1074. Optimizing Organizational Models to Improve Simulation Efficiencies

      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 BACKGROUND: The benefits of Modeling and Simulation (M&S) are well known and documented both within Medtronic and in external literature. However, there is a question concerning the most efficient means to organize the inclusion of M&S into the product development cycle. We tested the hypothesis that a hybrid development process (PDP) involving both Empirical and M&S methods in Centralized or Decentralized organizational structures lead to improvements in throughput and resource utilization....more

1075. How to Perform Optimisation Under Uncertainty

      How to Perform Optimisation Under Uncertainty This NAFEMS publication, contributed by the ESTEcO engineering software company, focuses on Design Optimisation Under Uncertainty (OUU) methods. Further valuable insights on OUU are provided by the Dynardo engineering software company in a companion NAFEMS publication Irobust Design Optimization in Virtual Product Development" by Johannes Will. This publication provides: a) a description of the Smoothing Spline ANOVA (SSYANOVA) screening method, b) a comparison of Uncertainty Quantification (UQ) methods: sample based and Polynomial chaos Expansion (PcE), c) and a description of robust Design Optimisation (rDO) and reliability Based...more

1077. The Evolving World of Simulation

      Simulation is changing how we design and bring products to market, creating competitive advantages for companies that take advantage of these advances. We’ll talk about what we can expect in the evolving world of simulation— and ask essential questions to help you navigate these changes. Monica Schnitger - President and Principal Analyst, Schnitger Corporation...more

1078. How Do You Know if you are Executing the Right Simulations at the Right Time?

      Analytical modeling and simulations are a part of most companies' product development process these days. Typically, there are a group of highly specialized CAE analysts that perform various physics-based simulations that consume significant budget resources, and time. If done correctly, the simulations are typically conducted early in the development phase in order to determine if a proposed solution will work under the desired boundary conditions. However, this may not be the case if your company is resource limited or directs most of the CAE resources to use simulations to assess post-test failures. Model-based Systems Engineering (MBSE) processes have been implemented within the product...more

1079. Talking Shop with Tony Abbey - Episode 10 - What are spider elements in FEA - why rigid and flexible types?

      Talking Shop with Tony Abbey Episode 10 - What are 'spider' elements in FEA - why rigid and flexible types? NAFEMS is talking shop with Tony Abbey on a range of topics relevant to, and suggested by, the engineering analysis community. This free series is open to everyone , and we hope you can join us online. We kicked off each session with a brief presentation on the subject from Tony, and thereafter, open up the floor for written questions and thoughts from you, the audience. The sessions was moderated, allowing the host to put your questions and comments direct to Tony, and we also made each episode live on our youtube and vimeo channels, as well as sharing on social media. This week...more
