[Paraview] paraview won't read plot3D files

[Rick Burnes]

Paraview appears to have a limited ability certain plot3D files that  
were likely generated from C/C++ code, but is unable to read plot3D  
files generated from Fortran code.  When I open a Fortran generated  
plot3D file I select "plot3D" as the file type and then select the  
following three options: "binary file", "has byte count" and if needed  
"multigrid".  I have tried various combinations of these options  
without success.  I wrote a short and simple Fortran program to  
generate a small test plot3D grid file and data file, which I can  
successfully read with tecplot, but is not readable in paraview  
3.6.1.  Has anyone had success reading Fortran generated plot3D files  
with a recent version of paraview and if so, what plot3D format was  
used and what paraview file options were selected?

This is for paraview 3.6.1 on a mac running leopard.  However, I run  
into the same problem on the windows version of paraview as well.

Here is the error message I receive:

ERROR: In /Users/kitware/ParaViewReleases/ParaView-3.6/ParaView3/VTK/

Also, are there any plans to improve paraview's ability to read plot3D  
files?
