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 on curvilinear mesh).
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 .
virtual const std::vector< const MeXScalardSetI* >& MiStreamlineExtractIjk::extractScalarSet | ( | const MiScalardSetIjk & | inputSet | ) | [pure virtual] |
Extracts from the mesh a list of scalar sets.
The scalars are mapped onto the current extracted streamlines. If the dataset is binded PER_NODE the scalars are interpolated and one scalar is binded per node of the extracted streamlines. Otherwise one scalar is binded per edge of the extracted streamlines.
inputSet | the input scalar set defined on the original volume mesh |
Implemented in MiStreamlineExtractHexahedronIjk.

const std::vector< MbVec3d > & | startPoints, | |||
const MiCellFilterIjk * | cellFilter = NULL | |||
) | [pure virtual] |
Builds the topology and geometry of the streamlines starting at the given points in the given dataset.
inputdataset | Defines the vector field for the streamlines integration. | |
startPoints | Defines the list of start points for the streamlines integration. | |
cellFilter | The call filter. |
