SIAM Journal on Numerical Analysis , Abstract | PDF ( KB)Cited by: Navier-Stokes type problems is different from that in Chapters 2 and 3 e.g. nonlinear wave motion, cavitating flows, solidification and melting, metal casting, to name but a few. The present volume emerging as a viable alternative to finite difference and finite. pointwise constraint. The reliable and efficient numerical treatment is therefore challenging. We prove the convergence of a finite element discretization within the framework of $\Gamma$-convergence and discuss the convergence of an iterative solution method. The work is based on results by Friesecke, James, and M\"uller ().

We present a new finite volume version (, , ) of the 1-dimensional Lax-Friedrichs and Nessyahu-Tadmor schemes () for nonlinear hyperbolic equations on unstructured grids, and compare it to a recent discontinuous finite element method (, ) in the computation of some typical test problems for compressible flows. The book is divided into two parts. Part I is devoted to the most fundamental kinetic model: the Boltzmann equation of rarefied gas dynamics. Additionally, widely used numerical methods for the discretization of the Boltzmann equation are reviewed: the Monte--Carlo method, spectral methods, and finite-difference methods. AbstractIn this paper, a semi-discrete Galerkin finite element method is applied to the two-dimensional diffusive Peterlin viscoelastic model which can describe the unsteady behavior of some incompressible ploymeric fluids. For the derived semi-discrete finite element spatial discretization scheme, the a priori bounds are given that does not rely on the mesh width by: 2.
