The boundary conditions are defined as described in Figure.3.13. At the inlet the flow, velocity is imposed and hydrostatic.Pressure is imposed at the outlet. The following.Current velocities are used in the different computations.U0 = 5 cm / s 7.5, cm / s 10, cm / s and 15 cm / S (see also section.3.3.2.1).Both the far field and water surface are considered as.Slip walls. A no-slip condition is set at the submerged.Buoyant body and skirt surface in order to impose zero.Velocity at the wall.Computat ional modeling: Mesh.For computational modeling the computational, domain.Is divided into elements of simple geometry also called,,Mesh. The meshing strategy aims at capturing the evolution.Of the quantities resolved by the, algorithm (velocityPressure). This is done within each cell for each, timestep.Of the simulation. Smaller cells allow, for smallerMore, detailed changes and higher accuracy. A sufficient.Small change across, a cell i.e. Small cell size is required,,For the algorithm to give a correct result.
