Hi again,

I am now trying to write a vector to an HDF5, this time using a DM
structure to impose the vector layout.

Creating the vector with (as in src/dm/examples/tutorials/ex10.c)


every works fine, i.e. the hdf5 file has the correct layout given by the
dimension of the DM. On the other side, if I use:


the hdf5 file contains a single dimension vector, apparently negecting the
VecSetDM instruction (I would need this for vectors created by
MatCreateVecs, in order to have both right and left vectors available).

I did some testing but I did not manage to solve this. Is there anything I
am doing wrong, or is this the way it is supposer to work?

Thanks as always for your help,
