Discrete Element Model Simulations for a Granular Bed Undergoing Shear Deformation

Discrete Element Model (DEM) Archive for, "Shear Variation at the Ice-Till Interface Changes the Spatial Distribution of Till Porosity and Meltwater Drainage" by,<br> Indraneel Kasmalkar, Anders Damsgaard, Liran Goren, Jenny Suckale <br> This dataset contains the output files of the DEM simulations for understanding how the porosity of a granular bed evolves with an imposed laterally varying shear. The DEM simulations are performed using Sphere (https://src.adamsgaard.dk/sphere/), developed by Anders Damsgaard. The output files are in the 'output' folder.<br> The porosity values are curated and stored in 'porosities' folder as 4D numpy arrays.<br> The results are generated as .pdf files in the 'Images' folder.<br> The scripts are stored in the 'python' folder. <br> The main file in the 'python' folder is MyVisualization.py. To run the script you will need Python 3.6 or newer, with the following packages: numpy, scipy, matplotlib, colorbrewer, math, pickle In MyVisualization.py, go to line<br> if __name__ == '__main__' Before the line, you can change the variable plot_type to get the plot you need.<br> The options for plot_type are listed in a comment right before the variable.<br> You can limit the plotting to either simple shear ('unif') or laterally varying shear ('hl') within each if condition thereafter
