Migration of a floating rigid circular disk to the center line of a channel: vertical position \(r_{y}\) and horizontal velocity \(u_{x}\) of the center of the floating circular disk in the channel computed with the proposed formulation and an initial particle spacing of \(\Delta {}x = 2.0 \times 10^{-4}\) (red dashed line) and \(\Delta {}x = 1.0 \times 10^{-4}\) (black solid line) compared to the reference solution [8] (crosses)
