Detailed Description

Class implementing node in finite element mesh.

Node possess degrees of freedom (see base class DofManager). Node is attribute of few elements and it is managed by domain. Node manages its position in space, and if specified local coordinate system in node. If local coordinate system is defined, all equilibrium equations are assembled in this system and therefore all DOFs and applied boundary and initial conditions apply in this local coordinate system. By default, global coordinate system is assumed in each node. For description, how to prescribe local coordinate system in node, see input file description section.

Tasks include:

Managing its position in space. In geometrically linear analysis, this only amounts to managing its coordinates.
Managing its local coordinate system. If it is defined, all equilibrium equations are assembled within it. This system is defined by triplet of unit vectors of local coordinates expressed in terms of global axes. This tripled is stored in localCoordinateSystem, its item ij is angle between e'(i) and e(j), where e' is local axis.
Managing its degrees of freedom (method giveDof) ;
Calculating its nodal load vector;
Printing and updating at end of step ;
Managing its swapping to and from disk.

contextIOResultType oofem::Node::restoreContext	(	DataStream &	stream,
		ContextMode	mode,
		void *	obj = `NULL`
	)

virtual

Restores the receiver state previously written in stream.

See also: saveContext

Parameters

stream	Input stream.
mode	Determines amount of info available in stream (state, definition, ...).
obj	Special parameter for sending extra information.

Returns: contextIOResultType.

Exceptions

throws an ContextIOERR exception if error encountered.

Todo:: Smart pointers would be nicer here

contextIOResultType oofem::Node::saveContext	(	DataStream &	stream,
		ContextMode	mode,
		void *	obj = `NULL`
	)

virtual

Stores receiver state to output stream.

Parameters

stream	Output stream.
mode	Determines amount of info required in stream (state, definition, ...).
obj	Special parameter, used only to send particular integration point to material class version of this method.

Returns: contextIOResultType.

Exceptions

throws an ContextIOERR exception if error encountered.

void oofem::Node::setCoordinates ( FloatArray coords )

inline

Sets node coordinates to given array.

Parameters

coords New coordinates for node.

void oofem::Node::updateYourself ( TimeStep * tStep )

virtual

Updates receiver at end of time step (i.e.

after equilibrium has been reached). If EngngModel formulation ( see giveFormulation() member function) returns actualized Lagrange mode, receiver updates its coordinates according to solution.

Parameters

tStep Time step for which to update.
