Wavelet-based adaptive mesh refinement on the GPU for shallow water modelling

  title={Wavelet-based adaptive mesh refinement on the GPU for shallow water modelling},
  author={Alovya Ahmed Chowdhury and Georges Kesserwani and Charles Roug'e and Paul Richmond},
Wavelet-based adaptive mesh refinement (AMR) uses a rigorous “multiresolution analysis” (MRA) to construct a robust, inherently adaptive numerical solution. Despite its rigour however, there is no parallel implementation of wavelet-based AMR on graphics processing units (GPU) for shallow water modelling since the MRA is recursive and therefore inherently sequential. This paper reworks the recursive nature of MRA into a form suitable for parallelisation by simultaneously adopting two ingredients… 



Efficient GPU-Implementation of Adaptive Mesh Refinement for the Shallow-Water Equations

This work presents the first full GPU-implementation of a block-based AMR method for the second-order Kurganov–Petrova central scheme and believes it is transferable to other hyperbolic conservation laws, numerical schemes, and architectures similar to the GPU.

An adaptive moving finite volume scheme for modeling flood inundation over dry and complex topography

A new geometrical conservative interpolation on unstructured meshes is developed for preserving still water equilibrium and positivity of water depth at each iteration of mesh movement, leading to an

GPU implementation of the 2D shallow water equations for the simulation of rainfall/runoff events

This work deals with an efficient GPU implementation of the 2D shallow water equations on unstructured meshes analysing the influence of the mesh resolution both on the computational performance and the quality of the results to simulate a rainfall/runoff event.

Parallelisation of Multiscale-Based Grid Adaptation using Space-Filling Curves

In order to perform 3D computations for complex geometries in reasonable CPU time, the underlying multiscale-based grid adaptation strategy has to be parallelised via MPI for distributed memory architectures and this has been realised using space-lling curves.
