Deflation in preconditioned conjugate gradient methods for Finite Element Problems

Vermolen, F.J. (author), Vuik, C. (author), Segal, A. (author)

We investigate the influence of the value of deflation vectors at interfaces on the rate of convergence of preconditioned conjugate gradient methods applied to a Finite Element discretization for an elliptic equation. Our set-up is a Poisson problem in two dimensions with continuous or discontinuous coefficients that vary in several orders of...

A mass conserving level set (MCLS) method for modeling of multi-phase flows

Van der Pijl, S.P. (author), Segal, A. (author), Vuik, C. (author)

The Mass-Conserving Level-Set (MCLS) method is proposed to model multi-phase flows. The aim is to model high density-ratio flows with complex interface topologies, such as mixtures of bubbles and droplets. Aspects which are taken into account are: a sharp front (density changes rapidly), arbitrary shaped interfaces, surface tension, buoyancy and...

A level set method for particle dissolution in a binary alloy

Javierre, E. (author), Vuik, C. (author), Vermolen, F.J. (author), Segal, A. (author)

A mathematical model is proposed for the dissolution of stoichiometric particles in binary alloys occurring during the heat treatments of as-cast aluminium alloys prior to hot extrusion. The Level Set method is used to capture the interface location implicitly. The front velocity, only dened on the moving interface, should be advected to the...

Finite-element model for phase-change recording

Brusche, J.H. (author), Segal, A. (author), Urbach, H.P. (author)

The finite-element method is applied to model phase-change recording in a grooved recording stack. A rigorous model for the scattering of a three-dimensional focused spot by a one-dimensional periodic grating is used to determine the absorbed light in a three-dimensional region inside the phase-change layer. The optical model is combined with a...

Solution of the incompressible Navier Stokes equations with preconditioned Krylov subspace methods

Ur Rehman, M. (author), Vuik, C. (author), Segal, G. (author)

In this report, using SEPRAN, the incompressible Stokes and Navier Stokes problems are solved in a square and L-shaped domain with a varying grid size and Reynolds number. Both problems are solved with iterative solvers using an ILU preconditioner. Different ordering techniques of the grid points and the unknowns are used to avoid breakdown of...

Modeling of three-dimensional multi-phase flows with a mass-Conserving Level-Set method

van der Pijl, S.P. (author), Segal, A. (author), Vuik, C. (author)

In this work incompressible two-phase flows are considered. The aim is to model high density-ratio flows with arbitrary complex interface topologies, such as occur in air/water flows. Between the phases a sharp front exists, where density and viscosity change abruptly. The computational method used in this paper is the Mass Conserving Level-Set...
