We propose a workflow for updating 3D geological meshed models to test different layering scenarios and to assess their impact on the simulation of CO2 injection. This workflow operates on a tetrahedral mesh that encodes rock unit information as well

Testing scenarios on geological models: local interface insertion in a 2D mesh and its impact on seismic save simulation

Autor: Capucine Legentil, Paul Cupillard, Guillaume Caumon, Jeanne Pellerin

In this work, we consider a relatively simple case of fluid monitoring in a subsurface gas reservoir. Seismic wave velocities for porous rocks vary depending on fluid saturation, and our objective is to quantitatively evaluate the impact of the water

Indirect hex-dominant meshing methods rely on the detection of adjacent tetrahedra that may be combined to form hexahedra. In this paper we introduce an algorithm that performs this identification and builds the set H of all possible combinations of

International audience; Incorporating prior geological knowledge in geophysical process models often meetspractical meshing challenges and raises the question of how much detail is to be includedin the geometric model. We introduce a strategy to auto

A 44-element mesh of Schneiders' pyramid: bounding the difficulty of hex-meshing problems

Autor: Kilian Verhetsel, Jeanne Pellerin, Jean-François Remacle

Publikováno v: CAD Computer Aided Design, Vol. 116 (2019) (2019)

This paper shows that constraint programming techniques can successfully be used to solve challenging hex-meshing problems. Schneiders’ pyramid is a square-based pyramid whose facets are subdivided into three or four quadrangles by adding vertices
