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 Digital Twins are a hot market trend right now – and for good reason. They offer companies the tantalizing promise of further-optimized product performance and extended life. This fits well with (and is enabled by) both computer-aided engineering (CAE) and the rapid emergence of data intelligence. The value of model-based engineering and virtual prototyping has evolved and improved over decades. Now, due to the availability of better information about how products are actually operating,...more
1. Determining the value of FEA Goals and Usage In this section, we will introduce you to the Getting Started with Finite Element Analysis course and outline the agenda. Next, we will discuss what to consider regarding your reasons for investing in finite element analysis software, what goals to pursue, and the importance of determining usage. ROI and Suitability In this part we will provide guidance in weighing the cost of finite element analysis software versus a trial and error approach, what the alternatives are to finite element analysis, and how to determine the suitability of FEA to your organization. We will also discuss the two main categories of finite element software users...more
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 Model-based thinking and related approaches are essential in the modern engineering environments to remain competitive. To properly implement these approaches, a fundamental understanding its definition; the composition of the related ecosystem; and the requirements to deploy is necessary. The Systems Modeling and Simulation Working Group (SMSWG) plays the pivotal role to provide that directional guidance, discuss and share ideas, help to channel the applicable standards environment, establish...more

This presentation, What are the roles of model characterizations & metadata for improved interoperability across domains, physics, platforms, and differing levels of simulation fidelity?, is from 2022. NAFEMS & ASSESS members can view / download when logged in. The ASSESS Initiative is a broad reaching multi-industry initiative with a primary goal to facilitate a revolution of enablement that will vastly increase the availability and utility of Engineering Simulation, leading to significantly increased business benefits across the full spectrum of industries, applications and users. Since June 2022, ASSESS as been part of NAFEMS....more
2. Basic Concepts and Terminology Confucius Let us be reminded of an ancient word of wisdom found in The Analects (Book XIII, Chapter 3): “If names be not correct, language is not in accordance with the truth of things.” “If language be not in accordance with the truth of things, affairs cannot be carried on to success." To get started, let's first review some key concepts. What is Physical Reality? One should never confuse an idea of physical reality with physical reality itself. “ The layman always means, when he says ‘reality’ that he is speaking of something self-evidently known; whereas to me it seems the most important and exceedingly difficult task of our time is to work on the construction...more

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 Behavioral modeling is common practice in the systems branch. It lies along the architecting-engineering continuum and is integral in gaining understanding of a system of interest (SoI), requirements derivation, technical optimization, and client satisfaction. Yet, the unprecedented systems that are to be pervasive in years to come will be so complex that systems modeling, alone, is not at all enough to answer stakeholder questions. Developers must consider the logical consequences of hypothetical...more
