Detailed Description

template<int dim, int degree>
class FloodFiller< dim, degree >

This class uses a recursive flood filling algorithm to find connected bodies in a field, given a threshold. The MPI communication methods are similar to those in parallelNucleationList.

Constructor & Destructor Documentation

FloodFiller()

Constructor.

Member Function Documentation

calcGrainSets()

template<int dim, int degree>

void FloodFiller< dim, degree >::calcGrainSets	(	dealii::FESystem< dim > &	finite_element,
		dealii::DoFHandler< dim > &	dof_handler,
		dealii::LinearAlgebra::distributed::Vector< double > *	solution_field,
		double	threshold_lower,
		double	threshold_upper,
		int	min_id,
		unsigned int	order_parameter_index,
		std::vector< GrainSet< dim > > &	grain_sets
	)

The primary external interface. This method takes in information about the mesh/field and outputs a vector of GrainSet objects.

createGlobalGrainSetList()

template<int dim, int degree>

void FloodFiller< dim, degree >::createGlobalGrainSetList ( std::vector< GrainSet< dim > > &  grain_sets ) const

protected

The method to merge the grain sets from all the processors.

mergeSplitGrains()

template<int dim, int degree>

void FloodFiller< dim, degree >::mergeSplitGrains ( std::vector< GrainSet< dim > > &  grain_sets ) const

protected

Checks to see if grains found on different processors are parts of a larger grain. If so, it merges the grain_sets entries.

recursiveFloodFill()

template<int dim, int degree>

template<typename T >

void FloodFiller< dim, degree >::recursiveFloodFill ( T  cell, T  cell_end, dealii::LinearAlgebra::distributed::Vector< double > *  solution_field, double  threshold_lower, double  threshold_upper, int  min_id, unsigned int &  grain_index, std::vector< GrainSet< dim > > &  grain_sets, bool &  grain_assigned  )

protected

The actual recursive flood fill method.

Member Data Documentation

dofs_per_cell

template<int dim, int degree>

const unsigned int FloodFiller< dim, degree >::dofs_per_cell

protected

The number of degrees of freedom per cell.

fe

template<int dim, int degree>

dealii::FESystem<dim>* FloodFiller< dim, degree >::fe

protected

The deal.II finite element object, set in the constructor.

num_quad_points

template<int dim, int degree>

const unsigned int FloodFiller< dim, degree >::num_quad_points

protected

The number of quadrature points per cell.

quadrature

template<int dim, int degree>

dealii::QGaussLobatto<dim> FloodFiller< dim, degree >::quadrature

protected

The quadrature used to calculate the element-wise value of the solution field.
