Abstract

In this paper we propose a series of numerical and geometrical techniques that make possible to model geological processes with large deformation and complex geometry within sedimentary basin and lithosphere. These techniques facilitate the process of automatic meshing and remeshing of the geological model necessary for the solution of the differential equations governing geological processes. In addition, we show an efficient representation of geological structures that allows its decomposition and makes it optimized for parallel computing.
