  1. 1. Comparison between Smoothed-Particle Hydrodynamics and Position Based Dynamics for real-time water simulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rasmus Andersson; Erica Tjernell; [2023]
    Keywords : Fluid simulation; Lagrangian fluid simulation; Smoothed-Particle Hydronamics; Position Based Dynamics; Vätskesimulering; Lagransk vätskesimulering; Smoothed-Particle Hydronamics; Position Based Dynamics;

    Abstract : Two of the methods common in video game fluid simulation are SmoothedParticle Hydrodynamics (SPH), and Position Based Dynamics (PBD). They are both Lagrangian methods of fluid simulation. SPH has been used for many years in offline simulations and has truthful visuals, but is not as stable as the newer method PBD when using larger timesteps. READ MORE

  3. 2. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Josep Plana Riu; [2022]
    Keywords : ;

    Abstract : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. READ MORE

  4. 3. Stellar Encounters at the Galactic Centre

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Roberts Fisers; [2022]
    Keywords : Galaxy; encounter; SPH; NSC; Physics and Astronomy;

    Abstract : Using methods of smoothed particle hydrodynamics (SPH) an N -body simulation was set-up to investigate stellar encounters between a 1 solar-mass main sequence (MS) star, modeled after the Sun, and a 0.6 solar-mass white dwarf (WD). This was done primarily to investigate the assumptions made by Mastrobuono-Battisti et al. READ MORE

  5. 4. Asymmetries in shaped charges

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gustav Boman; [2021]
    Keywords : ;

    Abstract : This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shock­compression results in a jetof metal being shot forward in up 10km/s. READ MORE

  6. 5. Slab and Powder-Snow avalanche animation on the GPU

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Åleskog Jonthan; Cheh Daniel; [2021]
    Keywords : Avalanche; GPU; DEM; Real-time; Games; Lavin; GPU; DEM; Realtid; Spel;

    Abstract : Background: The video game industry has yet to achieve a physically-based real-time avalanche simulation because of the sheer complexity of modeling the behavior of snow avalanches. An avalanche is made out of snow, meaning it would require a snow simulation which itself already shows to be complex. READ MORE
