[Paraview] paraview won't read plot3D files

[Rick Burnes]

Yes, I have also generated an ASCII plot3D file, which I can get  
paraview to read.  However, paraview does not correctly interpret the  
grid file.  The geometry I create with my simple Fortran code is a  
cube.  Paraview successfully reads both the ASCII grid and data files,  
but when I view it in paraview the geometry is incorrect.  Tecplot  
does not have this problem with the same grid and data files.  I am  
interested in any suggestions on the right combination of options to  
choose when reading this plot3D file into paraview, but I have not  
been able to find the correct combination of options to read a plot3D  
binary grid and data file.  In addition, since paraview does not  
display the correct geometry when I have it read an ASCII version of  
the same grid and data plot3D files I believe there is more to this  
than just choosing the right options.

There are a number of different plot3D formats and I have tried  
reading a number of these into paraview, all with the same results.

Sincerely,
Rick
