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/ IO/vtkMultiBlockPLOT3DReader.cxx, line 783

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

Sincerely,
Rick
