Introduction to Practical CFD

This course offers attendees the fundamental knowledge for using Computational Fluid Dynamics (CFD) in real-life engineering applications. Through a simple and moderately technical approach, this course describes the steps in the CFD process and provides benefits and issues for using CFD analysis in understanding of complicated flow phenomena and its use in the design process.

Best practices for reducing errors and uncertainties in CFD analysis are also presented. Many of the governing equations will be presented for illustration purposes but will not be dealt in depth in this course. Strong effort is made for the course to be CFD software neutral. However, examples from some of the more well-known and popular software will be used throughout the sessions.

Topics covered include; Definition, Role, & Basic Formulation, Governing and Model Equations, Turbulence and Heat Transfer Modelling as well as CFD Process and more.


What will you learn?

  • The basics of CFD
  • Finite Difference vs. Finite Volume vs. Finite Elements
  • Pressure vs. Density-based solvers; Implicit vs. Explicit
  • Turbulence and Heat Transfer Modelling
  • Various errors and uncertainties and how to reduce them
  • The differences between various differencing and meshing schemes
  • The errors and uncertainties in CFD and how to reduce them.

    Who should attend?

    • engineers who are new to CFD simulation
    • engineers who need a refresher on CFD

    Engineering Board PDH Credits

    *It is your individual responsibility to check whether these e-learning courses satisfy the criteria set-out by your state engineering board. NAFEMS does not guarantee that your individual board will accept these courses for PDH credit, but we believe that the courses comply with regulations in most US states (except Florida, North Carolina, Louisiana, and New York, where providors are required to be pre-approved)


    Special Note(s):

    Telephony surcharges may apply for attendees who are located outside of North America, South America and Europe. These surcharges are related to individuals who join the audio portion of the web-meeting by calling in to the provided toll/toll-free teleconferencing lines. We have made a VoIP option available so anyone attending the class can join using a headset (headphones) connected to the computer. There is no associated surcharge to utilize the VoIP option, and is actually encouraged to ensure NAFEMS is able to keep the e-Learning course fees as low as possible. Please send an email to the e-Learning coordinator (e-learning @ nafems.org ) to determine if these surcharges may apply to your specific case.

    Just as with a live face-to-face training course, each registration only covers one person. If you plan to register a large group (10+), please send an email to e-learning @ nafems.org in advance for group discounts.
