Introduction

A novel Discrete Element Method (DEM) employing polyhedral elements based on experimental set-up parameters is developed. It is implemented in an algorithm that simulates a dynamic model of creep deformation based on observed snow grains packing. The model uses a grain-scale algorithm that requires geometrical input parameters from a three-dimensional (3D) scans of the observed snow grains packing. The 3D high resolution image was obtained from scanning a cylindrical snow specimen using Synchrotron X-ray Diffraction Contrast Tomography (DCT) technique. Xrays.jpg

In the mean time the DEM algorithm is implemented YADE in the older version of yade.
