public abstract class MiStreamlineExtractHexahedronIjk
extends MiStreamlineExtractIjk

Streamline extractor for hexahedron IJK meshes.

Builds a list of MiLineMeshCurvilinear interfaces containing streamlines starting from a list of source points and probes the input mesh to compute the values at the streamline nodes (See MiPointProbeUnstructured for settings).
A streamline is a line that is everywhere tangent to a vector field. Streamlines are meaningless for unsteady flow, because time is not taken into account during the computation of the line. Streamlines are integrated from a given set of vectors using a Runge/Kutta method of order 2.

Method Detail

getNewInstance

public static <T extends MiHexahedronTopologyExplicitIjk,G extends MiGeometryI> MiStreamlineExtractHexahedronIjk getNewInstance(MiVolumeMeshHexahedronIjk<T,G> mesh)

Create an instance of a streamlines extractor for an IJK Hexahedron volume mesh.

Parameters:

mesh - the input mesh

Returns:

a streamlines extractor for an IJK Hexahedron volume mesh

extractStreamlines

public abstract java.util.List<MeXLineMeshCurvilinear<MeXTopologyI,MeXGeometryI>> extractStreamlines(MiVec3dSetI inputDataSet,
                                                                                                     MiCellFilterIjk cellFilter,
                                                                                                     double[]... startPoints)

Builds the topology and geometry of the streamlines starting at the given points in the given dataset. The resulting streamlines can be retrieved by calling MiStreamlineExtractIjk.getExtract().

Parameters:

inputDataSet - defines the vector field for the streamlines integration

cellFilter - the cell filter

startPoints - defines the list of start points {x,y,z} for the streamlines integration

Returns:

the extracted streamlines as curvilinear line meshes

extractScalarSet

public abstract java.util.List<MeXScalardSetI> extractScalarSet(MiScalardSetI inputSet)

Extracts from the mesh a list of scalar sets.
The scalars are mapped onto the current extracted streamlines.

Note: The argument i of the method MiScalardSetI.get(long) refers to the i-th node of the mesh. Thus the binding of the input set must be PER_NODE. An UnsupportedOperationException is thrown otherwise.

Parameters:

inputSet - the input scalar set defined on the original volume mesh

Returns:

the output scalar sets defined on the resulting edge meshes

extractVec3Set

public abstract java.util.List<MeXVec3dSetI> extractVec3Set(MiVec3dSetI inputSet)

Extracts from the mesh a list of vector sets.
The vectors are mapped onto the current extracted streamlines.

Note: The argument i of the method MiVec3dSetI.get(long) refers to the i-th node of the mesh. Thus the binding of the input set must be PER_NODE. An UnsupportedOperationException is thrown otherwise.

Parameters:

inputSet - the input vector set defined on the original volume mesh

Returns:

the output vector sets defined on the resulting edge meshes
