Interface to provide access to structural element nodes.
Each node is associated with six degrees of freedom, comprised of three translational components and three rotational components. Each node has its own orthogonal coordinate system. The node-local system provides the directions in which the equations of motion for the node are solved, and also defines the direction in which the node can be attached to a target entity via a link.

pure virtual |
Returns the added mass in node-local sytem.
If parameter tran_comp is true, returns translational comps., else rotational comps.
|
pure virtual |
Returns generalized angular velocity expressed in local-system coordinates if parameter
local_sys is true.

pure virtual |
Return coordinate system in which generalized forces are expressed.
True indicates global coordinate system, and false local coordinate system.

Returns true if applied forces are valid. If parameter bForce is true, then
queries the translational components, otherwise the rotational components.

or 0 for the last element of the list. See ISELNodeList::getFirstSELNd().
|
pure virtual |
Returns the node position, see setPos().
If parameter cur is set to true, returns the current position.
If parameter cur is set to false, returns the reference position.
The current position is updated after each time step. The reference position is the configuration for which the stiffness matrices have been formed and does not change during a small-strain analysis. During a large strain analysis, the reference point is set equal to current position during each large-strain update.
