Leader of the group Scientific Computing: Daan Crommelin.

The SC groups develops efficient mathematical methods to simulate and predict real-world phenomena with inherent uncertainties. Such uncertainties arise from e.g. uncertain model parameters, chaotic dynamics or intrinsic randomness, and can have major impact on model outputs and predictions. Our work is targeted in particular at applications in climate, energy, finance and biology. In these vital areas, the ability to assess uncertainties and their impact on model predictions is of paramount importance. Expertise in the SC group includes uncertainty quantification, data assimilation, stochastic multiscale modeling and risk assessment. The availability of data to inform and improve simulations and predictions, for example through learning and data-driven modeling, plays an important role in our research.

Title: High-order structure-preserving splines for incompressible flow simulation

Abstract: In this talk, we will discuss the construction of high-order spline basis functions that span gradient, curl and divergence conforming spaces with applications to electromagnetism and fluid flows in mind. Stability of the resulting numerical schemes is complemented by pointwise satisfaction of conservation laws  — such as mass conservation in incompressible flow simulations — on arbitrarily curved geometries even at the coarsest levels of discretization. Examples demonstrating the robustness and applicability of the spline spaces will be presented. In particular, they will be used to simulate Stokes flow on curved surfaces that contain parameterization singularities.
