Session 1: Stochastics, Robust Design and Systems Engineering to Support Simulation Driven Design

The Digital Engineering strategy of the Department of Defense, the drive to develop and use so-called digital twins, and several Certification by Analysis activities are driving the need for more simulation-driven design activities in the industrial base. This drive enables a shift of work from the physical environment into a virtual or digital environment, leading to significant decreases in the resources needed to design, produce, and keep aerospace assets operational.

To enable this strong reliance on engineering simulations, the full suite of systems engineering, robust design and stochastics methods and tools need to be employed during the simulation process. Accounting for variability and uncertainty that might occur during the manufacturing process and in the use of products is increasingly important for the assessment of component, sub-system and system performance with this simulation-driven design process.

This talk will discuss the application of automated design and simulation processes, robust design techniques, probabilistic and stochastic methods for real-world design tasks in the area of advanced gas turbines. The talk will close.

The key takeaways of this talk are that:

  • Simulation-driven design can be applied to real world challenging problems.
  • Accounting for variability and uncertainty is a key point in any simulation-driven designapproach.
  • Challenges still remain for a widespread application of simulation-driven design, especially inregulated industries.

Speaker/Presenter: Alexander Karl

Associate Fellow - Robust Design and Systems Engineering, Rolls-Royce Corporation

About Alexander

Alexander holds a PhD and MSc in Aerospace technology from the University of Stuttgart in Germany. He has 23+ years of work experience with Rolls-Royce. During this period Alexander was working in several major sites and sectors (Dahlewitz, Derby and Indianapolis). Alexander’s background is thermo-mechanical analysis but for the last 20+ years Alexander is working actively in the area of multi-disciplinary optimization, Robust Design (Design for Six Sigma) and Systems Engineering.

His main focus is the application of these tools, methods and processes to real engineering challenges. Alexander is an Associate Fellow for Robust Design and Systems Engineering within Rolls-Royce. He is also an active member of NAFEMS promoting a wider application of these methods, processes and tools.

SimScale Resources

This whitepaper highlights the benefits of cloud-native engineering simulation using SimScale and describes how fast and accurate analysis types readily available to engineering teams allow them to simulate early in the design stage, throughout the R&D cycle, and across the entire organization.

In this blog article, we discuss a centrifugal pump use case where engineers are faced with the challenge of optimizing the pump design based on seven parametric variables.

In this whitepaper, specialists from Onshape®, SimScale®, and ESTECO cover the implementation of a modern design-simulate-optimize workflow in the product development cycle.

Simulation Resources

AMD EPYC™7003 series processors with AMD 3D V-Cache™ technology boost Ansys simulation performance while cutting energy consumption in half.

In this Special Focus Issue, we take a look at new innovations in design and simulation software, as well as emerging new use cases.

In this Special Focus Issue, we take a look at new features and functions in design and simulation software, as well as the continued democratization of simulation beyond expert users, and the way that GPU acceleration has enabled real-time rendering.
