Constructor & Destructor Documentation

NURBSMeshRules()

mfem::NURBSMeshRules::NURBSMeshRules ( const int numPatches, const int dim_ )

inline

Construct a rule for each patch, using SetPatchRules1D.

Member Function Documentation

AddElementRule()

std::size_t mfem::NURBSMeshRules::AddElementRule ( IntegrationRule * ir_element )

inline

Add a rule to be used for individual elements. Returns the rule index.

Definition at line 293 of file intrules.hpp.

Finalize()

void mfem::NURBSMeshRules::Finalize

(

Mesh const &

mesh

)

Finalize() must be called before this class can be used for assembly. In particular, it defines data used by GetPointElement().

Definition at line 1970 of file intrules.cpp.

GetDim()

int mfem::NURBSMeshRules::GetDim ( ) const

inline

Definition at line 339 of file intrules.hpp.

GetElementRule()

IntegrationRule & mfem::NURBSMeshRules::GetElementRule	(	const int	elem,
		const int	patch,
		const int *	ijk,
		Array< const KnotVector * > const &	kv,
		bool &	deleteRule ) const

Returns a rule for the element.

Definition at line 1865 of file intrules.cpp.

GetIntegrationPointFrom1D()

void mfem::NURBSMeshRules::GetIntegrationPointFrom1D	(	const int	patch,
		int	i,
		int	j,
		int	k,
		IntegrationPoint &	ip )

For tensor product rules defined on each patch by SetPatchRules1D(), return the integration point with index (i,j,k).

Definition at line 1948 of file intrules.cpp.

GetPatchRule1D()

const IntegrationRule * mfem::NURBSMeshRules::GetPatchRule1D ( const int patch, const int dimension ) const

inline

For tensor product rules defined on each patch by SetPatchRules1D(), return a pointer to the 1D rule in the specified dimension.

Definition at line 315 of file intrules.hpp.

GetPatchRule1D_KnotSpan()

const Array< int > & mfem::NURBSMeshRules::GetPatchRule1D_KnotSpan ( const int patch, const int dimension ) const

inline

For tensor product rules defined on each patch by SetPatchRules1D(), returns an array of knot span indices for each integration point in the specified dimension.

Definition at line 344 of file intrules.hpp.

GetPointElement()

int mfem::NURBSMeshRules::GetPointElement ( int patch, int i, int j, int k ) const

inline

For tensor product rules defined on each patch by SetPatchRules1D(), returns the index of the element containing integration point (i,j,k) for patch index patch. Finalize() must be called first.

Definition at line 334 of file intrules.hpp.

SetElementRule()

void mfem::NURBSMeshRules::SetElementRule ( const std::size_t element, const std::size_t elementRuleIndex )

inline

Set the integration rule for the element of the given index. This rule is used instead of the rule for the patch containing the element.

Definition at line 301 of file intrules.hpp.

SetPatchRules1D()

void mfem::NURBSMeshRules::SetPatchRules1D	(	const int	patch,
		std::vector< const IntegrationRule * > &	ir1D )

Set 1D integration rules to be used as a tensor product rule on the patch with index patch. This class takes ownership of these rules.
