Özet

In this paper, for the numerical solution of Burgers' equation, we give two B-spline finite element algorithms which involve a collocation method with cubic B-splines and a Galerkin method with quadratic B-splines. In time discretization of the equation, Taylor series expansion is used. In order to verify the stabilities of the purposed methods, von-Neumann stability analysis is employed. To see the accuracy of the methods, L-2 and L-infinity error norms are calculated and obtained results are compared with some earlier studies. (C) 2010 Elsevier B.V. All rights reserved.
