apply_dirichlet_boundary_operator()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::apply_dirichlet_boundary_operator ( const number  time, VectorType &  dst, const VectorType &  src  ) const

inline

Applies the dirichlet contribution of the DG diffusion operator to the src vector and stores the result in the dst vector. The dst vector is NOT zeroed out before the operation. Is not implemented since for a levelset reinitialization, dirichlet boundaries don't make much sense.

apply_operator()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::apply_operator	(	const number	time,
		VectorType &	dst,
		const VectorType &	src,
		const std::function< void(unsigned int, unsigned int)> &	func = {}
	)		const

Applies the DG diffusion operator to the src vector and stores the result in the dst vector. The dst vector is zeroed out before the operation.

Parameters

time
dst	destination vecor where the diffusive part is stored
src	source vector for the operator

compute_diffusitivity_value()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::compute_diffusitivity_value

(

)

Computes the necessary amount of diffusion

The value for the artificial diffusitivity is determined by the smallest enabled element size.

Local diffusitivity value is determined from a local analysis of the characterisc speed

compute_penalty_parameter()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::compute_penalty_parameter

(

)

Computes the necessary penalty parameter

get_max_diffusitivity()

template<int dim, typename number >

number MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::get_max_diffusitivity

(

)

local_apply_boundary_face()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::local_apply_boundary_face ( const dealii::MatrixFree< dim, number > &  data, VectorType &  dst, const VectorType &  src, const std::pair< unsigned int, unsigned int > &  cell_range  ) const

private

Applies the boundary face integral

Parameters

data	the matrix free object
dst	destination where the result is stored
src	source vector
cell_range

local_apply_domain()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::local_apply_domain ( const dealii::MatrixFree< dim, number > &  data, VectorType &  dst, const VectorType &  src, const std::pair< unsigned int, unsigned int > &  cell_range  ) const

private

Applies the domain integral

Parameters

data	the matrix free object
dst	destination where the result is stored
src	source vector
cell_range

local_apply_inner_face()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::local_apply_inner_face ( const dealii::MatrixFree< dim, number > &  data, VectorType &  dst, const VectorType &  src, const std::pair< unsigned int, unsigned int > &  cell_range  ) const

private

Applies the inner face integral

Parameters

data	the matrix free object
dst	destination where the result is stored
src	source vector
cell_range

set_field_functions()

template<int dim, typename number >

void MeltPoolDG::LevelSet::ReinitializationDGDiffusionOperator< dim, number >::set_field_functions ( const number  time ) const

inline

If an analytical function for a field is provided and an analytical update is enabled, this function sets the field according to the analytical function. This function implementation is needed for a time integrator. This function is currently unused

Parameters

time
