Constructor & Destructor Documentation

ElementElementTable::ElementElementTable	(	unsigned long	TotalNumberElements,
		unsigned long	Dimension
	)

Specialized constructor: builds the element-elements topological table for the FE model.

Parameters:

[in]	TotalNumberElements	- total number of elements of the finite element mesh.
[in]	Dimension	- the dimension of the model.

ElementElementTable::ElementElementTable ( ElementElementTable & Instance )

Copies the contents of instance to the object.

Parameters:

[in] Instance - instance of the ElementElementTable class.

Member Function Documentation

void ElementElementTable::BuildElementElementTable	(	FEGroups &	Groups,
		NodeElementTable &	NoElemTable,
		unsigned long	Dimension
	)

Builds the element-element topological table for all finite element groups.

Parameters:

[in]	Groups	- instance of the FEGroups class whichStores information for the finite element groups for the discrete model.
[in]	NoElemTable	- instance of the NodeElementTable.
[in]	Dimension	- the dimension of the model.

void ElementElementTable::Free ( )

Releases the physical memory allocate for the groups.

Note:: Statically allocated variables are set to zero.

long *const ElementElementTable::GetNeighbourElements	(	unsigned long	ElementGlobalNumber,
		unsigned long &	NumberNeighbourElements
	)

Returns a list of elements that are neighbours to a given element.

Parameters:

[in]	ElementGlobalNumber	- the global number of the element for which the neighbour elements are returned.
[out]	NumberNeighbourElements	- number of neighbour elements for the given element number.

Returns:: Pointer to an array of elements.

unsigned long ElementElementTable::GetNumberNeighbours ( unsigned long ElementGlobalNumber )

Returns the number of neighbours for a given element.

Parameters:

[in] ElementGlobalNumber - the global number of the element for which desires to know the number of neighbours.

ElementElementTable & ElementElementTable::operator= ( ElementElementTable & Instance )

Copies the contents of Instance for the object.

Parameters:

[in] Instance - instance of ElementElementTable.

Returns:: Reference of the current object.

void ElementElementTable::Print	(	FILE *	File,
		char *	Message = `""`
	)

Prints the parameters of the FE groups to an ASCII file.

Parameters:

[in]	File	- pointer to the ASCII file.
[in]	Message	- optional message to be written to the ASCII file.

void ElementElementTable::Restore	(	char *	Tabname,
		int	Version,
		char *	Filename
	)

Restores class data (written using the Save method) from a binary file.

Parameters:

[in]	Tabname	- name of the database table where the data will be stored.
[in]	Version	- data version number.
[in]	Filename	- database prefix filename. Two files will be used: filename.dir and filename.bdg. The first one stores keys to the data stored in the filename.bdg file.

void ElementElementTable::Restore ( FILE * File )

Restores class data (written using Save()) form a binary file.

Parameters:

[in] File - pointer to the binary file.

void ElementElementTable::Save	(	char *	Tabname,
		int	Version,
		char *	Filename
	)

Writes class data to a binary database.

Parameters:

[in]	Tabname	- name of the database table where the data will be stored.
[in]	Version	- data version number.
[in]	Filename	- database prefix filename. Two files will be used: filename.dir and filename.bdg. The first one stores keys to the data stored in the filename.bdg file.

void ElementElementTable::Save ( FILE * File )

Writes class information to a binary file.

Note:: The current object state can be completely recovered when applying the Restore() operation.

Parameters:

[in] File - pointer to the binary file.
