Hi Richard,

Thank you for your feedback. While we are hoping that Paraview developers 
resolve this problem and accomplish a usable Tecplot reader, I may rewrite a 
code to output my data as legacy .vtk ASCII files.

May I ask you a question? it is probably simple: how to convert a legacy .vtk 
ASCII file to a binary file. Tecplot provides such a command line tool, 
preplot, which compresses data greatly before loading into Tecplot, otherwise 
uncompressed data could eat up all the memory quickly. For my own large scale 
simulation of particles, one snapshot generates as much as 14GB data for 
Tecplot, and preplot shrinks them to 2GB! I will run Paraview in parallel 
processing mode, but it is always optimal to compress ASCII data into binary 
before loading them into Paraview.

Thanks,
Beichuan Yan

Hello.

Sorry, I made a mistake in my previous mail: I see in the Tecplot reader help 
that it should be able to read unstructured:

 The output of the reader is a vtkMultiBlockDataset, of which each block is 
either a vtkStructuredGrid or a vtkUnstructuredGrid.


But I never succeeded in reading my own Tecplot unstructured grids with 
triangle elements, so I can't help you for this type of file.

Also, I had some problems in reading some structured grids because some Tecplot 
options in the ZONE card are not recognized by the reader, and I had to 
suppress it. The Tecplot reader should still be improved.

But if you try again Tecplot files with Structured or Unstructure grids, don't 
forget the two header lines for title and variables.

Richard.
