[Paraview] Looping over blocks in a multiblock data set and printing to a table or graph

[Utkarsh Ayachit]

It'll be something like follows:

Programmable Filter: OutputDataSetType= "vtkTable".
==============================================
Script
==============================================
import numpy as np

size = 0
for input_block  in inputs[0]:
  size += 1
meanArray = np.zeros(size, dtype = np.float64)

index = 0
for input_block  in inputs[0]:
  mean = np.mean(input_block.PointData["Elevation"])
  meanArray[index] = mean
  index += 1
output.RowData.append(meanArray, "MeanElevation")

A 4.3.1 state file attached.
