Discrete Element Model Simulations for a Granular Bed Undergoing Shear Deformation

<p>Discrete Element Model (DEM) Archive for,</p> <p>&quot;Shear Variation at the Ice-Till Interface Changes the Spatial Distribution of Till Porosity and Meltwater Drainage&quot;</p> <p>by,<br> Indraneel Kasmalkar, Anders Damsgaard, Liran Goren, Jenny Suckale</p> <p><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 (<a href="https://src.adamsgaard.dk/sphere/">https://src.adamsgaard.dk/sphere/</a>), developed by Anders Damsgaard.</p> <p>The output files are in the &#39;output&#39; folder.<br> The porosity values are curated and stored in &#39;porosities&#39; folder as 4D numpy arrays.<br> The results are generated as .pdf files in the &#39;Images&#39; folder.<br> The scripts are stored in the &#39;python&#39; folder.</p> <p><br> The main file in the &#39;python&#39; folder is MyVisualization.py.</p> <p>To run the script you will need Python 3.6 or newer, with the following packages:</p> <p>numpy, scipy, matplotlib, colorbrewer, math, pickle</p> <p>In MyVisualization.py, go to line<br> if __name__ == &#39;__main__&#39;</p> <p>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 (&#39;unif&#39;) or laterally varying shear (&#39;hl&#39;) within each if condition thereafter</p>
