  1. 11. Implementation of a standard level set method for incompressible two-phase flow simulations

    University essay from Avdelningen för teknisk databehandling

    Author : Niklas Johansson; [2011]
    Keywords : level set method; incompressible two-phase flow; reinitialization; finite element method; deal.II;

    Abstract : The level set method is a powerful way of tracking surfaces by defining the surface as a zero level set of a continuous function that is usually a signed distance function. The level set method is one of the best methods for simulating multi-phase flow because it can easily handle fast topological changes, as well as splitting and merging of fluids. READ MORE

  3. 12. Efficient implementation of the Particle Level Set method

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : John Johansson; [2010]
    Keywords : Computational fluid dynamics; Deformable surfaces; Implicit surfaces; Level set methods;

    Abstract : The Particle Level set method is a successful extension to Level set methods to improve thevolume preservation in fluid simulations. This thesis will analyze how sparse volume data structures can be used to store both the signed distance function and the particles in order to improve access speed and memory efficiency. READ MORE
