Finite Element Methods for Elliptic Equations Using Nonconforming Elements

A finite element method is developed for approximating the solution of the Dirichlet problem for the biharmonic operator, as a canonical example of a higher order elliptic boundary value problem. The solution is approximated by special choices of classes of discontinuous functions, piecewise polynomial functions, by virtue of a special variational formulation of the boundary value problem. The ...

Efficient Multigrid Solvers for the Stokes Equations using Finite Elements

Mixed nite element application to solve the Stokes equations using di erent smoothers by mean of multigrid technique has been investigated. Multigrid technique's e ciency for positive de nite linear systems is proved but it is much more challenging in the case of saddle-point problems. The e ciency of a multigrid method is highly dependent on the smoother and the coarse grid solver. A two-dimen...

Spectral Elements for Transport-Dominated Equations

Let's read! We will often find out this sentence everywhere. When still being a kid, mom used to order us to always read, so did the teacher. Some books are fully read in a week and we need the obligation to support reading. What about now? Do you still love reading? Is reading only for you who have obligation? Absolutely not! We here offer you a new book enPDFd spectral elements for transport ...

Computational Aeroacoustics: An Overview

An overview of recent advances in computational aeroacoustics (CAA) is presented. CAA algorithms must not be dispersive and dissipative. It should propagate waves supported by the Euler equations with the correct group velocities. Computation domains are inevitably finite in size. To avoid the reflection of acoustic and other outgoing waves at the boundaries of the computation domain, it is req...
