Hi,<br>
<br>
I am trying to make use of the more advanced features of the hdf5 viewer.<br>
<br>
I get the following error when running src/vec/vec/examples/tutorials/ex19.c:<br>
[0]PETSC ERROR: VecLoad_HDF5() line 251 in /opt/HPC/petsc-dev/src/vec/vec/utils/vecio.c Block size 1 specified for vector does not match blocksize in file 2<br>
<br>
Upon further investigating, I noticed that if Vec x2 is obtained by duplicating x1, then setting the block size for x2 also sets it for x1. Is this really the desired behavior?<br>
<br>
I am attaching an trivial example.<br>
