Topological Considerations

The topology of a room may be of any complexity. The system will, however, have certain restrictions on how complicated the geometry of a room may be.

Basically, a room must be of a box‑like shape, that means, in principle have six walls. It is further supposed to make sense to talk about a restriction in the aft, forward, port side, starboard side direction as well as in the direction up and down. However, the limits need not be parallel to a principal plane.

On the other hand, a "prismatic" room (for example, a side tank) in the forward part of the ship may well have the shell as the limit towards PS and in the forward and the downwards directions.

The user is supposed to partition rooms with a complicated topology into sub-rooms.

It is further supposed that all panels within a defined room shall be calculated (except those explicitly excluded), that means, it is not possible to define a room within another room to be excepted from the calculations.

Note: Be aware that it is the possible within the input to subtract the area of some surfaces/rooms from the sum of others!
