The boundary conditions are defined as described in Figure3.13. At the inlet, the flow velocity is imposed and hydrostaticPressure is imposed at the outlet. The followingCurrent velocities are used in the different computationsU0 cm = 5 / 7.5 / s, cm s, 10 cm / s and 15 cm / S (see also section3.3.2.1)Both the far field and water surface are considered asSlip walls. A no-slip condition is set at the submergedBuoyant body and skirt surface in order to impose zeroVelocity at the wall.Computat ional modeling: MeshFor computational modeling, the computational domainIs divided into elements of simple geometry, also calledMesh. The meshing strategy aims at capturing the evolutionOf the quantities resolved by the algorithm (velocityPressure). This is done within each cell, for each timestepOf the simulation. Smaller cells allow for smallerMore detailed changes, and higher accuracy. A sufficientSmall change across a cell, i.e. Small cell size, is requiredFor the algorithm to give a correct result.
