Constructor & Destructor Documentation

AlgoimIntegrationRules()

mfem::AlgoimIntegrationRules::AlgoimIntegrationRules ( int order, Coefficient & lvlset, int lsO = 2 )

inline

Constructor to set up the generated cut IntegrationRules.

Parameters

[in]	order	Order of the constructed IntegrationRule.
[in]	lvlset	Coefficient whose zero level set specifies the cut.
[in]	lsO	Polynomial degree for projecting the level-set Coefficient to a GridFunction, which is used to compute gradients and normals.

Member Function Documentation

GetSurfaceIntegrationRule()

void mfem::AlgoimIntegrationRules::GetSurfaceIntegrationRule ( ElementTransformation & Tr, IntegrationRule & result )

overridevirtual

Construct a cut-surface IntegrationRule.

Construct an IntegrationRule to integrate on the surface given by the already specified level set function, for the element given by Tr.

Parameters

[in]	Tr	Specifies the IntegrationRule's associated mesh element.
[out]	result	IntegrationRule on the cut-surface

Implements mfem::CutIntegrationRules.

Definition at line 35 of file intrules_cut.cpp.

GetSurfaceWeights()

void mfem::AlgoimIntegrationRules::GetSurfaceWeights ( ElementTransformation & Tr, const IntegrationRule & sir, Vector & weights )

overridevirtual

Compute transformation quadrature weights for surface integration.

Compute the transformation weights for integration over the cut-surface in reference space.

Parameters

[in]	Tr	Specifies the IntegrationRule's associated element.
[in]	sir	IntegrationRule defining the IntegrationPoints
[out]	weights	Vector containing the transformation weights.

Implements mfem::CutIntegrationRules.

Definition at line 111 of file intrules_cut.cpp.

GetVolumeIntegrationRule()

void mfem::AlgoimIntegrationRules::GetVolumeIntegrationRule ( ElementTransformation & Tr, IntegrationRule & result, const IntegrationRule * sir = nullptr )

overridevirtual

Construct a cut-volume IntegrationRule.

Construct an IntegrationRule to integrate in the subdomain given by the positive values of the already specified level set function, for the element given by Tr.

Parameters

[in]	Tr	Specifies the IntegrationRule's associated mesh element.
[out]	result	IntegrationRule for the cut-volume
[in]	sir	Corresponding IntegrationRule for the surface, which can be used to avoid computations.

Implements mfem::CutIntegrationRules.
