چکیده
In this paper, we resolve the ever-present confusion over QUICK scheme: it is a second-order scheme or third-order scheme. The scheme, as proposed in original reference [B. P. Leonard, Comput. Methods. Appl. Mech. Eng., 19, (1979), 59-98], (not second-order) finite-volume for integral form of general nonlinear conservation law with point-valued solutions stored at cell centers numerical solutions. Third-order accuracy proved by careful and detailed truncation error analysis demonstrated series thorough tests. requires spatial discretization time derivative to preserve unsteady problems. Two techniques are discussed, including QUICKEST Leonard. Discussions given on how mistakenly found be accurate. This paper intended serve clarify any about also basis clarifying unstructured-grid schemes will discuss subsequent paper.

A numerical scheme for space-time fractional advection-dispersion equation
In this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. We utilize spectral-collocation method combining with a product integration technique in order to discretize the terms involving spatial fractional order derivatives that leads to a simple evaluation of the related terms. By using Bernstein polynomial basis, the problem is transformed in...
متن کاملA numerical scheme for solving nonlinear backward parabolic problems
In this paper a nonlinear backward parabolic problem in one dimensional space is considered. Using a suitable iterative algorithm, the problem is converted to a linear backward parabolic problem. For the corresponding problem, the backward finite differences method with suitable grid size is applied. It is shown that if the coefficients satisfy some special conditions, th...
متن کاملA numerical scheme
Many moving boundary problems that are driven in some way by the curvature of the free boundary are gradient flows for the area of the moving interface. Examples are the Mullins-Sekerka flow, the Hele-Shaw flow, flow by mean curvature, and flow by averaged mean curvature. The gradient flow structure suggests an implicit finite differences approach to compute numerical solutions. The proposed nu...
متن کاملA Parameter Uniform Numerical Scheme for Singularly Perturbed Differential-difference Equations with Mixed Shifts
In this paper, we consider a second-order singularly perturbed differential-difference equations with mixed delay and advance parameters. At first, we approximate the model problem by an upwind finite difference scheme on a Shishkin mesh. We know that the upwind scheme is stable and its solution is oscillation free, but it gives lower order of accuracy. So, to increase the convergence, we propo...
متن کاملA Numerical Scheme for Bsdes
In this paper we propose a numerical scheme for a class of backward stochastic differential equations (BSDEs) with possible path-dependent terminal values. We prove that our scheme converges in the strong L2 sense and derive its rate of convergence. As an intermediate step we prove an L2-type regularity of the solution to such BSDEs. Such a notion of regularity, which can be thought of as the m...
