The reduced need for expert knowledge in
mathematics and computer science to use CFD, in addition to proliferation of
CFD, ensures that more organizations and newer analysts would embark on using
CFD in their design and analysis processes. It is imperative that these new
organizations and analysts know and understand the physical principles of fluid
dynamics in addition to acquiring working knowledge of CFD.
This course provides an overview of
principles, theories, and assumption in fluid dynamics, which are paramount for
the effective, proper, and optimized use of the CFD tool.

Basic FE Analysis - NAFEMS e-Learning
Training Course
Basic FE Analysis
September 11th - October
9th 2014
Four-Week Online Training Course
one 2.5 hour session per week
(including
one-week break)
Ideal for design
engineers wanting to learn more about
the basics of FEA
SPECIAL OFFER
Combine the Basic FE Analysis
e-learning Course with a place on a complementary
"live" NAFEMS training course in
E-mail e-learning@nafems.org for full details.
Course Overview
This course serves as a 'bite-size'
introduction to FEA, and is complemented by a more in-depth series of
'in-person' training courses in the
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.
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 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.
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 e-learning course to
supplement its traditional 3 day live class.
Students are shown the background
to the FEA methodology, via simple real examples with a minimum of theory. The
strength and weaknesses of the various FEA techniques are shown and discussed.
Practical considerations of loadings, boundary conditions and structural
details are shown by numerous examples.
The assessment, validation and
interpretation of FEA results are vital for delivering safe, effective
products. A process is shown which provides confidence in the results and aims
to provide conservative, reliable and qualified results.
The course offers excellent
guidance on how to assess and plan the task of carrying out a structural
analysis using FEA. A clear understanding of the objectives of each analysis is
vital and a road map for achieving this is presented. A review of the tradeoff
between available resource and analysis methodology is given.
Course Process and
Details
This course is completely code
independent. No software is required.
Each topic in the class is treated
as a building block and is presented using an overview of the physics and
theory involved. The math is kept simple and the emphasis is on practical examples
from real life to illustrate the topic. The mapping to Finite Element analysis
techniques is shown with numerous workshops. The tutor will be running analysis
interactively and involving the students in the process via Q and A periods
during each session, follow up emails and a Course Bulletin Board
Full notes are provided for the
students, together with personal passwords for e-learning backup material,
bulletin board access, etc.
Students will join the audio
portion of the meetings by utilizing the VoIP (i.e.
headset connected to the computer via headphone and microphone jacks) or by
calling into a standard toll line. If you are interested in additional pricing
to call-in using a toll-free line, please send an email to: e-learning
@ nafems.org .
Who Should Attend?
This course is aimed at engineers
who wish to learn more about how to apply finite element techniques to static
linear analysis in the most effective manner. Ideally a student should have
some experience of FEA analysis, but this is not essential. 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 structural analysis.
E-learning classes are ideal for
companies with a group of engineers requiring training. E-learning classes can
be provided to suit your needs and timescale. Contact us to discuss your
requirements.
