Abstract

A novel time-stepping approach is presented for the three-dimensional thin-layer Navier-Stokes equations. The method involves a two factor approximate factorisation and uses a preconditioned conjugate gradient solution for one of the factors. The method has potential to provide most of the advantages of a fully unfactored method without the huge memory requirements. A partially implicit method is also considered. Results and a stability analysis are presented to evaluate the approaches.
