This past week at AA&S/PS&S 2019, ESRD’s Gordon Lehman provided a training course titled “How Do You Verify the Accuracy of Engineering Simulations?”, chatted with attendees about StressCheck^® and how it supports detailed aerostructures analyses, and exhibited at our colorful & engaging booth.

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.

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.

On Wednesday, January 16, 2019 a webinar titled “How Do You Verify the Accuracy of Engineering Simulations?” was provided by ESRD’s Gordon Lehman and Brent Lancaster.

In case you missed it, the webinar recording is now available!

January 16, 2019 @ 1:00 pm EST How Do You Verify the Accuracy of Engineering Simulations? 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 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!

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!

Converged StressCheck^® results for “The Standard NAFEMS Benchmarks: Linear Elastic Tests” are now available for download! Read more to see how ESRD’s Simulation Technology performed […]

In the coming weeks, ESRD will publish our first set of FEA-based numerical simulation results from “The Standard NAFEMS Benchmark Solutions”. Learn more […]

ESRD Benchmarks At ESRD, we take Simulation Governance, Verification and Validation seriously. That's why we have developed a comprehensive Handbook library of verified and validated models, compared our solutions to NAFEMS Benchmarks, implemented only theories that have been refereed in engineering journals and challenged our users to find a more efficient solution. Benchmarks without Simulation [...]
