This will never work for large datasets, no compression is possible, no
parallel IO, lots of extra space required.

You are on target to point out the issues that the one will face when a
high resolution 3D results are required, lots of large files are indeed
a challenge which should be anticipated for in the design of the CFD
code. However, judging from Emmanuel's initial mail, he is not asking
about design issues he will face when implementing a CFD code, he is
rather asking how he can get a run up on the screen. My impression is
that he just needs something simple to get him up and going. <br>
<br>
CFD code design consideration aside, assuming that his results are in
HDF5 format, if he can get a HDF5 to VTK converter up and running, then
down the road he can extend that into a PARAVIEW reader(thereby
bypassing the extra file io) if needed(like you have done), so that is
a win win. <br>
<br>
It sounded like he hadn't even installed HDF5 and H5Utils onto his
workstation, so that is probably the first order of bus. At least then
he can use the H5dump to see the contents of his files. Then install
VTK and/or Paraview. In any case it sounds as though he has some work
in front of him to get up and going...<br>

<pre wrap="">After installation of VTK for use with purely C++ on windows, I have
been struggling with how to get started with reading my CFD datasets
for visualization. I have done some research with HDF5 but having
problem with having to go into increasing number of third party
software and libraries. Recently, I learnt that H5utils can convert
HDF5 datasets into the formats required by other free visualization
software like VTK. But it’s only for UNIX systems, though it appears
help can come from CygWin .
Can anyone help? I just want to visualize simple 2D/3D grid-based
scalar and vector flow fields simulated with my native codes.
Thanks in anticipation
