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

[Adriano Gagliardi]

Ah, ok. Well, I have no answer, although it seems very strange that the
binaries should perform so differently. I use CentOS 5.4 with an older
version of ParaView. If I get hold of the ParaView 3.8.1 binaries, I'll test
out the Tecplot multiblock reader myself and see how it goes.

Regards,

Adriano

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
