Papers Repository of the International Centre for Numerical Methods in Engineering (CIMNE) The challenge of mass conservation in the solution of free‐surface flows with the fractional‐step method: Problems and solutions

Abstract

The purpose of this paper is to put in evidence that the fractional‐step method (FSM) used to solve the incompressible transient Euler and Navier–Stokes equations for free‐surface [...]

Papers Repository of the International Centre for Numerical Methods in Engineering (CIMNE) A domain decomposition strategy for reduced order models. Application to the incompressible Navier–Stokes equations

Abstract

In this work, a domain decomposition strategy for non-linear hyper-reduced-order models is presented. The basic idea consists of restricting the reduced-order basis functions to the nodes [...]

Journal's Papers Objectivity tests for Navier–Stokes simulations: The revealing of non-physical solutions produced by Laplace formulations

Abstract

Laplace formulations are weak formulations of the Navier–Stokes equations commonly used in computational fluid dynamics. In these schemes, the viscous terms are given as a function [...]

Papers Repository of the International Centre for Numerical Methods in Engineering (CIMNE) The violation of objectivity in Laplace formulations of the Navier–Stokes equations

Abstract

The Navier–Stokes equations written in Laplace form are often the starting point of many numerical methods for the simulation of viscous flows. Imposing the natural boundary conditions [...]
