RAMMS::Rockfall

RAMMS::Rockfall  applies a novel contact-algorithm to model rockfalls, as opposed to most other rockfall simulation programs relying solely on restitution coefficients. The model accounts for real rock shapes, computing their runout trajectory over 3D terrain, including their jump heights, velocity, rotational velocity, rotational and total kinetic energy. All possible modes of rockfall motion (jumping, rolling and sliding) are deterministically simulated. Dynamics of single trajectories can be individually inspected or sets of multiple trajectories can be statistically analyzed.
