Do you mean hydrostatic forces that produce buoyancy? That is easily accomplished and many discussions have been posted about that.

There is a 'native' ACT extension inside WB mechanical now - there is an ACT extension that comes with 2021 R2 called AqwaLoadMapping (see below) - so you might be able to use it.
(this link shows the ACT extension manager which is accessed via Extensions>Manage Extensions, and the AqwaLoadMapping extension: https://www.padtinc.com/blog/tag/ansys-mechanical/).

perhaps can comment if this is suitable for your application and if there any limitations with the AqwaLoadMapping extension for this type of modelling?

many thanks

My colleague Yu has replied in the other thread that you've created for this question, but to back up her answer:
When you add a Hydrodynamic Diffraction system to the Project Schematic, the AqwaLoadMapping ACT extension is automatically loaded for you. To transfer hydrodynamic pressures to Static Structural you link the hydrodynamic Solution cell to the structural Setup cell. You will need to Update the Hydrodynamic Diffraction Solution cell from the Project Schematic (rather than just Solve inside the Aqwa Workbench editor). Once the hydrodynamic calculation is complete, open the Static Structural system, add a Hydrodynamic Pressure object, and select the wave frequency/direction/phase angle that you are interested in; you can also select all wave frequency/direction pairs, and/or a sequence of wave phase angles, to find a worst case. Right-click Generate on the Hydrodynamic Pressure object to view the hydrodynamic pressures mapped on to the structural model. In addition you can map time domain pressures in a similar way - check the Aqwa User Manual, as Yu suggested, for more information.
Cheers, Mike

Thank you and will have a go at this! Will revert back if I have any more questions/problems.
However, is there a manual or guide for aqwaloadmapping extension, for a finer breakdown of how to use it?

[Erik Kostson]

Think the Aqwa user manual manual inside Help (see link) is good and detailed: 8.1. The Hydrodynamic Pressure Mapping Extension (ansys.com) -
Also in the ansys learning hub (ALH) there are some course notes and some workshops also (ALH is a subscription/paid service with many many courses: https://www.ansys.com/services/ansys-learning-hub ).

Hope this helps

All the best

Erik
