Creates an Opening Entity in a Polylinelist Hull, the opening is rectangular in shape. Used in conjuntion with the Proteus simulation.
|Hull Polylist/Any Surface||The Hull Entity that the opening is in|
|Top number/polyline||Optional, The upper boundary of the opening|
|Bottom number/polyline||Optional, The lower boundary of the opening|
|Length damagelength||The width (damagelength)|
|Location number||The X Location of the centre of the damage|
|Sections number||The number of sections that will define the opening|
|Reflect||Optional, Reflects the opening to the negative side of the hull|
|Connect Group1Name direction Group2Name||The groups that the opening can connect to, see below|
|Normal vector||The normal vector to align then opening normal to, see below.|
|CollapseHead PressureHead||The head required before the opening will allow flooding, default 0|
|OpeningTime Time||The time at which the opening will begin to allow flooding, default 0|
The opening can be connected to other entites using the connection definition in described above and functions in the flowing manner:
|A -> B||Group A is connected to Group B, nothing can flow from B to A.|
|A <- B||Group B is connected to Group A, nothing can flow from A to B.|
|A <-> B||Group A and Group B are connected together, flow is bi-directional.|
If SEA is specified as a group then the opening connect to the Sea in the Proteus Simulation.
Normals can be specified using axis direction, e.g.
|Z-||align to z negative direction|
|Y+||align to y positive direction|
or the Normal can be specified using user defined vector e.g.
[1, 1, 0]
Note: The Normal does not have to be unit length
