What is the best way to add a superstructure to a hull model to
calculate buoyancy and the effect of flooding ?
If you want to see the buoyancy contribution of the superstructure
in the STATUS reports, you should make it a separate part. The class
can be SUPER.
If you want the buoyancy of the superstructure to be combined with
the HULL, you should make it a component of the HULL part. For example,
In order to study the flooding of the superstructure,
you need to make "tanks" within it. For example,
ENDS 100, 150
To study the effect of partial flooding in ROOM1, you
will need to keep it as an INTACT tank and load it with some amount
of water. For example,
LOAD (ROOM1.C) = .1
If do not know the load fraction and want GHS to get it
for you from a water plane passing through a given point, set the
Reference Point at that point. For example,
REFPT= 120, -10, 20
LOAD HEIGHT: 0
This will set the load fraction such that the water surface
in ROOM1.C passes through the given point when the heel is 12 degrees
to starboard and the trim is zero.
