We introduce the first extension of a Lattice Gas Automaton (LGA) model to
accurately replicate observed emergent phenomena in granular materials with a
special focus on previously unexplored jamming transitions by incorporating
gravitational effects, energy dissipation in particle collisions, and wall
friction. We successfully reproduce flow rate evolution, density wave
formation, and jamming transition observed in experiments. We also explore the
critical density at which jamming becomes probable. This research advances our
understanding of granular dynamics and offers insights into the jamming
behavior of granular materials
