Detailed Description

Cache for setting domain locations at which fields are evaluated or assigned.

Cache for setting domain locations at which fields are to be evaluated or assigned, and for storing intermediate values and data structures so that multiple evaluations are more efficient.

Member Function Documentation

int OpenCMISS::Zinc::Fieldcache::clearLocation ( )

inline

Clears domain locations held in the field cache. Call this function before evaluating fields in a different domain (e.g. nodes <-> elements <-> point) to ensure false field values at the last domain location are not returned. Note that all domain locations are cleared by this function including time which is reset to 0.0, so these need to be set again if needed.

Returns: Status OpenCMISS::Zinc::OK on success, otherwise OpenCMISS::Zinc::ERROR_ARGUMENT.

cmzn_fieldcache_id OpenCMISS::Zinc::Fieldcache::getId ( ) const

inline

Return the C handle of the Fieldcache object.

Returns: C handle of Fieldcache if this objects is valid, 0 otherwise.

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

inline

Check if this is a valid Fieldcache object.

Returns: Status True if object is valid, false otherwise.

int OpenCMISS::Zinc::Fieldcache::setElement ( const Element & element )

inline

Prescribes an element location without specifying chart coordinates. Suitable only for evaluating fields that are constant across the element. Note: replaces any other spatial location in cache (e.g. node.) but time is unchanged.

Parameters

element The element to set. Must belong to same region as cache.

Returns: Status OpenCMISS::Zinc::OK on success, any other value on failure.

int OpenCMISS::Zinc::Fieldcache::setFieldReal	(	const Field &	referenceField,
		int	valuesCount,
		const double *	valuesIn
	)

inline

Prescribes a value of a field for subsequent evaluation and assignment with the cache. Note: currently treated as a spatial location, replacing any other spatial location in cache (e.g. element, node) but time is unchanged.

Parameters

referenceField	The field whose values are to be prescribed.
valuesInCount	The size of the values array. Can be less than the number of field components, and if so it is padded with zeroes.
valuesIn	The field values to set.

Returns: Status OpenCMISS::Zinc::OK on success, any other value on failure.

int OpenCMISS::Zinc::Fieldcache::setMeshLocation	(	const Element &	element,
		int	coordinatesCount,
		const double *	coordinatesIn
	)

inline

Prescribes a location in an element for field evaluation or assignment with the cache. Note: replaces any other spatial location in cache (e.g. node.) but time is unchanged.

Parameters

element	The element the location is in. Must belong to same region as cache.
coordinatesCount	The size of the chart_coordinates array, checked to be not less than the element dimension.
coordinatesIn	Location in element chart. Value is not checked; caller is responsible for supplying locations within the bounds of the element shape.

Returns: Status OpenCMISS::Zinc::OK on success, any other value on failure.

int OpenCMISS::Zinc::Fieldcache::setNode ( const Node & node )

inline

Prescribes a node location for field evaluation or assignment with the cache. Note: replaces any other spatial location in cache (e.g. element) but time is unchanged.

Parameters

node	The node to set as spatial location. Must belong to same region as cache.

Returns: Status OpenCMISS::Zinc::OK on success, any other value on failure.

int OpenCMISS::Zinc::Fieldcache::setTime ( double time )

inline

Prescribes the time for field evaluation or assignment with the cache.

Parameters

time	The time value to be set.

Returns: Status OpenCMISS::Zinc::OK on success, any other value on failure.
