[Paraview] Reading ASCII Tecplot data

[DParker at chromalloy.com]

I've had no issues reading ASCII TECPLOT files into Paraview. We modified 
our CFD code to generate ASCII TECPLOT files for post-processing in 
Paraview because we were having issues reading binary PLOT3D files with 
Paraview. The ASCII files are very large and slow to read though. Also we 
don't yet have a good solution for generating derived variables from the 
raw data - we're using a Python script to generate a series of Calculator 
filters. 

I suggest reviewing the TECPLOT Data Format Guide (
ftp://ftp.tecplot.com/pub/doc/tecplot/360/dataformat.pdf) for details on 
the ASCII file format. 

Our files look like this:
TITLE="TECPLOT Wall Output"
VARIABLES= "x" "y" "z" "density" "heat-flux" "wall-temp-out-surf" 
"absolute-pressure" "x-wall-shear" "y-wall-shear" "z-wall-shear" "y-plus"
ZONE T="airfoil", i=362, j=69, k=1, DATAPACKING=BLOCK
  2.42144130E-02  2.40880810E-02  2.39595771E-02  2.38230173E-02 
2.36812476E-02  2.35372968E-02  2.33908389E-02  2.32443120E-02 
2.30974443E-02  2.29516029E-02  2.28067115E-02  2.26650704E-02 
2.25249752E-02  2.23834831E-02 ...

Each "surface" is indicated by a ZONE header with the zone title, i/j/k 
counts, and DATAPACKING flag.

Hi everyone,

What is the current status of Paraview's ability to read in Tecplot data?  
I've had mixed success reading in ASCII (usually *.DAT) files.  For 
example, many of the DAT files listed here 
http://people.sc.fsu.edu/~jburkardt/data/tec/tec.html cannot be read in to 
Paraview (3.8.0 64-bit, running on Ubuntu 10.10).

I'm pondering whether its worth writing a script to convert my DAT files 
to VTU instead...

cheers,
Novak._______________________________________________
