Bidisperse sphere packs generated under gravity

Description

Bidisperse sphere packs consisting of small (clay) and large (silt) grains were generated under the effect of gravity to model mudrocks and study the petrophysical properties. Multiple, periodic, dense, bidisperse sphere packs were created with large grain volume concentrations (VL) increasing from 0 to 100 %. This was done for large to small grain radius ratios of 2:1, 5:1, 7:1, and 10:1 with constant sphere pack length 10 units in x, y, z directions. The data for each sphere pack consists of the x, y, z coordinates of the sphere centers and the sphere radii stored in .csv files. Cross-sectional images visualized in ParaView are shown for clarity.
