Detailed Description

Base class for creating MeshOps that call Mesquite smoother.

This class can be used to either create a MeshOp from any custom Mesquite algorithm or Mesquite wrapper, or as a base class for MeshOp classes that implement a specific Mesquite algorithm.

		iBase_EntityType &	dimension,
		bool &	created_result_set
	)		`[protected]`

Helper function for free smooth of multiple entities.

For proper results when doing a free smooth of multiple model entities, the mesh for all model entities connected by a curve or surface should be smoothed together. This finds a single connected group of ModelEnts in from_this, removes them from from_this, and creates a single iBase_EntitySetHandle containing the mesh of all of the ModelEnts in the connected set.

Parameters:

from_this	Set of ModelEnts in which to search for a group of connected ModelEnts. Connected ModelEnts are _removed_ from the passed MEntSet.
smooth_ents	List of connected entities that are to be smoothed together.
result	An iBase_EntitySetHandle corresponding to a set that contains all of the mesh entities of all of the connected ModelEnts removed from `from_this`
dimension	If all connected ModelEnts have the same dimension, that dimension. Otherwise iBase_ALL_TYPES.
created_result_set	True if the function created a new iBase_EntitySetHandle. Will be false if the set corresponds to a single ModelEnt that was connected to no others, in which case the returned set is just that of the ModelEnt.

iBase_TagHandle get_fixed_tag ( )

Get handle of tag used to designate vertices as fixed.

Definition at line 61 of file MesquiteOpt.cpp.

virtual const moab::EntityType* mesh_types_arr ( ) const [inline, virtual]

Return the mesh entity types operated on by this scheme.

Returns:: array terminated with moab::MBMAXTYPE

Implements MeshOp.

const char * name ( ) [inline, static]

void print_quality ( bool yesno ) [inline]

void set_fixed_tag ( iBase_TagHandle tag )

Set handle of tag used to designate vertices as fixed.

Definition at line 68 of file MesquiteOpt.cpp.

void set_fixed_tag ( const char * name )

Set handle of tag used to designate vertices as fixed.

Tag will be created if it does not already exists. If tag already exists then it must be a single integer value.

Definition at line 80 of file MesquiteOpt.cpp.

void set_fixed_tag	(	ModelEnt *	ent,
		int	value
	)		`[protected]`

Set fixed tag on vertices of ModelEnt's mesh entities.

Parameters:

ent	Entity for which to set 'fixed' tag on vertices of all owned elements.
value	Value to set 'fixed' tag to. Should be either zero or one, corresponding to free or fixed, respectively.

Definition at line 145 of file MesquiteOpt.cpp.

void set_fixed_tag_on_skin	(	ModelEnt *	ent,
		int	value
	)		`[protected]`

Set fixed tag on boundary of ModelEnt's mesh.

Parameters:

ent	Entity for which to set 'fixed' tag on vertices of boundary
value	Value to set 'fixed' tag to. Should be either zero or one, corresponding to free or fixed, respectively.

Definition at line 176 of file MesquiteOpt.cpp.

void set_irel_both_relation ( ) [protected]

Change relation on iMesh side to BOTH-type.

Doing a free smooth of geometry with Mesquite requires that Mesquite be able to query iRel for a iGeom handle corresponding to vertex and elemet handles. This requires a 'BOTH' relation on the iMesh side.

void set_mesquite_op ( Mesquite::IQInterface * msq_algo ) [inline]

specify mesquite optimization algorithm to execute

Definition at line 27 of file MesquiteOpt.hpp.

void setup_this ( ) [virtual]

Pure virtual, derived class must define.

Implements GraphNode.

Examples:: example_mesquiteopt.cpp.

Definition at line 139 of file MesquiteOpt.cpp.

void smooth_with_fixed_boundary ( )

smooth only interior of mesh

This is the default behavior

Examples:: example_mesquiteopt.cpp.

Definition at line 125 of file MesquiteOpt.cpp.

void smooth_with_free_boundary ( )

smooth interior and exiterior of mesh

This method will throw an exception if Mesquite is configured w/out iRel support or the boundary of the mesh is not constrained to geometric entities.
