Basic Finite Element Analysis (FEA)
Five-session e-learning course
Ideal for design engineers wanting to learn more about the basics of FEA
Engineering Board PDH Credits: 12.5 hours*
New to FEA and concerned about how to use it in the real world?
This course gives you practical advice with a minimum of theory.
The course offers excellent guidance on how to assess and plan the task of carrying out structural analysis using FEA.
FEAis a powerful, widely used and universally accepted technique. However, for those new to FEA there is a steep learning curve to overcome, with a bewildering array of:
- element types
- solution types
- meshing methods
- loading and constraint methods
- pre-post processing options
This is before we get down to the engineering physics behind the problem, with associated classic traps and errors. What is needed is guidance via a thorough but practical assessment of the method and how to use it in the real world.
- Background to FEA
- Defining your objectives and planning your analysis
- Making healthy models
- Real-world constraints and loading
- Engineering assessment – is your model realistic
- Integrating with CAD and geometry
- Checking the answers – guilty until proven innocent!
Why an e-learning class?
Travel and training budgets are always tight! The e-Learning course has been developed to help you meet your training needs.
If your company has a group of engineers, or specific training requirements across any subjects, please contact us to discuss options.

Feedback from former e-Learning students:
"This course did everything right. From organization to presentation to interaction, this is a good model for what online training should be."
"Tony's command over the subject and excellent teaching skills made this course worthwhile."
"Super! Doesn't get better than this. Good idea to start having e-Learning courses."
"I'm really happy not to pay a big fraction of my annual training budget to airlines and hotels. A BIG plus to e-learning."
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 w/ microphone) 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.

All sessions are recorded and made available to attendees following the end of the live class. It is perfectly acceptable to attend this class using recordings only.
The course is completely code independent, so is applicable to all FEA users
A full set of PDF notes is available for download. Each session is presented live and is available for review via a streamable recording.
Reading lists, homework submissions, supplementary data are all available for download via the special on-line forum. Interaction via the bulletin board is strongly encouraged to obtain the most from the e-learning class. Typically, the board runs for 4 weeks after the last live class sessions, giving you plenty of time to catch up with homework, review and ask questions.
Note: homework participation is purely voluntary!
