Strand7 provides tools to model offshore floating structures such as boats subject to buoyant forces, payload and other loadings.
Buoyancy effects on a partially or fully submerged object can be considered in a nonlinear transient analysis by implementing a Factor vs Position table.
This table factors the applied pressure according to the relationship between hydrostatic pressure and the submerged depth, hence simulating the effects of buoyancy.
Another method to model buoyancy is by direct application of Archimedes’ principle, which is to apply the buoyancy forces in the negative gravity direction based on the submerged volume of an object.
Note that still water is modelled in this example, but the fluid dynamics of flow around the object are not considered.
