[Paraview] Asking for Tecplot reader improvements and a sample Tecplot file for Unstructured Grids

[Richard GRENON]

Hello,

The Tecplot reader is very usefull, but it should be further improved 
because many Tecplot files (written by the user according to Tecplot 
format specifications or written by Tecplot itself !) still cannot be read !

I am usually using Structured grid, and the Tecplot reader works fine 
for most of my ASCII files, except for those that are written by Tecplot 
itself and that contain the STRANDID and SOLUTIONTIME tokens that are 
currently unsupported. I have to remove these unsupported tokens from 
all ZONE headers before reading with Paraview. May I suggest to ignore 
those unsupported tokens with just a warning rather than stopping reading ?

Another problem is with Unstructured grids. Reading the mail of Beichuan 
Yan (subject =Paraview 3.14.1 Tecplot Reader Errors ), I tried to read 
several ASCII Tecplot files with unstructured grids. Some of my files 
made Paraview freeze, other could not be read and gave many error 
messages such as :

"The record type XXX found in the file is unknown"

where xxx may be some coordinate data or something else.

It seems that the reader is bad positioned in the file because one or 
more token in the "ZONE" header are not recognized.

Looking at the reader source file, I tried to modify the header of 
simple Tecplot files with TRIANGLE or QUADRILATERAL elements, but I 
never succeeded in identifying which token is not recognized.

So, at that time, is the Tecplot reader really able to read unstructured 
grids or not ? If yes, could someone provide a sample Tecplot file for 
unstructured grid that Paraview can read ? This would help identifying 
what is not well recognized in the true Tecplot format.

Thank you in advance for your help.
