Book excerpt: Split numerical methods have been commonly used in computational physics for many years due to their speed, simplicity, and the accessibility of shock capturing methods in one-dimension. For a variety of reasons, it has been challenging to determine just how accurate operator split methods are, especially in the presence of curved wave features. One of these difficulties has been the lack of multidimensional shock capturing methods. Another is the difficulty of mathematical analysis of dis-continuous flow phenomena. Also, computational studies have been limited due to a lack of multidimensional model problems with analytic solutions that probe the nonlinear features of the flow equations. However, a new genuinely unsplit numerical method has been invented. With the advent of the Space-Time Conservation Element/Solution Element (CE/SE) method, it has become possible to attain high accuracy in multidimensional flows, even in the presence of curved shocks. Examples presented here provide some new evidence of the errors committed in the use of operator split techniques, even those employing unsplit corrections. In these problems, the CE/SE method is able to maintain the original cylindrical symmetry of the problem and track the main features of the flow, while the operator split methods fail to maintain symmetry and position the shocks incorrectly, particularly near the focal point of the incomi.

Book excerpt: Dimensionally split numerical methods have been in common use in computational physics for many years. This is due to the need for speed, the formal convergence of Strang splittings, and the accessibility of shock capturing techniques in one dimension. However, the lack of genuinely unsplit multidimensional shock capturing methods has made it difficult to access just how large the errors are in a dimensionally split approach. This applies in spite of splitting corrections that have been used to obtain formally "unsplit" methods. A new class of methods that are genuinely unsplit have recently been developed. These are the so-called "Conservation Element and Solution Element" (CE/SE) methods. Using these high accuracy methods, we show that converging flows and the subsequent expanding flows are accurately captured by CE/SE methods. Contrariwise, it will be shown that dimensionally-split Godunov and unsplit wave propagation methods distort the flow for the same cases, sometimes seriously.

This book was released on 2018-07-23 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attempt is made to give a unified and generalized formulation of a class of high resolution, explicit and implicit shock capturing methods, and to illustrate their versatility in various steady and unsteady complex shock wave computations. Included is a systematic review of the basic design principle of the various related numerical methods. Special emphasis is on the construction of the basis nonlinear, spatially second and third order schemes for nonlinear scalar hyperbolic conservation laws and the methods of extending these nonlinear scalar schemes to nonlinear systems via the approximate Riemann solvers and the flux vector splitting approaches. Generalization of these methods to efficiently include equilibrium real gases and large systems of nonequilibrium flows are discussed. Some issues concerning the applicability of these methods that were designed for homogeneous hyperbolic conservation laws to problems containing stiff source terms and shock waves are also included. The performance of some of these schemes is illustrated by numerical examples for 1-, 2- and 3-dimensional gas dynamics problems. Yee, H. C.
