Detailed Description

UMFPACK based solver implementation.

An implementation of virtual class Solver using UMFPACK matrix solver library doing LU decomposition to solve linear matrix problems. This solver includes both linear and nonlinear solvers. Nonlinear solver based on Newton-Raphson iteration.

Todo:: Should this solver have a flag to use globally convergent version?

Destructor.

Member Function Documentation

virtual void UMFPACKSolver::reset ( void ) [virtual]

Reset solver.

This is a signal from the problem that the problem has changed and internal caches (if they exist) in the solver should be resetted.

Implements Solver.

void UMFPACKSolver::set_newton_imax ( uint32_t newton_imax ) [inline]

Sets maximum iteration count for Newton-Raphson steps.

void UMFPACKSolver::set_newton_residual_eps ( double newton_Reps ) [inline]

Sets the accuracy request for Newton-Raphson residual.

void UMFPACKSolver::set_newton_step_eps ( double newton_dXeps ) [inline]

Sets the accuracy request for Newton-Raphson step size.

virtual void UMFPACKSolver::solve	(	const Problem &	p,
		Vector &	X
	)			`[virtual]`

Solve problem p defined in geometry g. Initial guess and solution are in vector X.
