Extreme-Scale Block-Structured Adaptive Mesh Refinement

In this article, we present a novel approach for block-structured adaptive mesh refinement (AMR) that is suitable for extreme-scale parallelism. All data structures are designed such that the size of the meta data in each distributed processor memory remains bounded independent of the processor number. In all stages of the AMR process, we use only distributed algorithms. No central resources su...

Cuda Parallelization of a 2-d Non-hydrostatic Compressible Atmospheric Model

Computational fluid dynamics in general require large computational resources. The same is true for an atmospheric model which simulates non-hydrostatic density-stratified flow with a gravity source term. There have been many applications of CUDA to CFD problems as can be seen by the many papers on . In fact, a full-scale global atmospheric model has been parallelized for CUDA. For my graduate ...

Simulating orographic rainfall with a limited-area, non-hydrostatic atmospheric model under idealized forcing

A modified version of an operational 3dimensional, non-hydrostatic, limited-area atmospheric model (MM5) was used to perform high-resolution, idealized simulations of the interaction of an infinitely long single ridge with a steady, lateral large-scale wind field. The effect of different mountain ridge dimensions, wind speeds and patterns and moisture profiles on the quantity and distribution o...

Common themes in multi-block structured quad/hex mesh generation

The automatic generation of structured multi-block quadrilateral (quad) and hexahedral (hex) meshes has been researched for many years without definitive success. The core problem in quad / hex mesh generation is the placement of mesh singularities to give the desired mesh orientation and distribution [1]. It is argued herein that existing approaches (medial axis, paving / plastering, cross / f...

Block-structured Adaptive Mesh Refinement - Theory, Implementation and Application

Structured adaptive mesh refinement (SAMR) techniques can enable cutting-edge simulations of problems governed by conservation laws. Focusing on the strictly hyperbolic case, these notes explain all algorithmic and mathematical details of a technically relevant implementation tailored for distributed memory computers. An overview of the background of commonly used finite volume discretizations ...
