[Paraview] pvtr file format

[Felix Wolfheimer]

Hello!

I'm trying to use the .pvtr file format to visualize a vector field 
associated to a rectilinear grid. Unfortunately I get not the expected 
result. I have two .vtr files which are connected via a .pvtr file. I'm 
trying to visualize the datasets using only one instance of ParaView. 
Maybe this is a problem? It seems to me, that the data from the second 
vtr file is read and displayed incorrect. I will provide you a short 
example to reproduce the problem. The dataset consists of  a vectorfield 
distributed on two vtr files. The values in the first file contains a 
field pointing only in x-direction and the second file contains field 
values pointing only in y-direction.

Any suggestions would be greatly appreciated. Thanks in advance

Felix
