How to include water buoyancies effect in analysis for an abaqus model. The abaqus model is developed using shell and solid elements

 

Comments

I do not use ABAQUS, but I will suggest something anyway--isn't bouyancy a body force in the opposite direction of the gravity? If you can apply a gravity load to the body, you should be able to apply a bouyancy force in the opposite direction. Watch the units on your "density"--Some software might want mass density (Greek letter "rho") while others might want weight density (Greek letter "gamma").
