Energy and maximum norm estimates for nonlinear conservation laws by Pelle Olsson( Book )
3 editions published in 1994 in English and held by 76 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."

Stability and error estimation for component adaptive grid methods by Joseph Oliger( Book )
2 editions published in 1994 in English and held by 72 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)

Adaptive Grid Refinement for Numerical Weather Prediction by William C Skamarook( 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
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
Adaptive mesh refinement for hyperbolic partial differential equations by Marsha J Berger( Book )
1 edition published in 1983 in English and held by 2 WorldCat member libraries worldwide
The authors present an adaptive method based on the idea of multiple, component grids for the solution of hyperbolic partial differential equations using finite difference techniques. Based upon Richardson-type estimates of the truncation error, refined grids are created or existing ones removed to attain a given accuracy for a minimum amount of work. Their approach is recursive in that fine grids can themselves contain even finer grids. The grids with finer mesh width in space also have a smaller mesh width in time, making this a mesh refinement algorithm in time and space. This document includes algorithm, data structures and grid generation procedure, and concludes with numerical examples in one and two space dimensions. (Author)
Symbolic expressions of composite grid structures by Stanford University( Book )
2 editions published in 1991 in English and held by 2 WorldCat member libraries worldwide
In summary, graphs and s-expressions are really different manifestations of the same entities. While graphs are visual, they nonetheless possess dual representations in the textual s-expression alphabet. As a result, LISP, which is based entirely on s-expressions, is an ideal language for dealing with applications that perform extensive manipulations on graph-based objects. Scientific applications which make extensive use of both graph based objects as well as traditional numerical arrays can benefit by implementating their higher level data and control structures in LISP. Segments of code that are computationally intensive can be written in a static language such as C or FORTRAN and linked in with the higher level code. Such a design strategy could preserve the benefits of static compilation (i, e, . faster execution speed) while retaining the power and flexibility needed to manipulate complex data structures
3D Composite Grids for Flow Computations: the Grid Generation by Stanford University( Book )
2 editions published in 1991 in English and held by 2 WorldCat member libraries 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
3D Composite Grids Using Bezier Curves and Surfaces in Component Adaptive Methods by Stanford University( Book )
2 editions published in 1993 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 on complex geometries. After a brief exposition of the system and language requirements for an efficient use of these methods, we describe a grid generation procedure M*E*S*H, built upon Bezier constructs, coupled with a graphical editor VOUS to serve as a visualization platform, and a programming language Vorpal designed to facilitate their implementation. We also discuss the interaction of the various components of our system and their interfaces
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)
