Paper Abstract

In this paper we study point location of a regular 3D hexahedral grid. This is useful for applications that modelize wave propagation in a spatial 3D subdivision by the finite difference method. The current numerical solvers, like those employed in seismic wave propagation, can treat a billion points. It is thus necessary to resort to powerful localization methods in time. We propose a new particularly fast method based on results of discrete geometry. The principle of this method is based on a discretization of the faces of this 3D subdivision.
