Finite Element Simulations of Two-phase Flow and Floating Bodies Using FEniCS-HPC
(2018-07)
We present a variational multiscale stabilized finite element method to solve the variable density incompressible Navier-Stokes equations for the simulation of two-phase flow. We introduce a level-set method based on the ...
A partition of unity finite element method for computational diffusion MRI
(2018)
The Bloch–Torrey equation describes the evolution of the spin (usually water proton)
magnetization under the influence of applied magnetic field gradients and is commonly
used in numerical simulations for diffusion MRI ...
Variational multiscale stabilization for compressible flow
(2018)
This paper presents a variational multiscale stabilization for the finite element numerical solution of the Euler and Navier-Stokes equations of compressible flow. All the components of the dual operator are considered in ...
Nonlinear computations of heave motions for a generic Wave Energy Converter
(2018)
A bench-marking activity of numerical methods for analysis of Wave Energy Converters (WEC) was proposed under the Ocean Energy Systems (OES) International Energy Agency (IEA) Task 10 in 2015. The purpose of the benchmark ...
Time-resolved Adaptive Direct FEM Simulation of High-lift Aircraft Configurations
(2017-08-01)
Our simulation methodology is referred to as Direct FEM Simulation (DFS), or General Galerkin (G2) and uses a finite element method (FEM) with piecewise linear approximation in space and time, and with numerical stabilization ...
Towards HPC-Embedded Case Study: Kalray and Message-Passing on NoC
(2017)
Today one of the most important challenges in HPC is the development of computers with a low power consumption. In this context, recently, new embedded many-core systems have emerged. One of them is Kalray. Unlike other ...
Direct finite element simulation of turbulent flow for marine based renewable energy
(2017)
In this article we present a computational framework for simulation of
turbulent flow in marine based renewable energy applications. In
particular, we focus on floating structures and rotating
turbines. This work is an ...
Multipreconditioned GMRES for Shifted Systems
(2017-01-01)
An implementation of GMRES with multiple preconditioners (MPGMRES) is proposed for solving shifted linear systems with shift-and-invert preconditioners. With this type of preconditioner, the Krylov subspace can be built ...
