Poisson's equation, hexagonal grids and FFT methods: Periodic boundary conditions

A demonstration is undertaken of how the techniques developed by Pickering (1986) can be extended to deal with cases in which the boundary conditions are periodic in the j direction, as well as where the boundary conditions are periodic in both the i and the j directions. Numerical illustrations are...

Description
Summary:A demonstration is undertaken of how the techniques developed by Pickering (1986) can be extended to deal with cases in which the boundary conditions are periodic in the j direction, as well as where the boundary conditions are periodic in both the i and the j directions. Numerical illustrations are presented for both types of boundary condition. (O.C.)
