From: Triggering avalanches by transverse perturbations in a rotating drum
Snapshot of the rotating drum obtained with MercuryDPM. The imposed transverse forcing is along the \(x-\)direction, such that the movement of the walls is \(x(t) = A\sin (2\pi f t)\). In this case, \(\Omega = {1}\hbox { rpm}\) and \(A=0\).
