Snapshots of the vibrating beam: The pressure field at different time steps using mesh size Δx = L0/2 and time step size Δt = 10−3T0. The deformation states at the corresponding time steps using mesh size Δx = L0/12 and time step size Δt = 10−4T0 are shown as the black grid. The light blue grid shows the mesh with size Δx = L0/2 at time t = 0.
