Constructor & Destructor Documentation

smith::CoupledSystemSolver::CoupledSystemSolver ( std::shared_ptr< NonlinearBlockSolverBase > single_solver )

Construct a monolithic CoupledSystemSolver from a single block solver.

Parameters

single_solver The solver to use for all blocks simultaneously.

Definition at line 21 of file coupled_system_solver.cpp.

smith::CoupledSystemSolver::CoupledSystemSolver	(	int	max_staggered_iterations,
		bool	exact_staggered_steps = `false`
	)

Construct a CoupledSystemSolver for staggered iteration.

Parameters

max_staggered_iterations	Maximum number of staggered sweeps across all stages. When `exact_staggered_steps` is false, the solver may exit early once all stage solvers report convergence.
exact_staggered_steps	If true, always perform exactly `max_staggered_iterations` sweeps with no early-exit convergence check. Useful when a fixed number of partitioned-stagger steps is required regardless of residual level.

void smith::CoupledSystemSolver::addSubsystemSolver	(	const std::vector< size_t > &	block_indices,
		std::shared_ptr< NonlinearBlockSolverBase >	solver,
		double	relaxation_factor = `1.0`
	)

Convenience method to add a solver stage.

Parameters

block_indices	Indices of the blocks to solve.
solver	Nonlinear block solver for this stage.
relaxation_factor	Per-stage relaxation factor in `(0, 1]`.

Definition at line 33 of file coupled_system_solver.cpp.

std::vector< FieldState > smith::CoupledSystemSolver::solve	(	const std::vector< WeakForm * > &	residual_evals,
		const std::vector< std::vector< size_t >> &	block_indices,
		const FieldState &	shape_disp,
		const std::vector< std::vector< FieldState >> &	states,
		const std::vector< std::vector< FieldState >> &	params,
		const TimeInfo &	time_info,
		const std::vector< const BoundaryConditionManager * > &	bc_managers
	)		const

Solves the multiphysics system using staggered iterations.

Parameters

residual_evals	Vector of WeakForm evaluations for each block.
block_indices	Block indices for each residual evaluation.
shape_disp	Current shape displacement.
states	Nested vector of field states.
params	Nested vector of parameters.
time_info	Current time information.
bc_managers	Managers for boundary conditions.
