[Paraview] Tecplot reader from PV 3.8.1 fails on Linux Redhat CentOS

[Richard GRENON]

Hi Adriano.
I always used the downloaded 3.8.1 binaries from the Paraview download 
page. Following is the header of my ascii Tecplot File. I don't know 
exactly for which Tecplot version they are formatted by our CFD 
software, but they are readable by Tecplot 360, and I am using the same 
Tecplot files that I used on my HP workstation.

> TITLE = ""
> VARIABLES = "x" "y" "z" "frictionvectorx" "frictionvectory" 
> "frictionvectorz" "frictionmodulus" "yplusmeshsize"
> ZONE T="Window(s) : sf13257_blk_39",  I=17,  J=13, F=BLOCK
>  2.6397699E+01  2.6377867E+01  2.6358173E+01  2.6338665E+01  
> 2.6319424E+01  2.6300579E+01
This is a multiblock dataset and the file contains many Zones (one for 
each block). Note that the third dimension K is missing as each block is 
a surface grid. Tecplot 360 assumes that K=1, and the PV 3.8.1 Tecplot 
reader also does not care of the missing K dimension as it was working 
on HP Redhat 5. On Dell CentOS, no error message, but the data are 
incoherent.

Regards.

Richard
