[Paraview] Getting the coordinates of the point with max temperature

[David E DeMarle]

The arrays themselves may be extremely large, thus they live on the
server, not the client and you can't get them directly as you are
trying to do.
You can however use servermanager.Fetch to bring them over, but you
should only do so once you have filtered them down in size a bit.
Try using the threshold filter, picking out only those cells/points
near the maximum, then fetching that.
