Detailed Description

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.

True indicates global coordinate system, and false local coordinate system.

◆ getApForValid()

virtual bool sel::ISELNode::getApForValid ( bool bForce ) const

pure virtual

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

◆ getFix()

virtual IVect sel::ISELNode::getFix ( bool tran_comp ) const
