    Finite calculus. A stabilized finite element method for solving the Navier-Stokes equations. Application to ocean turbulence 

    Lamorena German, Arnel (Fecha de defensa: 2020-09-17)

    Ocean turbulence is a classic example of turbulent motion and observations of turbulence in the ocean lack in regions of complex topography since in-situ and experimental data are complicated to obtain. As a result, ocean ...

    High-order hybridizable discontinuous Galerkin formulation and implicit Runge-Kutta schemes for multiphase flow through porous media 

    Costa Solé, Albert (Fecha de defensa: 2020-07-17)

    This dissertation presents high-order hybridisable discontinuous Galerkin (HDG) formulations coupled with implicit Runge-Kutta (RK) methods for the simulation of one-phase flow and two-phase flow problems. High-order-methods ...

    Large-scale tree-based unfitted finite elements for metal additive manufacturing 

    Miranda Neiva, Eric (Fecha de defensa: 2020-10-07)

    This thesis addresses large-scale numerical simulations of partial differential equations posed on evolving geometries. Our target application is the simulation of metal additive manufacturing (or 3D printing) with powder-bed ...
