Keynote Presentations

Multiphysics CAE: A Necessity for Durable and Reliable Vehicle Design
Prashant Khapane, JLR

The driving factors for durable and reliable vehicles are capacity(Inner noise) and demand (outer noise). One can further break it down into five noise factors, namely piece to piece, change over time, customer usage,external environment, and system interaction. Many of the tests used to design vehicles are single noise factor tests in order to either come up with the demand (fatigue/loads to design) or check the capacity. However from theattribute perspective at vehicle level it is important to consider multi-noisefactors while designing. It is no wonder that the system interaction plays themost important role and demands for a multi-physics CAE approach to solve theproblems. The presentation is about such scenarios and usage of CAE to solvethose.

Smart Manufacturing: CAE as a Service, On Demand, in the Cloud
Wolfgang Gentzsch, Uber Cloud

The benefits for small and medium size businesses (SMBs) of using High Performance Technical Computing (HPTC) within their design and development processes can be huge. However, the vast majority of SMBs perform virtual prototyping or large-scale data modeling still on their desktop computers. But because of the well-known limitations of these systems, many companies can't solve more sophisticated application problem, in shorter time. Therefore, most of these companies have a real need for additional HPTC.

In this presentation we will discuss two options for SMEs for acquiring additional HPTC power: buying an HPTC server or using cloud computing. Both options come with great benefits, but also with some challenges. We will present an overview of the status and trend of HPTC in the Cloud for digital manufacturing SMBs. And we will look at the reasons why we believe the acceptance of HPTC in the Cloud will strongly increase in the near future, especially for digital manufacturing. Finally, we will provide an outlook on how the UberCloud Experiments can accelerate the process of go-to-market and user acceptance of this new computing paradigm, and close with a few real-life hands-on case studies of CAE in the Cloud.

Low-Voltage Circuit Breaker Arc  Interruption – A Multiphysics Modeling Challenge
Christian Rümpler, Eaton

Despite the increasing importance of power electronics in the area of high current switching, electro-mechanical switching devices like low-voltage circuit breakers are still the workhorses in industrial and residential power distribution systems. They provide excellent protect on towards overload and short circuit failure conditions, while power losses are small compared to semiconductor devices. Circuit breakers provide safe galvanic insulation - a must have in a majority of applications.

With increasing need for space savings and therefore increasing power density, the development of these devices needs to be supported by the best tools available to limit development risks. A major risk is associated with the interruption of high short circuit currents, causing large thermal and mechanical stresses.

Therefore a modeling approach was developed that covers the main physical processes during high current arc interruption in low-voltage circuit breakers. Multidisciplinary code-coupling is performed, combining the solution of fluid, electromagnetic and radiation equations. More complexityis added by considering the travel of the movable contact arm of the breaker inthis coupled approach.

Fluid, Solid and Radiation Modelling in Multiphysics Systems
Christopher Pain, Imperial College London

Here we present an outline of the work by Applied Modelling & Computation Group on development of radiation transport/neutronics, thermal hydraulics/multi-phase flows, and solids mechanics modelling. We present the coupling of these models together with their applications which now cover a range of industrially important, multi-physics phenomena. Current applications include: criticality in fissile solutions, nuclear reactor analysis and accident scenarios, ocean and atmospheric prediction, pollution dispersion through urban environments, single and multi-phase flows and coastal defense structures. To maximise computational efficiency and accuracy, we employ adaptive mesh resolution to perform some of the multi-scale modelling in which the finite element / control volume meshes are optimized to represent the physics. It is shown how errors in the overall solution can be calculated and how this approach can also be used to generate error measures to guide mesh adaptivity/numerical resolution.

As far as fluid-structure interaction modelling is concerned, the Finite Element Discrete Element Method (FEMDEM) is used for resolving the solids. FEM DEM is able to capture non-linear material behaviour and has multi-body and granular media capabilities so that sediment and scour can be modeled at the grain scale. The model Fluidity is used for the CFD. It is a multi-phase model based on arbitrary unstructured finite element meshes and has an anisotropic dynamic mesh adaptivity capability. This allows us to resolve highly complex geometries. 

We outline future research directions in multi-physics modelling, an approach to adaptive multi-scale modelling and how this may be linked to predictive modelling including uncertainty quantification, dataas simulation and reduced order, or rapid, modelling.
