  1. 1. Smooth Particle Ribbons Through Hardware Accelerated Tessellation

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

    Author : Oliver Eriksson; [2022]
    Keywords : particles; tessellation; b-spline; mesh shaders;

    Abstract : Generating and rendering ribbons from a stream of particles is common in games and VFX to visualize flow. To create detailed smooth particle ribbons this work combines tessellation and B-splines, which gives smooth surfaces with contiguous normals. READ MORE

  3. 2. Time-Resolved Adaptive Finite Element Simulations for Building Aerodynamics : A proof of concept on minimal computational resources

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

    Author : Linde van Beers; [2021]
    Keywords : Building aerodynamics; Computational fluid dynamics; Wind engineering; FEniCS; Adaptive mesh refinement; Atmospheric boundary layer; Direct finite element simulation; Byggnadsaerodynamik; Beräkningsströmningsdynamik; Vindteknik; FEniCS; Adaptiv nätförfining; Atmosfäriskt gränsskikt; Direkt finita elementsimulering;

    Abstract : The effect of building geometry on the wind environment of cities is such that it can cause problems like wind danger, discomfort and poor ventilation of airborne pollutants. Computational fluid dynamics (CFD) can play a role in assessing changes in wind environment caused by building projects before realisation at little cost. READ MORE

  4. 3. An Adaptive Surface Finite Element Method for the Laplace-Beltrami Equation

    University essay from KTH/Numerisk analys, NA

    Author : Gökce Tuba Masur; [2017]
    Keywords : ;

    Abstract : In this thesis, we present an adaptive surface finite element method for the Laplace-Beltrami equation. The equation is known as the manifold equivalent of the Laplace equation. READ MORE

  5. 4. A comparison of two multilevel Schur preconditioners for adaptive FEM

    University essay from Avdelningen för beräkningsvetenskap

    Author : Christian Karlsson; [2014]
    Keywords : computational science; PDE; partial differential equations; FEM; finite element method; adaptive mesh refinement; Schur complement; multilevel method; iterative method; conjugate gradient method; beräkningsvetenskap; PDE; partiella differentialekvationer; FEM; finita elementmetoden; adaptivt beräkningsnät; adaptiv mesh; Schurkomplement; multilevelmetod; iterativ metod; konjugerade gradientmetoden;

    Abstract : There are several algorithms for solving the linear system of equations that arise from the finite element method with linear or near-linear computational complexity. One way is to find an approximation of the stiffness matrix that is such that it can be used in a preconditioned conjugate residual method, that is, a preconditioner to the stiffness matrix.

  6. 5. High performance adaptive finite elementmodeling of complex CAD geometry

    University essay from KTH/Numerisk analys, NA

    Author : Stefanie Strunk; [2013]
    Keywords : ;

    Abstract : CAD (Computer Aided Design) and finite elementanalysis are of fundamental importance for numerical simulations. The generalapproach is to design a model using CAD software, create a mesh of a domainthat includes this model and use finite element analysis to perform simulationson that mesh. READ MORE
