Cratering by the oblique impact of a spinning projectile

These files provide a complete example of the setup and workflow required to perform and analyze a numerical simulation of an oblique impact of a spinning projectile onto a granular bed. The simulation is conducted using the open-source Discrete Element Method (DEM) software LIGGGHTS.

The methodology has been thoroughly tested, and the obtained numerical results show good agreement with experimental data reported in the literature, confirming the reliability of the setup.

The dataset includes:

An initialization example, illustrating all necessary steps for preparing the granular bed and positioning the projectile; and

A main simulation case, which reproduces the actual impact event.

Additionally, an Octave post-processing code is provided to facilitate the analysis of the simulation outputs. This code allows users to extract, process, and visualize quantities such as position, velocity, acceleration, and forces acting on the projectile during impact.
