Large Eddy Simulation Awareness Workshop Turbulence Modelling beyond RANS Large Eddy Simulation, LES, is fast becoming more readily available in the major commercial CFD codes and from the internet. Computer power is increasing rapidly too, at an affordable cost, making it potentially easier to run simulations using such methods. More CFD users are therefore becoming interested in learning about this method and its applications. While LES is very powerful it also requires some care to be used properly, as it is conceptually very different from RANS, the workhorse of industrial CFD. This seminar started by establishing and comparing the fundamental assumptions supporting RANS and LES and,...more

Abstract The laboratory of the Bay Zoltán Nonprofit Ltd. located at the ZalaZONE proving gound has the goal to test and develop Automated Driving and Advanced Driver Assistance Systems applications applying a Driver-in-the-Loop Simulator. In both topics we perform simulations and support the preparations of physical tests, further on we have our research and development topics. In our recent study we focus on to identify bottlenecks of the trending collision avoidance technology, which is one of the fastest growing ADAS feature field. Nowadays we have many different ADAS solutions which are working well on their own. Our main task now is to develop an intelligent autonomous driving algorythm...more
NRC22 Americas "Why I Attended" The following statements were made by individuals who attended NRC Americas/CAASE in recent years. The only modifications made were to remove any identifying information (e.g., company or product names). This information was captured in the conference feedback form, and was not a required field, so the response to attendee ratio is not 1:1. Why Did I Attend? Organization Type 'Presentation of our work and networking.' Academia / Research 'Networking and Making Global Presence for Company' Academia / Research 'To become more involved in the CAE community.' End-User 'The main objective was to find better ways to implement CAE.' End-User ...more
This presentation was made at the NAFEMS UK Seminar "Welding Simlation - How Much Validation is Enough?" Resource Abstract Weld modelling – the prediction of weld residual stresses using finite element techniques – has been developed and applied in the UK civil nuclear industry over the last two decades. Its development and use were driven by the extensive residual-stress-driven creep cracking problems encountered in the UK Advanced Gas Cooled reactor fleet. This effort resulted in the R6 Weld Modelling Guidelines, originally issued in 2009, which presented a state of the art, formalised approach to using finite element techniques to predict residual stresses in austenitic steel welds, with...more
Abstract Using 0-D global physics models of global temperature dependence on carbon-dioxide emissions and atmospheric lifetime we demonstrate that eliminating carbon-dioxide emissions is insufficient to prevent exceeding the global warming ?tipping point? of 2 degrees Celsius. We examine other means to limit global warming including carbon dioxide sequestration and increasing earth?s albedo. The latter is shown to be potentially much more cost-effective in managing global warming, and its positive effects can be observed immediately....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
