In this S.A.F.E.R. Simulation post, we’ll explore Five Key Quality Checks for verifying the accuracy of FEA solutions. To help us drive the conversation in a practical manner, we selected a widely available and well understood benchmark problem to model, solve and perform each Key Quality Check using ESRD’s flagship FEA software, StressCheck Professional.
ESRD Benchmarks At ESRD, we take Simulation Governance, Verification and Validation seriously. That’s why we have developed a comprehensive Handbook...
On July 17, 2019 a joint webinar on the latest developments in FEA-based 3D crack growth simulation, titled “3D Crack Growth Simulation: Advancements & Applications”, was provided by ESRD’s Brent Lancaster, LexTech’s James Harter and Hill Engineering’s Joshua Hodges. In case you missed it, the webinar recording is now available!
In the October 2018 issue of NAFEMS Benchmark magazine, ESRD Chairman Dr. Barna Szabó posed a new “FEA Puzzler”: Can you determine the progression in spring rate as a 3D coil spring is deformed? And, can you verify the accuracy of your solution? Give it your best shot!
The deadline for the NAFEMS coil spring “FEA Puzzler” submissions has been extended through June 1st! View a teaser video of ESRD’s StressCheck model and qualitative deformation results.
Strategies for mastering StressCheck Professional for a variety of Aerospace & Defense engineering applications, and a review of the available training options and online resources, will be explored.
Whereas most FEA is built on the technology of the 1950's and 1960's, StressCheck is built on active technology and proven to get the right answer faster.
WEBINAR SUMMARY
In this 2 hour webinar we will review training approaches focused on applications to make numerical simulation via finite element analysis S.A.F.E.R. - Simple, Accurate, Fast, Efficient, and Reliable.
We will have a walk through our rapidly growing and extensive Resource Library, with tips on finding the most applicable tutorial video, best practice, FAQ topic or online resource to support your simulation needs.
Case studies of the engineering applications targeted during an Introduction to StressCheck training course, such as multi-body contact, global-local analysis, and proper application of boundary conditions, will be presented.
Strategies for verifying the accuracy of engineering data will be explored, including best practices and common pitfalls engineers may encounter when assessing the quality of the results.

In this webinar we will discuss how ESRD’s S.A.F.E.R. Simulation techniques can be used to objectively verify the accuracy of engineering simulations computed by FEA.
WEBINAR HIGHLIGHTS
Why is the practice of solution verification for FEA results important? And what checks must always be performed before reporting your FEA results as “accurate”?
We will examine a variety of publicly-available and industry-applicable case studies, benchmarks and industry examples to determine the most efficient and reliable methodologies to perform solution verification.
LIVE DEMO: You will see a demonstration of ESRD’s StressCheck and its S.A.F.E.R. live dynamic results extractions for an industry example, and learn how StressCheck makes verifying the accuracy of results quick and pain-free.
In recent years, Digital Engineering contributor, NAFEMS instructor and FETraining.net developer Tony Abbey has put together a list of practical engineering simulation case studies, walk-thrus and software overviews for a variety of FEA software tools.
Watch as ESRD reproduces a selected set of his 3D detailed stress analysis case studies, and see how we compare with Digital Engineering’s published results!
ESRD is pleased to announce a new webinar, scheduled for April 22, 2021 @ 11:00 am EST.
This webinar, hosted by ESRD partner Revolution in Simulation, will present a case study in which the goal was the development of a mathematical model for supporting condition-based maintenance (CBM) decisions.
