Class MiStreamlineExtractHexahedronIjk
- All Implemented Interfaces:
MiBaseExtractor
,MiExtractorIjk
,MiStreamlineExtractBase
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.

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 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 callingMiStreamlineExtractIjk.getExtract()
.- Parameters:
inputDataSet
- defines the vector field for the streamlines integrationcellFilter
- the cell filterstartPoints
- defines the list of start points {x,y,z} for the streamlines integration- Returns:
- the extracted streamlines as curvilinear line meshes
-
extractScalarSet
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 bePER_NODE
. AnUnsupportedOperationException
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
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 bePER_NODE
. AnUnsupportedOperationException
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
