This presentation was made at the NAFEMS Americas Seminar "Model-Based Engineering: What is it & How Will It Impact Engineering Simulation" held on the 1st of October 2019 in Columbus Ohio Resource Abstract Smart Model Based Systems (SMBSE) engineering is an evolution from Model Based Systems Engineering (MBSE), by incorporating digital capabilities to expedite a quality execution and minimize unintended effects. SMBSE integrates Systems Engineering (SE) functionality with a suite of smart tools, by modelling complex systems, requirements, constraints, targets, validation and verification plans, to develop the simplest solution. The SMBSE distinctive features from the conventional MBSE include...more

Verification - How Much Should I Do? A Discussion with the NAFEMS SGMWG 4-minute read NAFEMS SGMWG - May 4th 2022 In the next part of this series, the NAFEMS Simulation Governance & Management Working Group discussed how much verification you need to do, and when to do it. As well as reading the conversation here, you can watch the video on YouTube. The discussion features William Oberkampf (WO) & Gregory Westwater (GW), members of the NAFEMS Simulation Governance & Management Working Group Is there an answer to the question “how much verification should we do”? GW: When we've had auditors or customers come in, some of them have wildly different opinions on what verification is....more
NAFEMS Americas and Digital Engineering (DE) teamed up (once again) to present CAASE, the (now Virtual) Conference on Advancing Analysis & Simulation in Engineering, on June 16-18, 2020! 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

So, what is multiphysics? Why do we need it? How do we use it, and what are the challenges? This NAFEMS Multiphysics Working Group webinar "What is Multiphysics" discusses these issues and more. An experienced panel looks at how we define the term 'multiphysics', as well as examining other aspects related to multidisciplinary and multiscale topics. This webinar is an excellent bite-size introduction to multiphysics, and a useful refresher for those with more experience in the area, or those who want to get more involved with the topic within NAFEMS and their career. The NAFEMS Multiphysics Community The Multiphysics Community allows the NAFEMS membership to engage with experts on the NAFEMS Multiphysics...more
What is Simulation Data Management? (Click on the image to download the document or click hereunder) This NAFEMS publication is available to download for free. What is simulation data management? Simulation is key to digital product development, manufacturing, and life cycle management. “Simulation” also known as “Computer Aided Engineering (CAE)” or “Analysis” is the use of computer tools, which are based on fundamental physical laws, to evaluate aspects of product performance. Companies everywhere want to take advantage of simulations in order to develop better products faster and cheaper. They want to extend simulations early, during product...more
CAE to CAD This event aimed to explore the existing, and state of the art solutions to provide feedback from CAE simulations to the CAD environment. This led to discussions which identified the limitations and barriers preventing users getting to the ultimate solution. Event Scope What feedback is required ? What data is required to support the feedback, i.e. parameters, values, precise geometry, mesh etc ? How is the feedback data managed ? How does the feedback benefit the overall design process ? Can Open Standards be part of the solution, or does it require a vendor supplied solution ? What methods are used to interpret the CAE data to provide the feedback ? How do closed loop systems...more
