  1. 1. Numerical solutions to the incompressible Navier-Stokes equations : Finite difference solutions in curvilinear coordinates

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : David Niemelä; [2022]
    Keywords : ;

    Abstract : A finite difference scheme for the incompressible Navier-Stokes equations in 2-dimensionalcurvilinear coordinates is derived. The scheme uses high-order Summation-By-Parts operatorsand boundaries are handled by the Projection method. READ MORE

  3. 2. Numerical simulations of the Dynamic Beam Equation in discontinuous media

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Niklas Wik; David Niemelä; Valter Wagner Zethrin; [2020]
    Keywords : Dynamic beam equation; DBE; SAT; projection; SBP;

    Abstract : The study examines the Projection method and the simultaneousapproximation-term (SAT) method as boundary treatment for the dynamic beam equation using summation-by-parts (SBP) operators for handling the inner domain. The methods are examined for both the homogeneous constant coefficient case, and the inhomogeneous piecewise constant coefficient case with a coupled interface. READ MORE
