Tyson,
You won't get a common answer, but here is my $00.02. The EnSight format
has a nice feature that every variable has its own file. So, each
'sample point' will have its own file. The file names can be as you
want, numeric or alphabetic. The EnSight format has a geometry file, but
if you want to use single vertex cells it won't become very large. If
you want to be a little more graphical, you could use 64 4-node quads
with their respective coordinate positions. Additionally, you could add
a relatively coarse mesh of the structure. (ParaView has a Filter that
will take a point set (your 64 single-point cells) and construct a
triangular mesh to provide some geometry.
The EnSight format uses a meta-file (aka *.case file) that references
all of the files in the datum set, example attached. It will be some
work the first time around, but well worth it in my opinion.
(I use this file-format myself for million-element 3-D meshes for
transient dynamic simulations. I would not leave home without it.)

Hi,
I'm trying to help one of our users (HPC center) use ParaView to work
with their wind tunnel data. They have a large number of time samples
(60,000) from a series of surfaces with from a small number of sample
points (64).
The sample points are irregular but structured as they are laid out to
be more dense in areas that should see more differences (i.e., at best
you could say it was a non-uniform grid with several of the points not
used).
What file format should this data be put in to import into ParaView?
The VTK legacy formats and XML description formats seem painful to use
with this number of timesteps and I believe (please correct if wrong)
that the NetCDF wants a regular grid.
Thanks! -Tyson
