Yes write_mesh is implemented to work only in serial. It internally<br>
just calls write_file but with NULL options [1]. I believe write_mesh<br>
exists typically for debug purposes where we can dump the partial mesh<br>
from each process and analyze it. I don't see why this should be<br>
restricted this way and can certainly change that. Alternately, you<br>
can and should directly call write_file (which can store tags and<br>
other set data too) with options="PARALLEL=WRITE_PART;".<br>
<br>
Iulian, we should update the documentation to say that write_mesh only<br>
works in serial. Or optionally allow user to specify options so that<br>
both serial/parallel writes can be enabled. Also, the documentation<br>
for load_file and write_file should describe what typical options can<br>
be used to read/write in parallel.<br>
