What Bottlenecks Limit the Adoption of Simulation Governance?

October 3, 2019

While the idea of simulation governance may be easy to understand, the challenges of two potential bottlenecks must be addressed before it can adopted by engineering management. Read Dr. Barna Szabo’s latest S.A.F.E.R. simulation post to learn more.

ESRD Celebrates 30 Years in Numerical Simulation Excellence

August 1, 2019

Thirty years ago, on August 2nd, 1989, Engineering Software Research & Development, Inc. (ESRD) was founded in St. Louis, MO, USA. To commemorate this milestone, ESRD’s President & CEO Dr. Ricardo Actis would like to share a few words with you. Please take a few moments to read his commemoration.

S.A.F.E.R. Simulation Views: StressCheck Basics Q&A

April 15, 2019

In this edition of S.A.F.E.R. Simulation Views we asked Brent Lancaster, ESRD’s Principal Support Engineer, about the basics of StressCheck Professional. Learn why it was developed, what it supports, how to master it, and more!

What Are the Key Quality Checks for FEA Solution Verification?

March 5, 2019

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.

February 12, 2019

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.

ESRD Poses FEA Puzzler in NAFEMS Benchmark Magazine October 2018

October 31, 2018

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!

Watch StressCheck Demos of Digital Engineering.com FEA Case Studies

August 14, 2018

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!

Why Is a Hierarchic Modeling Framework Important?

July 19, 2018

In this S.A.F.E.R. Simulation article, we explore the concept of Hierarchic Modeling, some practical applications of Hierarchic Modeling, and the importance of implementing a Hierarchic Modeling framework in CAE software tools to support the practice of Simulation Governance.

Testimonials

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”
