Building {3D} vectorial links on unstructured volumic meshes

Abstract

3D modelisation of volumes with unstructured meshes, like tetrahedral meshes, needs a way to store knowledge about continuity of geological properties like porosity or permeability through fault, with respect to the throw vector. In 2D triangulated surfaces, this is done with so-called vectorial links which are manually created by the user. This approach cannot be extended in 3D, because of the added complexity, and thus only an automatic method may allow to create a consistent set of vectorial links in 3D. This article presents such a method, based on a simplified topological model for tetraedrized solids. Iso-value surfaces of a geological time property are computed, and surfacic vectorial links may be automatically set on these surfaces, and propagated in the volume.
