  • Hybrid Smoothed Particle Hydrodynamics This is the accompanying video for the paper presented at the Symposium of Computer Animation (SCA 2011): Hybrid Smoothed Particle Hydrodynamics, Karthik Raveendran, Chris Wojtan, Greg Turk Project: By combining a pressure projection on a coarse Eulerian grid with SPH, we can take larger timesteps and maintain near uniform particle density. This method is 2-4x faster than typical SPH simulators without exhibiting noticeable compression artifacts.

  • Hydraulic Erosion Using Smoothed Particle Hydrodynamics Kristof, P., Benes, B., Krivanek, J., & Stava, O. This paper presents a new technique for modification of 3D terrains by hydraulic erosion. It efficiently couples fluid simulation using a Lagrangian approach, namely the Smoothed Particle Hydrodynamics (SPH) method, and a physically-based erosion model adopted from an Eulerian approach. The eroded sediment is associated with the SPH particles and is advected both implicitly, due to the particle motion, and explicitly, through an additional velocity field, which accounts for the sediment transfer between the particles. We propose a new donor-acceptor scheme for the explicit advection in SPH. Boundary particles associated to the terrain are used to mediate sediment exchange between the SPH particles and the terrain itself. Our results show that this particle-based method is efficient for the erosion of dense, large, and sparse fluid. Our implementation provides interactive results for scenes with up to 25000 particles.

  • Two Log Pontoon hydrodynamics, ventilation & wake characteristics at various speeds My endeavor to catalog and video typical hydrodynamics seen in Pontoon Operation. Benefits: 1. Why BIG FOOT gearcases exist 2. Why Ventilation in turns occurs 3. Why Performance Strakes, Specialized Nose Cones and Spray shields vary, along with Underdeck Skins. It will also illustrate that a mere 5 mph difference is quite a difference! This first video installment is: (2) two-log Pontoon Boat operation. Video endeavors to show 0 mph, 5 mph, 10 mph, 15 mph & 20 mph shots, with detailed speed variations that focus on cone design, cone spray shield, and motor pod design. (Test vehicle was a 20ft pontoon boat with 25inch logs, no Performance Strakes, No Underbelly "WaveTamer" skin, a pretty common pontoon design in 2011) Our next video installments will show two-log pontoons with WaveTamer and Performance Strakes, and even later a triple-log tri-toon operation, and how they vary in spray and turbulence. We hope that the audience will observe and recognize that pontoons, unlike V-Hull boats, squeeze the water and spray inward. This causes a great deal of turbulence. So a motor must reach down deeper into the water to escape the aerated water, or it is forced to ventilate in the aeration. Moreover, higher speeds above 15mph begin to benefit from lifting strakes and underbelly skin. Even there, we'll endeavor to show the differences in design, cause & effect between strakes and WaveTamer underbelly skin.

  • Eonfusion flood modelling using smoothed-particle hydrodynamics Eonfusion's multi dimensional data structure model and customised flood module have been tailored to modelling the hydrodynamics of flood waters and the process of inundation. The flood module leverages GPU technology to model and capture the trajectories of millions of smoothed-particles added by the user in the interactive real-time model environment. Model results can be visualised as the particle trajectories or summarised in time varying (3D) rasters containing water depth, velocity and heading. The use of GPU technology and the ability to handle several hundred million data records at one time allows Eonfusion to effectively model flood water dynamics and integrate important contextual data for a holistic view.
  • Project Torpedalo - Final Hydrodynamics Test The third and final hydrodynamics test at Newcastle University's MAST towing tank. The aims of the test were to evaluate the drag curve of the now finished hull shape, determine the drag induced by the drivetrain(s) and collect some data to help decide on rudder size. It was also a good chance to test our waterproof video camera! This work wouldn't have been possible without the unwavering support of John Burn Ltd, CGI, Bentley Motors and Newcastle University. Thanks to all those who have made this testing a success. We're still crunching through the data, but the numbers are looking very, very good!

  • Pontoon Hydrodynamics with Aluminum Underdeck Skin - Turbulence Variation #1 In this installment, we have added a 0.062" aluminum skin to the underdeck. There was no speed gain, the boat is capable of 25 mph on GPS with 90 hp Engine. The boat ride comfort improves as a just-discernable vibration is removed from the entire boat by the addition of skin. Note: It took speeds of over 15 mph to produce sufficient spray to warranty the skin. No speed gain was observed, but a higher comfort level was attained. Our next installment will be a 22ft two-log pontoon with no underdeck skin but with the addition of performance strakes.

  • The Hydrodynamics of Wine Swirling A crucial step in wine tasting is the so called swirling, necessary to release the bouquet of the wine: a gentle circular movement of the glass generates a wave propagating along the glass walls, enhancing oxygenation and mixing. Although being used in a large variety of other applications (eg cells cultures in orbital shaken bioreactors) this motion is not yet well understood. In this fluid dynamics video we show the large variety of waves shapes generated by this simple movement, and we identify a group of dimensionless parameters governing the flow.

  • Dwarf galaxy formation by hydrodynamical SPH simulations From the paper "Bulgeless dwarf galaxies and dark matter cores from supernova-driven outflows," by F. Governato, C. Brook, L. Mayer, A. Brooks, G. Rhee, J. Wadsley, P. Jonsson, B. Willman, G. Stinson, T. Quinn & P. Madau. Nature 13 january 2010. The properties of 'dwarf' galaxies have long challenged the cold dark matter (CDM) model of galaxy formation, as the properties of most observed dwarf galaxies contrast with models based on the dominance of CDM. Here, hydrodynamical simulations (assuming the presence of CDM) are reported in which the ***ogues of dwarf galaxies — bulgeless and with shallow central dark-matter profiles — arise naturally. The movie is from computer simulations using SPH Treecode Gasoline. A fully parallel, N-body+smoothed particle hydrodynamics (SPH) code GASOLINE is used to compute the evolution of both the collisionless and dissipative component in the simulations. A detailed description of the code is available in the literature. Here we recall its essential features. GASOLINE computes gravitational forces using a treecode that employs multipole expansions to approximate the gravitational acceleration on each particle. A tree is built with each node storing its multipole moments. Time integration is carried out using the leapfrog method, which is a second-order symplectic integrator requiring only one costly force evaluation per timestep and only one copy of the physical state of the system. In cosmological simulations periodic ...
  • Smoothed Particle Hydrodynamics 3 : Assignment Final Scene 1 This is the first scene from a simple CUDA implementation of SPH using simple "bucket" grid to speed up queries. The wall provides a tangential force in order to keep motion going. Adjusting viscosity too high will produce instability as shown. Since this makes only a single density estimation, a high rest density setting will tend to coalesce into local globules. (Actually these grouping tend to occur at the grid sites. To do.) Based on the paper by Takahiro Harada of Tokyo University.

  • Modeling Early Galaxies Using Radiation Hydrodynamics This simulation uses a flux-limited diffusion solver to explore the radiation hydrodynamics of early galaxies, in particular, the ionizing radiation created by Population III stars. At the time of this rendering, the simulation has evolved to a redshift of 3.5. The simulation volume is 11.2 comoving megaparsecs, and has a uniform grid of 10243 cells, with over 1 billion dark matter and star particles. This animation shows a combined view of the baryon density, dark matter density, radiation energy and emissivity from this simulation. The multi-variate rendering is particularly useful because is shows both the baryonic matter ("normal") and dark matter, and the pressure and temperature variables are properties of only the baryonic matter. Visible in the gas density are "bubbles", or shells, created by the radiation feedback from young stars. Seeing the bubbles from feedback provides confirmation of the physics model implemented. Features such as these are difficult to identify algorithmically, but easily found when viewing the visualization. Simulation was performed on Kraken at the National Institute for Computational Sciences. Visualization was produced using resources of the Argonne Leadership Computing Facility at Argonne National Laboratory.
