Advanced Computing User Day

Matthias Möller

Matthias Möller is Associated Professor in the Department of Applied Mathematics at Delft University of Technology. His research focusses on numerical methods for the computational analysis and optimisation of problems that are modelled by partial differential equations (PDE). He is particularly interested in the combination of classical numerical methods with modern scientific machine learning techniques. A second pillar of his research is the development of quantum and quantum-inspired numerical methods for PDE analysis and optimization.

Computational steering: Interactive Design-through-Analysis in XR
Matthias Möller, Casper van Leeuwen

Interactive design-through-analysis workflows in XR to facilitate computational steering made possible by physics-informed ML, a low-barrier frontend and powerful compute system in the backend.

Computational steering has seen regular incarnations in the Computational Science and Engineering domain with every leap forward in computing and visualisation technologies. While often associated with the ability to interact with large-scale simulations running on remote high-performance compute clusters, this presentation will introduce novel interactive design-through-analysis techniques through visual demonstration with different modalities including XR devices.

The design-through-analysis paradigm means seamless integration of computer-aided design and simulation-based analysis tools so that scientists, engineers & researchers can go back and forth between product design, analysis, and optimisation.

The proposed approach's novelty consists of replacing traditional simulation-based analysis that often hinders rapid design-through-analysis workflows with our recently developed IgANets, which is the embedding of physics-informed machine learning into the Isogeometric Analysis paradigm. More precisely, we train parametrized deep networks to predict solution coefficients of B-Spline/NURBS representations in a compute-intensive offline stage. Problem configurations and geometries are encoded as B-Spline/NURBS objects and passed to the network as inputs, to provide a mechanism for user interaction. Evaluation of IgANets is instantaneous, thereby enabling interactive feedback loops.

In this presentation, we will present a first-of-its-kind demonstrator that couples IgANets, developed at the TU Delft, with a novel user frontend in XR, developed at SURF. Connected with this presentation is the wish to initiate a new trend in computational steering, interactive design-through-analysis.

When, How and for What to use quantum computers
Evert van Nieuwenburg, Matthias Möller, Nicolas Renaud, Allan Francis Beechinor, David Maier

Quantum science and technologies are rapidly developing and hold great potential to revolutionize numerous fields in academia and industry. As we progress, it is crucial to support education, awareness, and scientific curiosity in the topic. In this panel, we will discuss the current state of quantum computing and what this means for researchers interested in exploring and exploiting quantum technology.
