[Paraview] Reading ASCII Tecplot data

[Adriano Gagliardi]

This is the code from the TecplotReader that handles the data connectivity
information:
 
while (  !( tok != "T"  &&
              tok != "I"  &&
              tok != "J"  &&
              tok != "K"  &&
              tok != "N"  &&
              tok != "Nodes" &&
              tok != "E"  &&
              tok != "Elements" &&
              tok != "ET" &&
              tok != "ZONETYPE" &&
              tok != "F"  &&
              tok != "D"  &&
              tok != "DT" &&
              tok != "DATAPACKING"  &&
              tok != "VARLOCATION" )
 
These are your options for the header. Good luck!

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>
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/%7Ejburkardt/data/tec/tec.html>
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._______________________________________________
