The Offshore Add-on exposes the OCEAN commands in Mechanical APDL, which can be used to include the hydrodynamic loads on submerged beam and pipe elements – resulting from the motion of the structure through the fluid, or from the fluid motion around the structure due to current or waves – in Static Structural, Transient Structural, Modal and Harmonic Response analyses. For more information about this Add-on, see The Offshore Add-on.
