The easiest way that I would suggest is to use the silo library. It
will handle
writing the hdf files for you.

It works very well with VisIT.

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
..

Dear Alexander,
Please see if the attached example C code helps. It is an example
from
HDF web site.
Best,
Ekin
