Multigrid method for a vortex breakdown simulation

Numerical Simulation of Vortex Breakdown by the Vortex-Filament Method

Review of Vortex Methods for Simulation of Vortex Breakdown

The aim of this work is to identify current developments in the field of vortex breakdown modelling in order to initiate the development of a numerical model for the simulation of F/A-18 empennage buffet. Some attempts at using vortex models for prediction of vortex breakdown were found in the open literature. Their advantages and shortcomings are discussed, allowing the evaluation of their fea...

An adaptive continuation-multigrid method for the balanced vortex model

Obtaining solutions of the Eliassen balanced vortex model requires solving an invertibility relation, which is a nonlinear elliptic problem of the MongeAmpere type. Multigrid techniques for this problem are investigated. An adaptive algorithm which combines the full multigrid method with continuation in a parameter related to the strength of the forcing is developed. Numerical results demonstra...

A physically faithful multigrid method for fast cloth simulation

We present an efficient multigrid algorithm that is adequate to solve a heavy linear system given in cloth simulation. Although multigrid has been successfully applied to the Poisson problems, it is hard to migrate to complicated cloth deformations due to its lack of physical meaning in level construction. We addresses this problem by developing a physically faithful technique ensuring the cons...
