Introduction to Engineering Simulation for Non-Specialists

Four-Session Live Online Training Course - 2 hours per session

 

Attend the live sessions, or view the recordings at your convenience

 

 

  • What is engineering simulation and what does it tell us?
  • What do I need to know before performing a structural simulation?
  • What is the general workflow for building and solving structural simulation models and how do we know if it’s valid?

Get the answers to these questions and more with this industry-leading, code-independent course.

 

This is the course that design, project, and test engineers, and even managers should attend as a first step toward engineering simulation democratisation. This course will empower the non-specialist to understand the value and purpose of up-front engineering simulation and optimise its implementation in analysis-driven design.

More and more, engineering simulation is being geared toward design engineers for initial sizing, configuration, and other decisions at the concept stage. The idea is to minimise the cost of design and development by avoiding costly corrections later in the development process as well as time-consuming back and forth between the design engineer and engineering analyst.

However, engineering simulation is only as good as the user’s understanding of it. In this course, the non-specialist will learn the fundamentals necessary for understanding simulation's role in the design process.

This is the intro before the intro!

Vital information includes:

  • Overview of engineering simulation, including its value, types of simulation, and its challenges
  • Qualitative overview of simulation technology and basic modelling workflow
  • Detailed breakdown of each of the steps in simulation modelling workflow along with recommendations and tips
  • Results interpretation and sources of error
  • Verification and validation

Throughout the course, the students will be engaged and challenged through a number of in-session exercises. This interaction between the students and instructor will solidify the students’ understanding of the material and accelerate their adoption of an engineering analysis mindset.

You can either attend the live sessions or take the course on-demand at your leisure.

NAFEMS e-learning gives you the best of both worlds, giving you real, practical knowledge that you can use day-to-day to improve your analyses.

What will you learn?

  • The purpose and value of engineering simulation
  • The fundamentals of structural stress analysis and simulation
  • The general simulation workflow, along with best practices and limitations
  • Results interpretation and methods for verifying and validating results


Who should attend?

The course aims to provide design engineers, project engineers, and other non-specialists with the fundamentals necessary for the optimal implementation of engineering simulation in the analysis-driven design process.

Mechanical design changes and corrections are easiest and cheapest when engineering simulation is incorporated early in the design process. Unfortunately, the lack of fundamental understanding of simulation among non-specialists presents a hurdle to the effective adoption and implementation of up-front simulation tools at the concept stage.

This course will help you and your organization clear those hurdles and help you optimize your analysis-driven design process.

 

 

The course is completely code-independent.

A full set of notes in PDF format will be available for download for each class. Each session is presented live and is available for review via a streamable recording.

Students are given access to a course discussion forum, which provides access e-learning backup material including reading lists, homework submissions, and other supplementary data. This is also where you can ask your tutor questions at any time.

Interaction via the forum is strongly encouraged to obtain the most from the e-learning class. Typically the forum stays open for 4 weeks after the last live class session, giving you plenty of time to catch up with homework, review and ask questions.

Note: homework is purely voluntary!

 

Course Process and Details

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 .

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.
