Bases: object

Handles the conversion of multiple vtkPartitionedDataSetCollections, where each vtkPartitionedDataSetCollection contains a grid for a single time step.

__init__(vtk_objects: list[vtkmodules.vtkCommonDataModel.vtkPartitionedDataSetCollection], ids_name, dd_version=None, cylindrical_coordinates=False)¶

Methods

__init__(vtk_objects, ids_name[, ...])
convert()	Converts a list of vtkPartitionedDataSetCollections into a single IDS.
extract_data_from_pdsc(vtk_pdsc)	Extract point coordinates and cell connectivities grouped by dimension from a vtkPartitionedDataSetCollection.
