Study of floating bodies in wave ny using smoothed particle hydrodynamics (SPH)

One of the problems is the environment area which involves the floating of body with effective microorganism (SM). As a result, we need a detail description as well as calculation of floating body is using finite difference method (FD). However, this method produces low accuracy results. Beside, FD...
