Adaptive simulation of unsteady flow past the submerged part of a floating wind turbine platform
(2015-12-31)Offshore floating platforms for wind turbines represent challenging concepts for designers trying to combine an optimal compromise between cost effectiveness and performance. Modelling of the hydrodynamic behaviour of the ... -
Direct FEM large scale computation of turbulent multiphase flow in urban water systems and marine energy
(2016-11-30)High-Reynolds number turbulent incompressible multiphase flow represents a large class of engineering problems of key relevance to society. Here we describe our work on modeling two such problems: 1. The Consorcio de Aguas ... -
FEniCS-HPC: Automated predictive high-performance finite element computing with applications in aerodynamics
(2016-01-01)Developing multiphysics finite element methods (FEM) and scalable HPC implementations can be very challenging in terms of software complexity and performance, even more so with the addition of goal-oriented adaptive mesh ... -
On the Relationship between the One-Corner Problem and the $M-$Corner Problem for the Vortex Filament Equation
(2018-06-28)In this paper, we give evidence that the evolution of the vortex filament equation (VFE) for a regular M-corner polygon as initial datum can be explained at infinitesimal times as the superposition of M one-corner initial ... -
One-dimensional chaos in a system with dry friction: analytical approach
(2015-12-31)We introduce a new analytical method, which allows to find chaotic regimes in non-smooth dynamical systems. A simple mechanical system consisting of a mass and a dry friction element is considered. The corresponding ... -
Turbulence and fire-spotting effects into wild-land fire simulators
(2016-01-01)This paper presents a mathematical approach to model the effects and the role of phenomena with random nature such as turbulence and fire-spotting into the existing wildfire simulators. The formulation proposes that the ...
