Slender Element

Long, slender elements can be used to model jacket legs and bracings or spool pieces.
A slender object such as a spool piece will normally have a 3-D geometry consisting of a number of straight elements with different orientation, and can be modeled by a set of slender elements.
End connectors can be modeled either by a short element or by a concentrated, fixed element. Small-body theory is used to calculate forces both for the slender element and the concentrated fixed element.
Stiff connection implies that all the sub-body (slender element or fixed, concentrated element) forces are calculated and transferred to the main body.
Each slender element specified by the user is divided into strips with equal length.
