The Hydrodynamic Pressure Add-on allows you to transfer external surface and internal tank pressures, selected loads and structural accelerations calculated in a Hydrodynamic Diffraction or time domain Hydrodynamic Response analysis onto panel and beam elements in a Static Structural analysis. This removes the need to create, manipulate and run hydrodynamic load files external to Workbench. For more information about this Add-on, see The Hydrodynamic Pressure Add-on.
