"GPU Accelerated Tsunami Modeling With Real-Time Rendering"

Predicting tsunamis has become of great importance in disaster prevention as they are one of the deadliest forces evoked by nature. The propagating waves like tsunamis, are often modeled by the Shallow Water Equations (SWE), under some assumptions. SWE are 2D hyperbolic PDEs and in order to simulate the solution with high precision, we use high order nodal discontinuous Galerkin methods. More specifically, we tailor these algorithms to suit the GPU parallel architecture for high throughput and take advantage of the hardware to produce real-time solution rendering.

Apart from the algorithm, we will discuss the meshing utility created for this project and how the real-time visualization was produced without the storage of output files traditionally used in the post-processing step.
