Hierarchical Preconditioning for <i>P</i><sup><i>T</i></sup><i>AP</i>‐Systems arising from particulate flows
Abstrak
AbstractParticulate flows, i.e. flow of an incompressible, Newtonian carrier fluid loaded with (many) rigid bodies, play an important role in diverse technical applications. In [1] a finite element method was introduced to simulate such flows. The method relies on a splitting method and a subspace projection method to incorporate the rigid body motion of the particles in a so called one domain approach [2]. The resulting systems arising after discretization are ill conditioned in general. Thus preconditioning is mandatory for instance when using an iterative Krylov subspace methods. In this paper we present a Schur complement based preconditioner well suited for this type of application. (© 2012 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
