Alexander,
an option might be to use the F5 library (F5.origo.ethz.ch) which was
designed to work with Cactus/Carpet AMR mesh refinement and to use the
XDMF extractor tool which extracts the F5 metadata as XML. We used that
a couple of years ago to get F5-data into Paraview, I would assume it
would be similar with Visit. Let me know if you're interested in that,
I'd need to contact the developer of that XDMF extractor tool as I don't
have it myself at the moment, but it would be a good occasion to revive
this tool.
Werner
BTW.: F5 is storing time-dependent 3D data as a series of 3D instances,
not as a 4D field, such that the data structures may vary over time,
which is the case for AMR data usually.

I am afraid I have not described what I want to have clear enough....
I have a 3-d not always regular mesh (we are working with mesh
refinement). On
this mesh I have several variables, and again for each variable several
time
steps. To make plots of these variable, and also to create time series
plots I
would like to use VisIt, which uses XDMF as a reader for HDF5 data.
In order to get the plots of VisIt correct, the HDF5 datasets must be
populated as follows:
1) x coordinates
2) y coordinates
3) z coordinates
(all the coordinates as 3-d arrays)
and finally 4) the data.
How can I add seveals time steps of these data? Must I always add the
coordinates in advance or not? Have I a possiblity to mark the time step?
The example given by Ekin only shows how to add one 3-d field, nothing
about
coordinates and about time steps. I hope my problem is more clear now ..
Best wishes
Alexander
Dear Alexander,
Please see if the attached example C code helps. It is an example from
HDF web site.
Best,
Ekin
