A Petrov-Galerkin finite element scheme for Burgers’ equation. (English) Zbl 0908.65089

Summary: Burgers’ equation is solved by a Petrov-Galerkin method using quadratic B-spline spatial finite elements. A linear recurrence relationship for the numerical solution of the resulting system of ordinary differential equations is obtained via a Crank-Nicolson approach involving a product approximation. Standard problems are solved to assess the properties of the algorithm.
