – Server
  • Introduction to GUI
  • CFD workflow in STAR-CCM+

Week 3 - 3D CAD modelling

While bigger CAD systems( such as PTC Creo, SolidWorks, Siemens NX etc) allow you to create complex CAD, STAR-CCM+ has its own CAD system which can be used to design and develop models.

  • Basics of CAD modelling
  • Constraints
  • Design parameters

Week 4 - Pre-processing

Here we learn how to prepare your CAD model so that it becomes suitable for CFD simulations. We get our hands dirty trying different repair options in STAR-CCM+

  • Importing geometry
  • Splitting, combining
  • Surface repair

Week 5 - Surface wrapping

Realtime complex geometry contains millions of surface errors which cannot be fixed manually. STAR-CCM+ has the technology of Wrapping which gives a clean, water tight surface starting form a very dirty CAD.

  • Why wrapping
  • Contact prevention
  • Leak detection

Week 6 - Surface Meshing

Meshing is dividing your computational model into smaller chunks in which the equations are solved. This module exposes you about how to split your domain and getting a good surface mesh.

  • Error checking
  • Boolean operations
  • Fluid volume extraction
  • Mesh generation

Week 7 - Volume meshing

Volume meshing is the final step in the preparatory phase of your CFD simulation. We learn the different type of meshing, how to control the sizes etc.

  • Core meshers
  • Prism layer meshing
  • Mesh diagnostics

Week 8 - Boundary conditions

How do we specify the speed of the car in our CFD simulations? What is the resistance due to the presence of Radiator, Charged Air cooler in my car? These are mentioned with boundary conditions.

  • What are Boundary conditions?
  • Why BCs are needed before meshing?

Week 9 - Solver settings

This module teaches you how long to run your simulation, how to tweak the solvers if the simulation is not converging, etc. The following are discussed.

  • What are physics models?
  • How to assess convergence?

Week 10 - Turbulence modelling in STAR-CCM+

One of the biggest puzzles that scientists deal with is Turbulence. In this module, we learn which models to choose for performing external aerodynamic simulations.

  • Different models available
  • When to use what?
  • Wall functions

Week 11 - Reports, plotting

In this section, we see how to calculate the drag and lift forces, to obtain numerical values of physical quantities etc.

  • Need for reports
  • Different types of reports
  • Force, moment and frontal area reports
  • Monitors and plots

Week 12 - Post processing

A picture speaks thousand words. This module is all about getting cool images and animations. This is also about presenting and understanding the results in a better and easier way.

  • Scenes
  • Streamlines
  • Annotations
  • Volume rendering
