Scenario data

settled_bed.json preserves the 414 two-dimensional particle positions (pos) and corresponding radii (rad) from the former hard-coded RL bed module. Load it with Python’s json module when building an example; the library does not load it automatically. This is a saved scenario, not a general packing generator or a benchmark reference.

rotating_drum.stl is a small example boundary mesh: a 16-sided cylinder of radius 3 and depth 1.4, with two end caps and three radial lifters. Its 70 triangles describe a contact shell, including internal baffles, rather than a filled solid. Coordinates use the same reduced length units as the rotating-drum example.

Download the drum STL alongside the Python example, keeping it in a data subdirectory, or select another mesh with the JAXDEM_DRUM_STL environment variable described by that example.

soft_mode_packing.json is a prepared sixteen-disk configuration at shear strain 0.046. The soft-mode example relaxes this input again, then computes the spectrum and rearrangement during its run. The file records preparation parameters; it contains no cached analysis results.

Download the prepared packing into the same data subdirectory when running that example outside the repository.
