An opportunity to ensure that your organisation gets
maximum benefit from using Finite Element Analysis
2-Day All-Inclusive Training Course on 3rd & 4th December: A Practical Introduction to Finite Element Analysis
FEA has become widely used and universally accepted in many industry sectors. FEA is a powerful technique, able to produce solutions to challenging structural analysis problems. The technology and computational efficiency of the method, together with the rapid increases in computer processing power means that today the scope and size of simulations far exceeds the capabilities of even a few years ago.
However, for those engineers embarking on FEA, or companies adopting the technique to improve designs or achieve certification of new products, there is a steep learning curve to overcome. Ease of use is generally assured by the software used but there are still many pitfalls and decisions that need to be made in order to obtain a good and accurate answer.
There are a bewildering array of element types, solution types, meshing methods and pre-post processing options that have to be faced. This is before engineers get down to the engineering physics behind the problem, with the 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.
NAFEMS, the only vendor neutral, not-for-profit organization with the aim of promoting the effective and reliable use of FEA, addresses this requirement by providing this two-day example-driven, practical course.
Attendees are shown the background to the FEA methodology, via simple real examples with a minimum of theory. The strength and weaknesses of various FEA techniques are shown and discussed and practical considerations of loadings, boundary conditions and structural details are shown via examples.
The assessment, validation and interpretation of FEA results are vital for delivering safe and effective products. These aspects are discussed so that attendees gain confidence in providing conservative, reliable and qualified results. Attendees build this process themselves during a final class activity and come away with an embryo Procedural Check List that should be useful in their own workplace.Another class workshop addresses report writing.
The course offers excellent guidance on how to assess and plan the task of carrying out a Finite Element Analysis. A clear understanding of the objectives of each analysis is vital and a road map for achieving this is presented. A review of the trade-off between available resource and analysis methodology is given.
This public in-person course offers important advantages:
- Concentration since attendees are not following a course while at their desk, being distracted by other requests on their time, emails, telephones, etc.
- Class interaction and discussions are positively encouraged throughout the course. Real world examples are given at every stage, drawn from the Tutor's wide practical experience and those suggested by the attendees.
- Questions and class participation are encouraged, as this is one of the key aspects of making this a unique experience for each attendee gleaming information and analysis approaches from other engineers in other sectors. Attendee project examples can often be incorporated into the class if time permits, to benefit all.
The course is completely software independent and focuses on Best Practice for carrying out analyses rather than finding the menus. Attendees are welcome to bring laptops to take notes, but they are not required.
Who Should Attend?
This course is aimed at:
- Practicing engineers who wish to learn more about how to apply finite element techniques to their particular problems in the most effective manner.
- Engineers who have started using FEA but have discovered problems and issues (cannot be used as a 'black box'.
- Managers (in many cases needing to refresh their knowledge) who review internal or external FEA reports and contract suppliers.
The material that is presented is independent of any particular software package, making it ideally suited to current and potential users of all commercial finite element software systems. This course is a must for all engineers aiming to use FEA as a reliable predictive tool for thermal, stiffness and stress analysis.
Companies moving into FEA technology to improve product designs or assess prototype failures or speed the design process will benefit from sending key engineers to this course. If you have sufficient engineers then a tailor made course maybe more suitable and NAFEMS can then work closely with you to cater for your specific industry sector or analysis type.
The course is open to both members and non-members of NAFEMS.
- 2 full day intensive course with an expert tutor
- Lunch & refreshments on both days
- Two course dinner on Tuesday evening, at the venue hotel
- Overnight accommodation on a single room, bed & breakfast basis, at the venue hotel on Tuesday evening
- A full set of printed and bound notes will be issued to every attendee.
Please note that it is intended that this concentrated course will continue through dinner in the evening, and therefore attendance is recommended.
Any alcoholic drinks purchased and extras charged to bedrooms are payable by delegates, upon departure from the hotel.
