[Paraview] questions re VTK-formatted file

[Randy Heiland]

I have some questions related to a specific datafile format (simple example below).

Q1:  what exactly is displayed by default when this file is opened?
Q2:  I can't seem to use a Contour filter on the data - is the format of the file causing problems or something else?
Q3:  how does one force output results to go to an existing window, rather than opening a new one?

Here's a link with the same questions and some accompanying pics:

thanks, Randy
