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?

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.
