Berk:
I really appreciate your response, but it is still not working for us.
We produce 64-bit OVERFLOW grid and q files and are trying to visualize
them using ParaView 4.0.1. The grid files are read without any problem.
However any attempt to read the q files produces errors.
On Windows 32-bit:
ERROR: In
C:\DBD\pvs-x32\paraview\src\paraview\VTK\Common\ExecutionModel\vtkExecutive.cxx,
line 754
vtkPVCompositeDataPipeline (1E30E8E8): Algorithm

This error occurs immediately after selecting the q file.
If we then persist and hit the "Apply" button, the following error
message pops up:
ERROR: In
C:\DBD\pvs-x32\paraview\src\paraview\VTK\Common\ExecutionModel\vtkExecutive.cxx,

We get the same type results on Linux 64-bit systems.
Any recommendations would be appreciated! Thanks!!

Subject: Re: [Paraview] NASA OVERFLOW reader
The Plot3D reader in 4.0 can read 32 bit and 64 bit Overflow files. Here are
the messages I sent to the Overflow mailing list a while ago:
Hi folks,
I am happy to report that there is now a robust Plot3D / Overflow reader in
ParaView that does automatic format detection for binary files. I am sorry that
it took this long. It was not the easiest reader to write. It works with:
- Overflow files (any number of Q variables)
- Single and double precision real values
- C and Fortran output
- Big and little endian files
- ASCII and binary files
- Q file series for unsteady flows
I also developed a simple meta file format that supports xyz file series as
well as actual time values for each Q file (which is currently not supported
without the meta file - this is needed for accurate particle advection). I am
going to provide some documentation about this in the ParaView Wiki soon.
You can test this out by downloading the development binaries:
Mac:
http://open.cdash.org/viewFiles.php?buildid=2873933
Linux:
http://open.cdash.org/viewFiles.php?buildid=2873792
Windows:
http://open.cdash.org/viewFiles.php?buildid=2873742
Please give it a try and let me know if you run into issues. If you would like
to wait for a stable release, ParaView 4.0 is scheduled to be released early in
May.
---------------------------------
I am happy to announce that ParaView now supports function files. There is now
support for pretty much the entire original Plot3D spec as well as Overflow.
Some of the new features are:
- Overflow files (any number of Q variables)
- Function files (any number of functions)
- Single and double precision real values
- C and Fortran output
- Big and little endian files
- ASCII and binary files
- XYZ and/or Q file series for unsteady flows and changing geometry
- More robust iblank support
XYZ file series require the use of a meta-file (p3d extension) as described
here:

Best,

Is there a generally available reader for NASA's OVERFLOW CFD code?
A plugin perhaps?
