Member Function Documentation

addEssential() [1/2]

void serac::BoundaryConditionManager::addEssential	(	const mfem::Array< int > &	local_dofs,
		std::shared_ptr< mfem::Coefficient >	ess_bdr_coef,
		mfem::ParFiniteElementSpace &	space,
		std::optional< int >	component = {}
	)

Set a list of local degrees of freedom from a scalar coefficient.

Parameters

[in]	local_dofs	Indices of ldofs to set with a Dirichlet condition
[in]	ess_bdr_coef	The scalar coefficient that evaluates to the Dirichlet condition
[in]	space	The finite element space to which the BC should be applied
[in]	component	The component to set (null implies all components are set)

Definition at line 32 of file boundary_condition_manager.cpp.

addEssential() [2/2]

void serac::BoundaryConditionManager::addEssential	(	const std::set< int > &	ess_bdr,
		serac::GeneralCoefficient	ess_bdr_coef,
		mfem::ParFiniteElementSpace &	space,
		const std::optional< int >	component = {}
	)

Set the essential boundary conditions from a list of boundary markers and a coefficient.

Parameters

[in]	ess_bdr	The set of essential BC attributes
[in]	ess_bdr_coef	The essential BC value coefficient
[in]	space	The finite element space to which the BC should be applied
[in]	component	The component to set (null implies all components are set)

Definition at line 15 of file boundary_condition_manager.cpp.

addEssentialByTrueDofs()

void serac::BoundaryConditionManager::addEssentialByTrueDofs	(	const mfem::Array< int > &	true_dofs,
		std::shared_ptr< mfem::VectorCoefficient >	ess_bdr_coef,
		mfem::ParFiniteElementSpace &	space
	)

@ brief Set a list of true degrees of feedom from a vector coefficient

Parameters

[in]	true_dofs	Indices of tdofs to set with a Dirichlet condition
[in]	ess_bdr_coef	The coefficient that evaluates to the Dirichlet condition
[in]	space	The finite element space to which the BC should be applied

allEssentialLocalDofs()

const mfem::Array<int>& serac::BoundaryConditionManager::allEssentialLocalDofs ( ) const

inline

Returns all the local degrees of freedom associated with all the essential BCs.

Returns

A const reference to the list of local DOF indices, without duplicates and sorted

Definition at line 85 of file boundary_condition_manager.hpp.

allEssentialTrueDofs()

const mfem::Array<int>& serac::BoundaryConditionManager::allEssentialTrueDofs ( ) const

inline

Returns all the true degrees of freedom associated with all the essential BCs.

Returns

A const reference to the list of true DOF indices, without duplicates and sorted

Definition at line 73 of file boundary_condition_manager.hpp.

eliminateAllEssentialDofsFromMatrix()

std::unique_ptr<mfem::HypreParMatrix> serac::BoundaryConditionManager::eliminateAllEssentialDofsFromMatrix ( mfem::HypreParMatrix &  matrix ) const

inline

Eliminates all essential BCs from a matrix.

Parameters

[in,out]

matrix

The matrix to eliminate from, will be modified

Returns
