931. 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

932. 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

934. 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

935. Numerical Simulation in Accordance with Geotechnical Design Codes

     Advantages to verifying ultimate limit state (ULS) by numerical simulation include the checking of multiple failure forms that are not pre-determined and more accurate constitutive modelling. However, geotechnical simulation is particularly challenging due to the high non-linearity of ground constitutive behaviour and interactions with stiff structures. The next generation of the European geotechnical design standard Eurocode 7 will be the first to cover numerical simulation specifically and this webinar will provide an overview of the new rules and the reasoning behind them, together with worked examples....more

936. Incorporation of Product and System Optimization (PSO) Methods into Compact, Reliable Design Cycles

     Product and System Optimisation Incorporation of Product and System Optimization (PSO) Methods into Compact, Reliable Design Cycles Workshop Description This workshop is concerned with educational & awareness issues, including identifying barriers to successful uptake of emerging and relatively mature technologies. The workshop will be structured into two parts, a discussion session where issues are identified and technical presentations where specific methods are presented along with summaries of state of the art. The technical focus for this workshop is Design of Experiments and Response Surface Analysis. The workshop will also address the following questions: • What are the...more

937. Concluding Remarks

     7. C​oncluding Remarks Concluding Remarks Having got a valid result from the model, what should the engineer do next if the process has failed? The steps to be taken are outlined before a discussion of the role of optimisation in both parameter target setting and robustness evaluation. Quiz Previous chapter Next chapter...more

938. 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

939. 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
