[Paraview] Trouble making stream traces

[John Fettig]

Berk,

I have verified that my connectivity is correct.  I have attached a much
smaller file, only 15 nodes and 4 elements.  Still has problem doing
streamtraces.  Guess I'm gonna go back to 4xlinear quads.  Would be nice
if there was a 9-noded quad...

John
