Abstract

This paper investigates the possibility to produce dense sphere packings from geomodels so that geomechanical analyses can be performed later on through discrete element modeling. We present here how the SpherePadder algorithm, which can generate dense sphere packings from tetrahedral meshes, has been adapted and enhanced for geological modeling. The method is currently able to produce sphere packings for homogeneous medium (i.e. one constitutive material) containing fractures. In addition, we have worked towards assigning an attribute to each spheres corresponding to volumetric region. Early results are promising but further work is needed to address multi- material domains in SpherePadder.
