class PowerIterationKEigenSolver : public opensn::DiscreteOrdinatesSolver

Public Functions

explicit PowerIterationKEigenSolver(const InputParameters &params)
inline double GetEigenvalue() const

Return the current k-eigenvalue.

inline double GetKTolerance() const

Return the k-eigenvalue convergence tolerance.

inline unsigned int GetNumPowerIterations() const

Return the number of completed power iterations.

std::size_t GetNumSweeps() const

Return the total number of transport sweeps applied by all WGS solvers.

BalanceTable ComputeBalanceTable() const
void SetLBSFissionSource(const std::vector<double> &input, bool additive)

Combines function calls to set fission source.

void SetLBSScatterSource(const std::vector<double> &input, bool additive, bool suppress_wg_scat = false)

Combines function calls to set scattering source source.

Public Static Functions

static InputParameters GetInputParameters()
static std::shared_ptr<PowerIterationKEigenSolver> Create(const ParameterBlock &params)

Protected Functions

virtual void CheckRequirements(std::vector<std::string> &errors) const override

Appends one message for each solver-specific requirement the problem violates.

Problem-wide rules belong in DiscreteOrdinatesProblem::CheckConfigurationErrors. Requirements based on rank-local state reduce it before appending an error.

virtual void InitializeSolver() override

Performs derived-class initialization after ValidateState() succeeds.

virtual void ExecuteSolver() override

Performs derived-class execution after initialization and validation succeed.
