In the April 2019 issue of NAFEMS BENCHMARK magazine, two challenge problems are presented. The first one consists of two normal distributions, producing an analytical (theoretical) solution. The second one contains several distributions (normal, uniform and lognormal), and therefore an exact solution is not available. At the NAFEMS World Congress 2019 these problems were discussed and a few solutions were presented. In this presentation these solutions and additional ones are discussed in combination with the theoretical background and the pitfalls of these methods....more
Model Calibration and Model Validation - What's the Difference? A Discussion with the NAFEMS SGMWG 12-minute read NAFEMS SGMWG - March 22nd 2023 As part of an ongoing series, the NAFEMS Simulation Governance & Management Working Group present a discussion about the difference between model calibration and model validation. As well as reading the conversation here, you can watch the video on YouTube. The discussion was hosted by Gregory Westwater (GW, Emerson Automation Solutions) and William Oberkampf (WO, consultant), both members of the NAFEMS S imulation Governance & Management Working Group GW: Model calibration and model validation, how do you define each? And what's the distinction...more
Verification & Validation – An Introduction 7-minute read NAFEMS SGMWG - August 26th 2021 In the first of a series, the NAFEMS Simulation Governance & Management Working Group hosted a discussion introducing the concept of Verification and Validation.

NAFEMS Americas hosted its biennial regional conference, formerly known as CAASE, on June 21-23, 2022, face-to-face, at the Indiana Convention Center in Indianapolis, Indiana! The NAFEMS Americas Regional Conference 2022 (NRC22 Americas) brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, sharing experiences, discussing relevant trends, discovering common themes, and exploring future issues, including: What is the future for engineering analysis and simulation? Where will it lead us in the next decade? How can designers and engineers realize its full potential? What are the business, technological,...more
Hardware Considerations for Efficient Finite Element Analysis Overview In this webinar, we discussed what hardware configurations to pursue to get the most efficient solutions from your FEA tools. We examined various hardware components such as processors, RAM, GPUs, and hard drives and how they interact with your FEA databases and solvers. We also delved into various solution algorithms and how they are affected by your hardware setup. Finally, we explored different cluster solution options for even more capacity and speed beyond your workstation. Webinar Presentation (pdf) l Webinar Recording (WebEx) Note: The presentation and recording are only available to NAFEMS members. Back to...more

CAASE20 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, to share experiences, discuss relevant trends, discover common themes, and explore future issues, including: -What is the future for engineering analysis and simulation? -Where will it lead us in the next decade? -How can designers and engineers realize its full potential? What are the business, technological, and human enablers that will take past successful developments...more
first beta version of the VMAP Standard has now been released, and is available at vmap.eu.com . VMAP is an open and free standard for the transfer of information between simulations within a process chain, no matter what software is used to carry these out. This provides engineers with a fast solution to pass information from one calculation to another without needing to create one-off interfaces. VMAP provides a detailed and well-defined open-source standard, accompanied by a software library of input/output tools to read/write the VMAP data files and enable fast development of transfer operations between different software packages. Many software companies and suppliers have included, or are...more
