Split Points

The shell profile may be divided into a series of shell stiffener by a number of "split points" along the branch curve. The split point may be a principal plane or another object like a plane panel, a seam, a curve or another shell profile. The system will split the shell profile in these split points, one by one in the order they are given in input.

Important: The split points must be given in the order they appear along the trace of the shell profile. It does not matter of you arrange them in the same direction as the trace curve or in the reverse direction. However, there must be at least two split points otherwise AVEVA Marine cannot detect that the split points are given in reverse order. Consequently, if there are less than two split points, AVEVA Marine will assume that they are given in the direction of the trace curve.

The split points must be given in "End2" element in the "Connection" element of the shell stiffener. The split point in the first ShellStiffener element will be the split point between the first and the second stiffener. The split point in the second ShellStiffener element will be the split point between the second and the third stiffener,

The split point in End2 of the last Shell Stiffener element is special. This will not be interpreted as a split point, but as a limit for end 2 of the very last shell profile. In the same way you can set a limit for end 1 of the first shell stiffener by defining data in End1/Connection element of the first ShellStiffener element of the branch.

As a consequence, the number created of shell stiffener model objects is always equal to the number ShellStiffener elements given in the input file. This ShellProfile element will create a transversal with one single shell stiffener. The second end of the stiffener will end at the panel "JUMBO-PLF7000":

<ShellProfile ObjId="SPT900" SubType="Long">

...

<Branch>

<Trace>

<ByPrincipalPlane Z="7500"/>

</Trace>

<ShellStiffener>

<End2>

<Connection>

<Stored ObjType="PlanePanel" ObjId="JUMBO-PLF7000"/>

</Connection>

</End2>

</ShellStiffener>

</Branch>

</ShellProfile>

This ShellProfile element will create a transversal with two shell stiffeners, one on each side of the panel "JUMBO-PLF7000":

<ShellProfile ObjId="SPT900" SubType="Long">

...

<Branch>

<Trace>

<ByPrincipalPlane Z="7500"/>

</Trace>

<ShellStiffener>

<End2>

<Connection>

<Stored ObjType="PlanePanel" ObjId="JUMBO-PLF7000"/>

</Connection>

</End2>

</ShellStiffener>

<ShellStiffener>

</ShellStiffener>

</Branch>
