This presentation was made at the 2019 NAFEMS World Congress in Quebec Canada Resource Abstract In many industries and companies, Modeling and Simulation has been used successfully for important decisions and even some work process changes. However, in many places the use is quite “shallow” and limited to a small number of highly capable and motivated individuals. It has not become “mainstream” outside of few industries such as Automotive, Aerospace and a few others. This is classic case of an innovation being embraced by “early adopters”, but not by the so-called “early majority” and “late majority” (the vast majority of our employees). In the presentation I will show the analogy to other...more
Abstract The competition for the design and manufacturing of the best-in-class automotive products is more intense than ever due to technological advances and increased customer expectations. As a result, companies across the automotive industry are looking for innovations to improve their product design and manufacturing cycle time, cost and quality, and CAE simulation innovations and their effective implementations have long been proven to be a key competitive advantage. CAE organizations are also facing pressure to become more competitive and efficient. CAE Management and technical experts must constantly address an ever-growing demand to deliver more analytical product design and manufacturing...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 The original aircraft survivability analysis, hit calculations, has been around since the beginning of aircraft survivability. Described in the renowned Aircraft Survivability Bible, The Fundamentals of Aircraft Combat Survivability Analysis and Design by Robert E. Ball, essentially, slow, low flying, and easy to detect aircraft will have poor survivability. Also, Ball describes as hits on the aircraft increases, the aircraft survivability greatly decreases as seen in Figure 1. Two components...more

Q&A Session Questions 1. What would be the first action organisations should take when considering a strategy for Engineering Simulation? First step is identifying and gathering your Stakeholders and agreeing your Goals for Simulation. Next step is to identify your detail requirements. i.e. What is the ‘to-do’ list you need Simulation to be able to address. 2. What is the most important action organisations should take to improve their Engineering Simulation Capability? Having identified your goals and requirements the most important action is to identify your current position regarding your processes, methods, tools, models etc… Where are the gaps? 3. What are some of the common issues...more
What are the differences between various differencing and meshing schemes? What are the basics of turbulence, heat transfer, and FSI modelling? What are errors and uncertainties in CFD and how do you reduce them? Get the answers to these questions and more with this industry-leading, code-independent e-learning course. Introduction to Practical CFD New Revised Course for 2025 This course offers attendees fundamental knowledge on using CFD in real-life engineering applications. Adopting a straightforward and moderately technical approach, it outlines the CFD process and explains the advantages and challenges of employing CFD analysis in the simulation of complex flow phenomena, as well as...more
Abstract Analytical modeling and simulation of systems are traditionally done at the component or module levels and usually involve complex 3-D simulations. These types of simulations take a long time to solve but give detailed design direction. In addition, these types of simulations are typically conducted after the project gets into the development life cycle phase. Within a Systems Engineering strategy, modeling and simulation of systems are starting to be done at the product level and usually involve simplified 0-D or 1-D models. These types of simulations run very fast but only give general design direction. In addition, these types of simulations are typically needed during the planning...more
Hendrix, Van Halen, Newton and Einstein by The CAE Guy Back in the 1980s, when I was 16 or 17, I was arguing/discussing the “best” rock and roll guitarist off all time with a high school classmate of mine. While I remember it was a heated “debate” where we agreed to disagree: Long story short [1], I was advocating for Eddie Van Halen and he was advocating for Jimi Hendrix. For a little background, my classmate was a guy that seemed, at the time, to be really into rock and roll as he had the look and feel of a head banger [2,3]. I, on the other hand, was, how should I say this … a naïve computer geek and was just coming aware of the larger world around me. Sure, I had been listening to disco...more
Tutorial - Bending of a deep curved beam 3D Statement of Purpose The main purpose of this example is to demonstrate the use of 2-D plane stress elements and beam elements to model a curved uniform bar of rectangular cross section. The maximum tensile stress and the maximum compressive stress in the beam will be compared with a theoretical solution. Geometry r o = 9.1mm, r i = 7.0 mm, h = 2.0 mm Analysis Type(s) Linear material, static, small displacement. Material Steel, with Young’s Modulus = 200,000 N/mm 2 , Poisson’s Ratio = 0.3. Loading A bending moment 200Nmm applied at the top end. Boundary Conditions The bottom end is fully fixed while the top end is free. Target Solution...more
