Energy and maximum norm estimates for nonlinear conservation laws by P Olsson( Book )

4 editions published in 1994 in English and held by 80 WorldCat member libraries worldwide

Abstract: "We have devised a technique that makes it possible to obtain energy estimates for initial-boundary value problems for nonlinear conservation laws. The two major tools to achieve the energy estimates are a certain splitting of the flux vector derivative f(u)[subscript x], and a structural hypothesis, referred to as a cone condition, on the flux vector f(u). These hypotheses are fulfilled for many equations that occur in practice, such as the Euler equations of gas dynamics. It should be noted that the energy estimates are obtained without any assumptions on the gradient of the solution u. The results extend to weak solutions that are obtained as pointwise limits of vanishing viscosity solutions. As a by-product we obtain explicit expressions for the entropy function and the entropy flux of symmetrizable systems of conservation laws. Under certain circumstances the proposed technique can be applied repeatedly so as to yield estimates in the maximum norm."

Methods for the approximate solution of time dependent problems by H Kreiss( Book )

11 editions published between 1973 and 1994 in English and held by 78 WorldCat member libraries worldwide

The research dealt with computing methods for applications in aerodynamics, geophysics, hydrodynamics, meteorology, and oceanography. Analysis was done of adaptive numerical methods for time-dependent problems in complicated physical domains which can efficiently and reliably approximate singular and near singular features of the solution such as fronts and shocks. Work focused on development of algorithms which could be executed on parallel architectures and upon data structures and language constructs which allow this to be done efficiently and effectively
Stability and error estimation for component adaptive grid methods by Joseph Oliger( Book )

4 editions published in 1994 in English and held by 76 WorldCat member libraries worldwide

Abstract: "Component adaptive grid (CAG) methods for solving hyperbolic partial differential equations (PDE's) are discussed in this paper. Applying recent stability results for a class of numerical methods on uniform grids, the convergence of these methods for linear problems on component adaptive grids is established here. Furthermore, the computational error can be estimated on CAG's using the stability results. Using these estimates, the error can be controlled on CAG's. Thus, the solution can be computed efficiently on CAG's within a given error tolerance. Computational results for time dependent linear problems in one and two space dimensions are presented."

Theoretical and practical aspects of some initial-boundary value problems in fluid dynamics by Joseph Oliger( Book )

8 editions published in 1976 in English and Undetermined and held by 8 WorldCat member libraries worldwide

Initial-boundary value problems for several systems of partial differential equations from fluid dynamics are discussed. Both rigid wall and open boundary problems are treated. Boundary conditions are formulated and shown to yield well-posed problems for the Eulerian equations for gas dynamics, the shallow-water equations, and linearized constant coefficient versions of the incompressible, anelastic equations. The primitive hydrostatic meteorological equations are shown to be ill-posed with any specification of local, pointwise boundary conditions. Analysis of simplified versions of this system illustrates the mechanism responsible for ill-posedness. (Author)
Stability of the Fourier method by H Kreiss( Book )

This paper develops a stability theory for the Fourier (or pseudospectral) method for linear hyperbolic and parabolic partial differential equations with variable coefficients
Control of the dissipativity of Lax-Wendroff type methods for first order systems of hyperbolic equations by Tony F Chan( Book )

6 editions published in 1977 in English and Undetermined and held by 7 WorldCat member libraries worldwide

Lax-Wendroff methods for hyperbolic systems have two characteristics which are sometimes troublesome. They are sometimes too dissipative--they may smooth the solution excessively--and their dissipative behavior does not affect all modes of the solution equally. Both of these difficulties can be remedied by adding properly chosen accretive terms. We develop modifications of the Lax-Wendroff method which equilibrate the dissipativity over the fundamental modes of the solution and allow the magnitude of the dissipation to be controlled. We show that these methods are stable for the mixed initial boundary value problem and develop analogous formulations for the two-step Lax-Wendroff and MacCormack methods. (Author)

Adaptive grid refinement for numerical weather prediction by William C Skamarock( Book )

3 editions published in 1987 in English and held by 3 WorldCat member libraries worldwide

An adaptive atmospheric flow model is described and results of integrations with this model are presented. The adaptive technique employed is that of Berger and Oliger. The technique uses a finite difference method to integrate the dynamical equations first on a cargo grid and then on finer grids which have been placed based on a Richardson type estimate of the truncation error in the coarse grid solution. By correctly coupling the integrations on the various grids, periodically reestimating the error nad recreating the finer grids, uniformly accurate solutions are economically producted. The primitive hydrostatic equations of meteorology are solved for the advection of a barotropic cyclone and for the development of a baroclinic disturbance which results from the perturbation of an unstable jet. These integrations demonstrate the feasibility of using multiple, rotated, overlapping fine grids. Direct computations of the truncation error are used to confirm the accuracy of the Richardson type truncation error estimates

Adaptive Component Methods for Time Dependent PDE's by Stanford University( Book )

2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide

Component adaptive grid methods for the solution of time dependent partial differential equations are described. These methods allow one to solve problems in complicated regions efficiently and accurately, to automatically control the accuracy of the results obtained and provide a simple user interface. The use of a graphical editing system, VOUS, for grid generation and program development and of a language Vorpal for the implementation of these methods is discussed
A system and language environment for scientific computing by Stanford University( Book )

2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide

We discuss the use of component adaptive methods for the solution of time dependent partial differential equations. After a brief discussion of the methods we identify several deficiencies of commonly used languages of scientific computing and introduce a graphical editor, VOUS, and a language, Vorpal, to solve these problems. We also discuss the interaction of the various components of our system and their interfaces
A visual object-oriented unification system by R Pichumani( Book )

2 editions published in 1989 in English and held by 2 WorldCat member libraries worldwide

This report introduces a software design platform which departs from the style of most design tools by acting as an extension to, rather than a replacement for, existing design tools. The ultimate goal of this system is to unify and integrate the various functions provided by text editors, graphics editors, text formatters, hyper-text and structured decomposition tools. It uses a very general data structure which can manifest itself in a variety of visual forms while enabling the user to easily create abd manipulate the objects it represents. This tool is useful for creating large, general purpose, hierarchically structured programs, data structures, documents, and other similar objects. Moreover, this system is designed to allow for a wide variety of functions to be performed on these data objects (such as graph traversal or functional mapping), both from within the environment as well as externally (for example, mapping concurrent computations onto parallel architectures using a post-processor). This system is also considered to be a springboard for investigating future directions in software design and information management
Numerical Methods Based on Additive Splittings for Hyperbolic Partial Differential Equations( Book )

1 edition published in 1981 in English and held by 2 WorldCat member libraries worldwide

We derive and analyze several methods for systems of hyperbolic equations with wide ranges of signal speeds. These techniques are also useful for problems whose coefficients have large mean values about which they oscillate with small amplitude. Our methods are based on additive splittings of the operators into components that can be approximated independently on the different time scales, some of which are sometimes treated exactly. The efficiency of the splitting methods is seen to depend on the error incurred in splitting the exact solution operator. This is analyzed and a technique is discussed for reducing this error through a simple change of variables. A procedure for generating the appropriate boundary data for the intermediate solutions is also presented. (Author)
3D composite grids for flow computations: the grid generation by Stanford University( Book )

2 editions published in 1991 in English and held by 1 WorldCat member library worldwide

Flow situations involving localized phenomena and 3D, complex geometries are very important and are often encountered in engineering applications in the aerospace, chemical and petroleum industries. Such geometries defy attempts to lay a single grid over the entire domain, for numerical solution of the problem using finite-difference methods. In a Composite Grid method, the domain is decomposed into overlapping regions which communicate at their boundaries. Each of these is individually transformed to a discrete, orthogonal parallelepiped grid. The transformed flow equations are then solved on these grids, in conjunction with the other grids which communicate with them, by using any of the wide variety of solvers including adaptive, multigrid versions. In this paper, we will describe the grid generation procedure, the data structure used to create the composite grid and some communication and other design issues
