Constructor & Destructor Documentation

IfpackPrecond::IfpackPrecond	(	const char *	cls,
		const char *	type = "Jacobi"
	)

Constructor for relaxation methods.

Parameters:

[in]	cls	- class of the preconditioner [ point-relax | block-relax ]
[in]	name	- the name of the relaxation type Possible values are: [ Jacobi | Gauss-Seidel | symmetric Gauss-Seidel ]

IfpackPrecond::IfpackPrecond	(	const char *	cls,
		const char *	type,
		int	overlap
	)

Constructor for domain decomposition methods.

Parameters:

[in]	cls	- class of the preconditioner [ add-schwartz ]
[in]	name,:	[ ic | ict | ilu | ilut ]
[in]	overlap	- number
