class(node),	intent(in)			::	nd1	The first node of the element.
class(node),	intent(in)			::	nd2	The second node of the element.
real(kind=real64),	intent(in),	optional,	dimension(:)	::	direction	An optional 3-element vector defining the spring axis. The vector must be non-zero and is normalized internally. If not supplied, the axis is defined by the vector from node 1 to node 2, in which case the nodes must not be coincident.
