Constructor & Destructor Documentation

serac::SuperLUSolver::SuperLUSolver	(	int	print_level,
		MPI_Comm	comm
	)

inline

Constructs a wrapper over an mfem::SuperLUSolver.

Parameters

[in]	comm	The MPI communicator used by the vectors and matrices in the solve
[in]	print_level	The verbosity level for the mfem::SuperLUSolver

Definition at line 159 of file equation_solver.hpp.

void serac::SuperLUSolver::Mult	(	const mfem::Vector &	input,
		mfem::Vector &	output
	)		const

Factor and solve the linear system y = Op^{-1} x using DSuperLU.

Parameters

input	The input RHS vector
output	The output solution vector

Definition at line 911 of file equation_solver.cpp.

void serac::SuperLUSolver::SetOperator ( const mfem::Operator & op )

Set the underlying matrix operator to use in the solution algorithm.

Parameters

op	The matrix operator to factorize with SuperLU

Precondition: This operator must be an assembled HypreParMatrix or a BlockOperator with all blocks either null or HypreParMatrixs for compatibility with SuperLU
