Member Function Documentation

◆ ComputeEstimates()

void mfem::TMOPRefinerEstimator::ComputeEstimates ( )
protected

Compute the element error estimates. For an element E in the mesh, error(E) = TMOPEnergy(E)*energy_scaling_factor-Mean(TMOPEnergy(ChildofE)), where TMOPEnergy of Children of E is obtained by assuming the element E is refined using the refinement type being considered based on the TMOP mesh quality metric.

Definition at line 19 of file tmop_amr.cpp.

◆ GetAnisotropicFlags()

virtual const Array< int > & mfem::TMOPRefinerEstimator::GetAnisotropicFlags ( )
inlinevirtual

For anisotropic refinements, get the refinement type (e.g., x or y)

Implements mfem::AnisotropicErrorEstimator.

Definition at line 108 of file tmop_amr.hpp.

◆ GetLocalErrors()

virtual const Vector & mfem::TMOPRefinerEstimator::GetLocalErrors ( )
inlinevirtual

Get TMOP-based errors for each element in the mesh computed based on the refinement types being considered.

Implements mfem::ErrorEstimator.

Definition at line 102 of file tmop_amr.hpp.

◆ GetTMOPRefinementEnergy()

void mfem::TMOPRefinerEstimator::GetTMOPRefinementEnergy ( int reftype,
Vector & el_energy_vec )
protected

Get TMOP energy for each element corresponding to the refinement type specified.

Definition at line 87 of file tmop_amr.cpp.

◆ MeshIsModified()

bool mfem::TMOPRefinerEstimator::MeshIsModified ( )
inlineprotected

Check if the mesh of the solution was modified.

Definition at line 42 of file tmop_amr.hpp.

◆ Reset()

virtual void mfem::TMOPRefinerEstimator::Reset ( )
inlinevirtual

Reset the error estimator.

Implements mfem::ErrorEstimator.

Definition at line 127 of file tmop_amr.hpp.

◆ SetEnergyScalingFactor()

void mfem::TMOPRefinerEstimator::SetEnergyScalingFactor ( real_t scale)
inline

Scaling factor for the TMOP refinement energy. An element is refined if [mean TMOPEnergy(children)]*energy_scaling_factor < TMOPEnergy(parent)

Definition at line 116 of file tmop_amr.hpp.

◆ SetHexIntRules()

void mfem::TMOPRefinerEstimator::SetHexIntRules ( )
protected

Definition at line 182 of file tmop_amr.cpp.

◆ SetIntRulesFromMesh()

IntegrationRule * mfem::TMOPRefinerEstimator::SetIntRulesFromMesh ( Mesh & meshsplit)
protected

Use a mesh to setup an integration rule that will mimic the different refinement types.

Definition at line 317 of file tmop_amr.cpp.

◆ SetQuadIntRules()

void mfem::TMOPRefinerEstimator::SetQuadIntRules ( )
protected

Construct the integration rules to model how each element type is split using different refinement types. ref_type = 0 is the original element and reftype \ in [1, 7] represent different refinement type based on NCMesh class.

Definition at line 206 of file tmop_amr.cpp.

◆ SetSpatialIndicator()

void mfem::TMOPRefinerEstimator::SetSpatialIndicator ( GridFunction & spat_gf_,
real_t spat_gf_critical_ = 0.5 )
inline

Spatial indicator function (eta) that can be used to prevent elements from being refined even if the energy criterion is met. Using this, an element E is not refined if mean(spat_gf(E)) < spat_gf_critical.

Definition at line 121 of file tmop_amr.hpp.

◆ SetSpatialIndicatorCritical()

void mfem::TMOPRefinerEstimator::SetSpatialIndicatorCritical ( real_t val_)
inline

Definition at line 124 of file tmop_amr.hpp.

◆ SetTetIntRules()

void mfem::TMOPRefinerEstimator::SetTetIntRules ( )

Definition at line 274 of file tmop_amr.cpp.

◆ SetTriIntRules()
