RAHIMPOUR, Majid  e  TAVAKOLI, Ali. Multi-grid Beam and Warming scheme for the simulation of unsteady flow in an open channel. Water SA [online]. 2011, vol.37, n.2, pp.229-235. ISSN 1816-7950.

In this paper, a multi-grid algorithm is applied to a large-scale block matrix that is produced from a Beam and Warming scheme. The Beam and Warming scheme is used in the simulation of unsteady flow in an open channel. The Gauss-Seidel block-wise iteration method is used for a smoothing process with a few iterations. It is also shown that the governing equations determine the type of prolongation and restriction operators for the multi-grid algorithm.

Palavras-chave : Multi-grid algorithm; Beam and Warming scheme; open channel flow.
