Modelling, Analysis and Simulation Modelling, Analysis and Simulation An Unstructured Parallel Least-Squares Spectral Element Solver for Incompressible Flow Problems
The parallelization of the least-squares spectral element formulation of the Stokes problem has recently been discussed for incompressible flow problems on structured grids. In the present work, the extension to unstructured grids is discussed. It will be shown that, to obtain an efficient and scalable method, two different kinds of distribution of data are required involving a rather complicat...
متن کاملH- and P- Adaptive Incompressible Flow Solutions on Cartesian Grids Using Least Squares Spectral Element Method
Use of numerical solutions to flow phenomena has become increasingly common among non-engineering disciplines such as medical sciences. This increasing interest can be promoted by the ability of solvers to obtain accurate numerical solutions without the need for expertise in some specific subjects such as grid generation or automatic grid adaptation. In this work, an incompressible flow solver ...

متن کاملIncompressible laminar flow computations by an upwind least-squares meshless method
In this paper, the laminar incompressible flow equations are solved by an upwind least-squares meshless method. Due to the difficulties in generating quality meshes, particularly in complex geometries, a meshless method is increasingly used as a new numerical tool. The meshless methods only use clouds of nodes to influence the domain of every node. Thus, they do not require the nodes to be conn...
متن کاملNumerical Solution of Incompressible Cahn-Hilliard and Navier-Stokes System with Large Density and Viscosity Ratio Using the Least-Squares Spectral Element Method
There is a growing interest in numerically handling of the interface dynamics in multiphase flows with large density and viscosity ratio in several scientific and engineering applications. We present a parallel space-time implementation of a least-squares spectral element method for the incompressible Cahn-Hilliard and Navier-Stokes equations for different densities and viscosities between phas...
