1. A computer implemented method for conducting a simulation of physical properties of a porous medium, comprises:
receiving by a computer, a micro-CT 3D image that captures a representative elemental volume of the porous medium, the porous medium defined as having mineral types and fluid types with individual grains and grain to grain contacts;
labeling by the computer the micro-CT 3D image as individual voxels according to mineral and fluid types;
labeling by the computer the mineral type voxels as belonging to separated and fixed individual grains;
transforming by the computer the labeled voxels into an unstructured conformal mesh representation for all grains; and
applying the unstructured conformal mesh representation to a parametric cohesive contact engine, with the parametric cohesive contact engine executing a parametric cohesive contact model that has an adjustable parameter, a critical separation δ0 that is conditioned according to a consolidation level,
wherein the critical separation δ0 is a length.
