Digital Twin of the Notre-Dame Cathedral - Digital Modelling and Simulation Techniques as a Support for World Heritage Preservation
Dr. Vladimir Cerisano Kovačević, Kobe Innovation Engineering

Abstract: The problem of conservation for cultural heritage is continuously discussed in the field of restoration of damaged works of art and, ultimately, in the field of their digitalization. The conservation is then performed both in terms of concrete maintenance and in terms of digital transformation of data of interest: in this context, the recent dramatic event involving the Notre-Dame Cathedral in Paris has risen the question of Architectural Masterpieces preservation. This presentation gives an overview of the standard structural modelling techniques (FEM) applied on the Notre-Dame cathedral, transforming the complex architectural BIM (Building Information Model) virtual copy of the Church into an open source model. The result is a reliable support in evaluating its structural integrity by the means of different possible approaches, applicable on ancient masonry buildings, from highly non-linear and non-homogeneous behaviour hypothesis, to uncertainty quantification related to this kind of construction material.

Up the Down Staircase: Atomistic Modelling for Materials Science
Dr. Jacob Gavartin, Materials Science Lead at Schrödinger, Cambridge, United Kingdom

Abstract: Major advances in quantum chemistry and computational power brought about revolutionary changes in new materials discovery. This lecture will overview how the combination of atomistic simulations, automatic structure screening and machine learning reveal key relationships between chemical structure and critical physicochemical properties of materials. With the examples in electronics, composite materials and consumer goods and pharmaceutical formulations we discuss how quantum chemistry and molecular dynamics has evolved from largely academic domain into essential component of the industrial materials research. The second part of the talk will discuss the merits and challenges in so far elusive multiscale approaches connecting modelling at the atomic and engineering scales.

What is the economic value of a simulation? – How to strengthen the use simulation in product release
Dr. Martin Obermayr, Project manager in R&D projects, ZF Friedrichshafen AG, Germany

Abstract: Numerical simulation has become an elementary component of product development since the pioneering work in the field of finite element analysis in the 1960s.

While in the early phase of product development (the upper left branch of the V-model) the use of simulation methods has been established for quite some time, the use in the area of product verification and validation is still very limited.

In applications of high technical risks or prohibitive costs of testing, simulation has become a release-relevant part of product validation. An example is the aerospace industry.

On the other hand, in automotive industry physical tests still dominate product release to this day. Here, simulation plays a role primarily in product development, e.g. to support concept decisions and perform design optimizations - but hardly ever in the product release process.

In this paper, a procedure is shown that is neither purely based on simulation nor exclusively on physical tests, but rather a combination of both.

Predictions, coming from the simulation, are systematically compared with the observation in physical tests to come to a quantification of the simulation results in terms of reliability.

This reliability can then be applied as prior-knowledge in the reliability proof and reduce the experimental effort. In this way, the simulation results are given an economic value by saving tests. A hybrid release procedure is created.

A further aspect in this context is the model validation to gain the necessary confidence in the simulation models. To be able to use simulation for this procedure, it must be ensured that the results are always of the same quality. Credibility levels are presented, which state necessary demands on simulation models in order to be used for the hybrid release concept. The presentation is concluded with some examples for the application of this concept.

Electromagnetic Virtual Testing for Aircrafts: Towards Digitalization
Enrique Pascual Gil, Computational Electromagnetic Expert ,TEAYX-TL1 EME & Antenna Systems at Airbus Defence & Space

Abstract: Nowadays, most companies are changing their processes to a more digital model. Engineers have been digitizing since the beginning of the computer age by using computer simulations and models. This presentation is about virtual tests in electromagnetics as part of the digitalization process with a brief introduction to the discipline of computational electromagnetic engineering, its advantages and disadvantages and the development of this methodology in Airbus including some examples of use in our products.
