Hi,

I am a new user of paraview and try to understand .vtu file format. 
Just as a simple test I wanted to create two pieces one solely defines 4 points 
and a cell with no attributes, hence forming geometry only. And the second 
piece defines only points with point attributes.

However, it seems I am doing something(s) wrong since paraview reader does not 
recognize the information. It would be great if somebody tells me what I am 
doing wrong. Afterwards I can take it off by myself I guess.

Thanks a bunch!

Ersan
