[Paraview] plot over line question (save data)

[Sven Buijssen]

Stephen,

There is no built-in solution as far as I know, but the following pipeline may
serve as a guideline:

* Apply ’Extract Block’ and ’Merge Blocks’ filter for a multi-block data set
* Apply Programmable Filter with the following Python source code:

inp = self.GetInput()
filename = "foo.csv"
FILE = open(filename, "w")
FILE.write("x,y,z, x-velocity\n")
numPoints = inp.GetNumberOfPoints()
vel = inp.GetPointData().GetArray("velocity")
for i in xrange(0, numPoints):
  coords = inp.GetPoint(i)[:3]
  FILE.write(str(coords[0]) + ",")
  FILE.write(str(coords[1]) + ",")
  FILE.write(str(coords[2]) + ",")
  FILE.write(str(vel.GetValue(i * 3)) + "\n")
FILE.close()
