Detailed Description

Base class representing target-matrix construction algorithms for mesh optimization via the target-matrix optimization paradigm (TMOP).

This class is used by class TMOP_Integrator to construct the target Jacobian matrices (reference-element to target-element) at quadrature points. It supports a set of algorithms chosen by the TargetType enumeration.

New target-matrix construction algorithms can be defined by deriving new classes and overriding the method ComputeElementTargets().

Member Enumeration Documentation

enum mfem::TargetConstructor::TargetType

Target-matrix construction algorithms supported by this class.

Enumerator
IDEAL_SHAPE_UNIT_SIZE	Ideal shape, unit size; the nodes are not used.
IDEAL_SHAPE_EQUAL_SIZE	Ideal shape, equal size/volume; the given nodes define the total target volume; for each mesh element, the target volume is the average volume multiplied by the volume scale, set with SetVolumeScale().
IDEAL_SHAPE_GIVEN_SIZE	Ideal shape, given size/volume; the given nodes define the target volume at all quadrature points.
GIVEN_SHAPE_AND_SIZE	Given shape, given size/volume; the given nodes define the exact target Jacobian matrix at all quadrature points.

void mfem::TargetConstructor::SetNodes ( const GridFunction & n )

inline

Set the nodes to be used in the target-matrix construction.

This method should be called every time the target nodes are updated externally and recomputation of the target average volume is needed. The nodes are used by all target types except IDEAL_SHAPE_UNIT_SIZE.

Definition at line 470 of file tmop.hpp.

void mfem::TargetConstructor::SetVolumeScale ( double vol_scale )

inline

Used by target type IDEAL_SHAPE_EQUAL_SIZE. The default volume scale is 1.
