The nonconvex multi-dimensional Riemann problem for Hamilton-Jacobi equations by Stanley Osher( Book )

5 editions published in 1989 in English and held by 185 WorldCat member libraries worldwide

Simple inequalities are presented for the Riemann problem for a Hamilton Jacobi equation in N space dimension when neither the initial data nor the Hamiltonian need be convex (or concave). The initial data is globally continuous, affine in each orthant, with a possible jump in normal derivative across each coordinate plane, x sub i = 0. The inequalities become equalities whereever a maxmin equals a minmax and thus an exact closed form solution to this problem is then obtained. Keywords: Hamilton Jacobi equations; Riemann problem; Godunov scheme

Triangle based TVD schemes for hyperbolic conservation laws by Institute for Computer Applications in Science and Engineering( Book )

6 editions published in 1990 in English and held by 177 WorldCat member libraries worldwide

A triangle based TVD (total variation diminishing) scheme for the numerical approximation of hyperbolic conservation laws in two space dimensions is constructed. The novelty of the scheme lies in the nature of the preprocessing of the cell averaged data, which is accomplished via a nearest neighbor linear interpolation followed by a slope limiting procedure. Two such limiting procedures are suggested. The resulting method is considerably more simple than other triangle based non-oscillatory approximations which, like this scheme, approximate the flux to second order accuracy. Numerical results for linear advection and Burgers' equation are presented. Keywords: Hyperbolic conservation laws; Limiters; Triangular threads. (jhd)
High order essentially non-oscillatory schemes for Hamilton-Jacobi equations by Stanley Osher( Book )

5 editions published in 1990 in English and held by 163 WorldCat member libraries worldwide

Hamilton-Jacobi (H-J) equations are frequently encountered in applications, e.g. in control theory and differential games. H-J equations are closely related to hyperbolic conservation laws -- in one space dimension the former is simply the integrated version of the latter. Similarity also exists for the multi-dimensional case, and this is helpful in the design of difference approximations. In this paper we investigate high order essentially non-oscillatory (ENO) schemes for H-J equations, which yield uniform high order accuracy in smooth regions and resolve discontinuities in the derivatives sharply. The ENO scheme construction procedure is adapted from that for hyperbolic conservation laws. We numerically test the schemes on a variety of one-dimensional and two-dimensional problems, including a problem related to control optimization, and observe high order accuracy in smooth regions, good resolution of discontinuities in the derivatives, and convergence to viscosity solutions.

Efficient implementation of essentially non-oscillatory shock capturing schemes, II by Chi-Wang Shu( Book )

5 editions published between 1987 and 1988 in English and held by 160 WorldCat member libraries worldwide

In the computation of discontinuous solutions of hyperbolic conservation laws, TVD (total variation diminishing), TVB (total variation bounded) and the recently developed ENO (essentially non-oscillatory) schemes have proven to be very useful. In this paper two improvements are discussed: a simple TVD Runge-Kutta type time discretization, and an ENO construction procedure based on fluxes rather than on cell averages. These improvements simplify the schemes considerably--especially for multi dimensional problems or problems with forcing terms. Preliminary numerical results are also given. Keywords: Construction laws; Essentially non oscillatory; TVD; Runge Kutta method; Numerical analysis
Uniformly high-order accurate non-oscillatory schemes by Ami Harten( Book )

3 editions published in 1985 in English and held by 142 WorldCat member libraries worldwide

The authors begin the construction and the analysis of nonoscillatory shock capturing methods for the approximation of hyperbolic conservation laws. These schemes share many desirable properties with total variation diminishing schemes, but TVD schemes have at most first order accuracy, in the sense of truncation error, at extrema of the solution. This paper constructs a uniformly second order approximation, which is nonoscillatory in the sense that the number of extrema of the discrete solution is not increasing in time. This is achieved via a nonoscillatory piecewise linear reconstruction of the solution form its cell averages, time evolution through an approximate solution of the resulting initial value problem, and averaging of this approximate solution over each cell. Additional Keywords: Computations; Charts; operators(mathematics). (Author)

Fast wavelet based algorithms for linear evolution equations by Björn Engquist( Book )

6 editions published in 1992 in English and held by 81 WorldCat member libraries worldwide

We devise a class of fast wavelet based algorithms for linear evolution equations whose coefficients are time independent. The method draws on the work of Beylkin, Coifman, and Rokhlin 1 which they applied to general Calderon-Zygmund type integral operators. We apply a modification of their idea to linear hyperbolic and parabolic equations, with spatially varying coefficients. A significant speedup over standard methods is obtained when applied to hyperbolic equations in one space dimension and parabolic equations in multidimensions. wavelets; hyperbolic; parabolic; numerical methods
High order filtering methods for approximating hyperbolic systems of conservation laws by Frédéric Lafon( Book )

4 editions published in 1990 in English and held by 81 WorldCat member libraries worldwide

In the computation of discontinuous solutions of hyperbolic systems of conservation laws, the recently developed ENO (Essentially Non-Oscillatory) schemes appear to be very useful. However, they are computationally costly compared to simple central difference methods. In this paper we develop a filtering method which uses simple central differencing of arbitrarily high order accuracy, except when a novel local test indicates the development of spurious oscillations. At these points, generally few in number, we use the full ENO apparatus, maintaining the high order of accuracy, but removing spurious oscillations. Numerical results indicate the success of the method. We obtain high order of accuracy in regions of smooth flow without spurious oscillations for a wide range of problems and a significant speed up of generally a factor of almost three over the full ENO method. Keywords: Charts; Burger equation; Contract discontinuity. (kr)
Essentially nonoscillatory postprocessing filtering methods by Frédéric Lafon( Book )

7 editions published between 1991 and 1992 in English and held by 81 WorldCat member libraries worldwide

High order accurate centered flux approximations used in the computation of numerical solutions to nonlinear partial differential equations produce large oscillations in regions of sharp transitions. In this paper, we present a new class of filtering methods denoted by ENO-LS (Essentially Nonoscillatory Least Squares) which constructs an upgraded filtered solution that is close to the physically correct weak solution of the original evolution equation. Our method relies on the evaluation of a least squares polynomial approximation to oscillatory data using a set of points which is determined via the ENO framework. Numerical results are given in one and two space dimensions for both scalar and systems of hyperbolic conservation laws. Computational running time, efficiency and robustness of the method are illustrated in various examples such as Riemann initial data for both Burgers' and Euler's equations of gas dynamics. In all standard cases the filtered solution appears to converge numerically to the correct solution of the original problem. Some interesting results based on nonstandard central difference schemes, which exactly preserve entropy, and have been recently shown generally not to be weakly convergent to a solution of the conservation law, are also obtained using out filters.

Solution of the hydrodynamic device model using high-order non-oscillatory shock capturing algorithms by Institute for Computer Applications in Science and Engineering( Book )

5 editions published in 1989 in English and held by 75 WorldCat member libraries worldwide

A micron N+ - N - N+ silicon diode is simulated via the hydrodynamic model for carrier transport. The numerical algorithms employed are for the non-steady case, and a limiting process is used to reach steady state. The novelty of our simulation lies in the shock capturing algorithms employed, and indeed shocks, or very rapid transition regimes, are observed in the transient case for the coupled system, consisting of the potential equation and the conservation equations describing charge, momentum, and energy transfer for the electron carriers. These algorithms, termed essentially non-oscillatory, have been successfully applied in other contests to models the flow in gas dynamics, magnetohydrodynamics and other physical situations involving the conservation laws of fluid mechanics. The method here is first order in time, but the use of small time steps allows for good accuracy. Runge Kutta methods allow one to achieve higher accuracy in time of desired. The spatial accuracy is of high order in regions of smoothness. (JHD)
