Detailed Description

Point object used to represent finite element nodes.

Point object used to represent finite element nodes, data points etc. Important notes: An unlimited number of fields may be defined at nodes to store parameters, derivatives, host mesh locations, strings etc. Coordinates are just another field: there can be zero or more coordinate fields defined on a node. Also, since Zinc elements are not iso-parametric, it is not sufficient to define field parameters at a node in the same manner as an existing field: the new field must also be explicitly defined on the elements.

Member Enumeration Documentation

enum OpenCMISS::Zinc::Node::ChangeFlag

Bit flags summarising changes to a node or nodes in a nodeset.

Enumerator
CHANGE_FLAG_NONE	node(s) not changed
CHANGE_FLAG_ADD	node(s) added
CHANGE_FLAG_REMOVE	node(s) removed
CHANGE_FLAG_IDENTIFIER	node(s) identifier changed
CHANGE_FLAG_DEFINITION	node(s) definition other than identifier changed; currently none
CHANGE_FLAG_FIELD	change to field values mapped to node(s)

enum OpenCMISS::Zinc::Node::ValueLabel

Enumerated labels for field value/derivative parameters held at nodes.

Enumerator
VALUE_LABEL_INVALID	Unspecified node value label
VALUE_LABEL_VALUE	literal field value
VALUE_LABEL_D_DS1	derivative w.r.t. arc length S1
VALUE_LABEL_D_DS2	derivative w.r.t. arc length S2
VALUE_LABEL_D2_DS1DS2	cross derivative w.r.t. arc lengths S1,S2
VALUE_LABEL_D_DS3	derivative w.r.t. arc length S3
VALUE_LABEL_D2_DS1DS3	cross derivative w.r.t. arc lengths S1,S3
VALUE_LABEL_D2_DS2DS3	cross derivative w.r.t. arc lengths S2,S3
VALUE_LABEL_D3_DS1DS2DS3	triple cross derivative w.r.t. arc lengths S1,S2,S3

Member Function Documentation

cmzn_node_id OpenCMISS::Zinc::Node::getId ( ) const

inline

Return the C handle of the Node object.

Returns

C handle of Node if this objects is valid, 0 otherwise.

int OpenCMISS::Zinc::Node::getIdentifier ( )

inline

Returns the non-negative integer uniquely identifying the node in its nodeset.

Returns

The non-negative integer identifier of the node, or a negative value if node is invalid.

Nodeset OpenCMISS::Zinc::Node::getNodeset ( ) const

inline

Get the nodeset which owns this node.

Returns

Handle to the owning nodeset, or NULL/invalid handle on failure.

bool OpenCMISS::Zinc::Node::isValid ( ) const

inline

Check if this is a valid Node object.

Returns

Status True if object is valid, false otherwise.

int OpenCMISS::Zinc::Node::setIdentifier ( int  identifier )

inline

Set an integer uniquely identifying the node in its nodeset.

Parameters

identifier

unique identifier to be set for the node

Returns

OpenCMISS::Zinc::OK if set the identifier successfully, any other value on fail.
