i :=
Get the structural node ID number. This is defined as the ID number of the first element connected to the node and is not to be confused with the component-ID number.


Unlike other objects in FLAC3D, ID numbers for structural objects (elements, links, and nodes) refer to collections of elements and associated objects created together and representing a single overall structure. For structural objects, the unique, internally assigned ID number associated with the object is called the component-ID number. See the function.

Returns:i - structure node ID number
Arguments:sn - structure node pointer
