A comparative study of earthquake source models in high-order accurate tsunami simulations

Published in Ocean Modelling, 2019

This paper is about different tsunami source models. We study the impact of dynamic and static source models on the numerical results obtained with them. This is done using our discontinuous Galerkin method. Numerical results are comnpared to real-world data such as satellite and buoy measurements.

Generating Liquid Simulations with Deformation-aware Neural Networks

Published in International Conference on Learning Representations, 2018

This publication proposes a method of using neural networks to generate liquid simulations on the fly. Space-time datasets are used to learn deformation networks which can reconstruct a new space-time dataset that the network is fed. We demonstrate the effectiveness of the method, by doing this on a smartphone in real-time.

Discontinuous Galerkin scheme for the spherical shallow water equations with applications to tsunami modeling and prediction

Published in Journal of Computational Physics, 2018

This paper is about Tsunami simulations using a Discontinuous Galerkin method for the Spherical Shallow Water Equations. We present a method that is well-balanced even when wetting-drying and dynamically adaptive meshing is considered. We demonstrate this using large-scale tsunami simulations such as the 2011 Tohoku tsunami. Results are compared to real-world measurements.
