I am new for VTK. I have loaded one vtk file in paraview which have the multiblock data set in it and it have cells and faces in it (unstructured grid). I have filed data as will in it. I want to divide this cells and faces based on filed data i exported.
As an example cells have domain id in range [4,100] in cells and i exported field data domain id vs name i.e. domain id 4 has the name of inlet. now i want to divide cells based on domain id and give its name same as what is corresponding to filed data.
It is now:
I want something like:
i was using following script as a reference:
import vtk inp = self.GetInputDataObject(0, 0) out = self.GetOutput() outData = vtk.vtkMultiBlockDataSet() thresh = vtk.vtkThreshold() thresh.SetInputData(inp) thresh.SetInputArrayToProcess(0,0,0,vtk.vtkDataObject.FIELD_ASSOCIATION_CELLS,'RegionId') rangeID = inputs.CellData.GetArray('RegionId').GetRange() for ic in range(int(rangeID), int(rangeID)): thresh.ThresholdBetween(ic-0.5,ic+0.5) thresh.Update() tooutData = thresh.GetOutputDataObject(0) outData.SetBlock(ic,tooutData) out.DeepCopy(outData)
