const unsigned int & _min_iter
minimum number of power iterations
InversePowerMethod(const InputParameters ¶meters)
const bool & _cheb_on
indicating if Chebyshev acceleration is turned on
const unsigned int & _max_iter
maximum number of power iterations
virtual void execute() override
Pure virtual execute function MUST be overridden by children classes.
static InputParameters validParams()
const PostprocessorName & _solution_diff_name
name of the postprocessor for evaluating |x-xprevious|; empty means that no postprocessor is provided...
const Real & _l_tol
tolerance on each power iteration (always one nonlinear iteration)
This class provides reusable routines for eigenvalue executioners.
const Real & _sol_check_tol
convergence tolerance on solution difference
bool _last_solve_converged
flag to indicate if inverse power iteration converged
DIE A HORRIBLE DEATH HERE typedef LIBMESH_DEFAULT_SCALAR_TYPE Real
virtual bool lastSolveConverged() const override
Whether or not the last solve converged.
const InputParameters & parameters() const
Get the parameters of the object.
const Real & _eig_check_tol
convergence tolerance on eigenvalue
virtual void init() override
Initialize the executioner.
