Hello,
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[0].CellData.GetArray('RegionId').GetRange()
for ic in range(int(rangeID[0]), int(rangeID[1])):
thresh.ThresholdBetween(ic-0.5,ic+0.5)
thresh.Update()
tooutData = thresh.GetOutputDataObject(0)
outData.SetBlock(ic,tooutData)
out.DeepCopy(outData)
