We consider the stability of finite-difference approximations to hyperbolic initial-boundary-value problems (IBVPs) in one spatial dimension. A complication is the fact that generally more boundary conditions are required for the discrete problem than are specified for the partial differential : Robert F.

Warming, Richard M. Beam. Abstract. A stability theory is developed for general difference approximations to mixed initial boundary value problems. The results are applied to certain commonly used difference approximations which are stable for the Cauchy problem, and different ways of defining boundary conditions are analyzed.

Ascher, Robert M. Mattheij, Robert D. Russell. I am wondering if someone have experience about the numerical stability of boundary conditions.

I have a finite element problem (non-linear) in elasticity solving with Newton-raphson algorithm and the solution using Dirichlet (displacement) boundary conditions is more stable (more steps can be reached) when compared to Neumann boundary conditions (forces). where and.

In the mathematical literature, a number of works have appeared on nonlocal boundary value problems, and one of the first of these was [].Il'in and Moiseev initiated the research of multipoint boundary value problems for second-order linear ordinary differential equations, see [2, 3], motivated by the study [4–6] of Bitsadze and by: 1.

Flows at high Reynolds numbers or heat transfer phenomena at large Peclet numbers, i.e. convection- dominated flows, are also examples of two-point boundary value problems which characterized by the presence of thin, viscous or heat-conducting layers where steep flow gradients occur, i.e.

'The strength of this book lies in its emphasis on a complete presentation of the underlying theories followed by clear steps and concise formulation applied to a plethora of problems, which include basic numerical schemes such as Euler and Runge-Kutta methods and relatively advanced schemes such as the pseudo-spectral method, spectral methods with body fitted grids, and the immersed boundary Cited by: 5.

From numerical relativity to supercomputing 20 Stability regions are a standard tool in the analysis of numerical formulas for ODE initial-value problems. Given a formula -- 2nd-order Adams-Bashforth, say, or 3rd-order backward differentiation -- the stability region is the region of the complex $\lambda \Delta t$-plane where the associated scalar constant-coefficient recurrence relation is stable.

D-stability from a numerical point of view R. Pavani ⁄ 1 Introduction A matrix A is called (positive) D-stable if DA is positive stable, i.e. all eigenvalues have strictly positive real parts, for all positive diagonal matrices D: The concept of D-stability of a matrix was ﬁrst introduced in mathematical economics [1].

Boundary Value Problems of Mathematical Physics / Edition 1. this graduate-level introduction is devoted to the mathematics needed for the modern approach to boundary value problems using Green's functions and using eigenvalue expansions. Now a part of SIAM's Classics series, these volumes contain a large number of concrete, interesting Price: \$ Most of these papers are focused on obtaining comparison theorems for different problems and different boundary conditions, whereas some of them deal with the existence of solutions for specific boundary value problems.

This is the case, for instance, of [21, 31, 35, 37, 38] by: 2. The goal of this article is to review some of the theory necessary to understand the continuum and discrete initial boundary-value problems arising from hyperbolic partial differential equations and to discuss its applications to numerical relativity; in particular, we present well-posed initial and initial-boundary value formulations of Cited by: ON THE RESOLVENT CONDITION KREISS MATRIX THEOREM REMARK.

Alexeyeva. Finally, it is easy to make mistakes when determining the extent of the imaginary stability interval for high-order Runge-Kutta methods. That is because the boundary of the stability region for such methods lies extremely close to the imaginary axis.

Therefore, roundoff errors can lead to incorrect conclusions; only exact calculations should be. The existence of unbounded nonnegative solutions of a boundary value problem for n th-order differential equations defined on an infinite interval is obtained by means of the Mönch fixed-point theorem.
