Evaluation and adaption of the SPH method for hydraulic engineering problems on federal waterways

E. Rustico and J. A. Jankowski

BAW internal R&D-project report, 2010-2016.

Abstract: Smoothed Particle Hydrodynamics (SPH) is a Lagrangian method for fluid dynamic simulations. In the past decades it drew the attention of the scientific community for its versatility and the possibility to simulate complex phenomena such as e.g. surface tension and fluid-solid interactions with floating objects. SPH has in general higher computational requirements than the most common Eulerian methods and several different models have been proposed for the treatment of boundaries, each with advantages and limitations.

A hardware-accelerated parallel implementation of a two-dimensional scheme for free surface flows

J.A. Jankowski

Abstract: This contribution concerns the verification and performance assessment of a hardware-accelerated parallel implementation of an algorithm for the semi-implicit finite difference method for solving the vertically integrated shallow water equations including a non-linear treatment of wetting and drying and conservative advection schemes.

Short info: GPU version of the 2Dxy scheme

Short info: GPU version of the 2Dxy scheme, 9th UnTRIM Workshop, Trento, 7-9 May 2012.

The ongoing developments of the GPU-implementation of the 2Dxy semi-implicit scheme for general free surface flows. Moving towards a generic application by providing a user interface and embedding the CUDA computational core in C++ structures, as well as code verification and validation. Continue reading

General-purpose GPUs – why interesting?

Jacek A. Jankowski. General-purpose GPUs – why interesting?, 7th UnTRIM Workshop, Trento, 3-5 May 2010.

The philosophy behind the general purpose GPU computing with arguments pro and against is discussed with the background of initiated projects to adapt specific numeric schemes to apply this technology. Continue reading
