Detailed Description

MeshViz Grid plane slice extractor on unstructured volume meshes

This extractor is similar to the plane slice extractor except that it creates a structured mesh and probes the input volume to compute the values at the surface nodes and cells (See MiPointProbeUnstructured for settings). The grid created by this extractor is computed so that it encloses completely the cross section of the input volume mesh marking as dead the cells outside the volume.

◆ extractGrid()

virtual const MeXSurfaceMeshCurvilinear & MiGridPlaneSliceExtractUnstructured::extractGrid ( const MbVec3< double > &  normal,
double  distance,
double  step,
const MiCellFilterI cellFilter = NULL 
)
pure virtual

Builds the topology and geometry of a curvilinear surface mesh defined by the given plane normal and distance to origin.

This grid is computed so that it encloses completely the cross section of the input volume mesh.

Parameters
normalVector normal to the grid plane slice
distancePosition of the plane relatively to the origin along the normal
stepDistance between two consecutive nodes in both directions of the plane
cellFilterThe cell filter object.
Returns
A curvilinear surface mesh representing the grid plane slice

◆ extractScalarSet()

virtual const MeXScalardSetIj & MiGridPlaneSliceExtractUnstructured::extractScalarSet ( const MiScalardSetI inputSet)
pure virtual

Extracts a PER_NODE scalar set from the volume mesh.

The scalars are mapped onto the current extracted grid. Even if the binding of the input scalar set is PER_CELL, this extractor cannot produce a PER_CELL extract because it uses the probing mechanism at each grid plane node to extract values and so does not contain PER_CELL values.

Parameters
inputSetthe input scalar set defined on the volume mesh
Returns
the output scalar set defined on the resulting grid volume mesh

◆ extractVec3Set()

virtual const MeXVec3dSetIj & MiGridPlaneSliceExtractUnstructured::extractVec3Set ( const MiVec3dSetI inputSet)
pure virtual

Extracts a PER_NODE vector set from the volume mesh.

The vectors are mapped onto the current extracted grid. Even if the binding of the input vector set is PER_CELL, this extractor cannot produce a PER_CELL extract because it uses the probing mechanism at each grid plane node to extract values and so does not contain PER_CELL values.

Parameters
inputSetthe input vec3 set defined on the volume mesh
Returns
the output scalar set defined on the resulting grid volume mesh

◆ getExtract()

virtual const MeXSurfaceMeshCurvilinear & MiGridPlaneSliceExtractUnstructured::getExtract ( ) const
pure virtual

Returns the result of the extraction as a mesh.

◆ getNewInstance()

static MiGridPlaneSliceExtractUnstructured * MiGridPlaneSliceExtractUnstructured::getNewInstance ( const MiVolumeMeshUnstructured mesh,
bool  parallel = true,
MiTessellator tessellator = NULL 
)
static

Factory method returning a new instance of a class implementing this abstract class.

Parameters
meshThe input mesh
parallelWhen true, tries to create an extract module using a parallel algorithm to speed up the extraction.
tessellatorThe tessellator object used for tessellating non linear cells (quadratic,...).
Note
Only some of the extraction algorithms have a parallel implementation.
