“…Main dimensions and initial position of the floating block with an asymmetric mass distribution immersed in a viscous flow.Source:(Amaro Jr et al, 2019).Time history curves of horizontal (x), vertical (y) and rotational (Theta) motions at the center of mass of the rigid block are shown inFigure 4.5(a)-(c), respectively. The results of present MPS are compared with the results by using the finer resolution ( / 0 = 100) of Riemman-SPH(Vila, 1999), -SPH(Antuono et al, 2010), explicit incompressible smoothed particle…”
