## Abstract

Considers the fractional step method, and studies problems involving immersed boundaries in which the boundaries are modelled by a chain of Lagrangian particles connected by springs. Adapts the algorithm for the construction of Voronoi meshes for the case of a periodic domain, noting possible use of the Delauney triangulation. Proves that the discrete divergence and gradient operators are weakly consistent with the corresponding continuous operators. Describes a two level iteration for the solution of discrete Helmholtz equations and presents a vector field on to its divergence free part. Finally, obtains a fractional step method for the Navier-Stokes equations. (C.J.U.)
