The Permeabilities are set in a table in the Permeability dialog. Use the Add and Delete buttons to add or delete rows from the table. The permeabilities may be sorted by double clicking on the permeability column heading. The last set of permeabilities used will be recalled from the registry when Hydromax is started.

The Permeability dialog is used to specify the permeabilities to be used for the Floodable Length analysis; the permeability is applied over the entire length of the vessel.

This permeability is unrelated to compartment, tank or non-buoyant volume permeability and is only used for floodable length calculations.

The individual permeability of each compartment (or tank) is specified in the Compartment definition table. The compartment, tank and non-buoyant volume permeabilities are used when calculating the effects of damage, and/or calculating the weights of fluids in tanks in the loadcase.
