int fei::LinearSystem::loadEssentialBCs	(	int	numIDs,
		const int *	IDs,
		int	idType,
		int	fieldID,
		int	offsetIntoField,
		const double *	prescribedValues
	)

virtual

Essential boundary-condition function that simply accepts a list of prescribed values, rather than the 'old' FEI's confusing approach of accepting arrays of alpha, beta and gamma values that nobody every really understood.

For each specified ID, a value is being prescribed for a specified fieldID and a specified offset into that field.

Parameters

numIDs
IDs
idType
fieldID
offsetIntoField
prescribedValues	Input. List of values. Has length numIDs.

Reimplemented in snl_fei::LinearSystem_General.

Definition at line 70 of file fei_LinearSystem.cpp.

		const int *	IDs,
		int	idType,
		int	fieldID,
		const int *	offsetsIntoField,
		const double *	prescribedValues
	)

virtual

Essential boundary-condition function that simply accepts a list of prescribed values, rather than the 'old' FEI's confusing approach of accepting arrays of alpha, beta and gamma values that nobody every really understood.

For each specified ID, a value is being prescribed for a specified fieldID and a specified offset into that field. The offset into the field can be different for each prescribed value.

Parameters

numIDs
IDs
idType
fieldID
offsetsIntoField	Input. List of values, length numIDs.
prescribedValues	Input. List of values. Has length numIDs.
