Finite difference methods for advection and diffusion

Trojan, Alice von. January 2001 (has links) (PDF)
Includes bibliographical references (leaves 158-163). Concerns the development of high-order finite-difference methods on a uniform rectangular grid for advection and diffuse problems with smooth variable coefficients. This technique has been successfully applied to variable-coefficient advection and diffusion problems. Demonstrates that the new schemes may readily be incorporated into multi-dimensional problems by using locally one-dimensional techniques, or that they may be used in process splitting algorithms to solve complicatef time-dependent partial differential equations.

An error analysis of the numerical method of lines.

Bidie, Judith Nomantande Maureen. January 2011 (has links)
M. Tech. Mathematical Technology / Makes use of a linear PDE with a known analytical solution and solve it using the NDSolve built in Mathematica function. NMOL will be used directly on the same problem and then Joubert, Greeff and Fays error analysis will be implemented. The results obtained from this error analysis technique will be compared with the known conventional approach which uses the analytical solution. In this way, appropriate conclusions can be drawn about the accuracy of NMOL.
