Beschreibung:

Particle methods like vortex methods or smoothed particle hydrodynamics are numerical schemes that are ideally suited for convection dominated flow problems. Unlike other mesh-based flow solvers, these methods do not suffer from numerical diffusion and have excellent conservation properties. One of the reasons why particle methods are so rarely used in practice today are their difficulties to accurately handle boundary conditions. In this talk we will first give a brief introduction to particle methods and try to illustrate their benefits. We then discuss some of the problems they are facing, with a focus on boundaries. We introduce and describe a new approach to the solution of one of these problems: particle regularisation.
