Libmesh has been distributing and running with the new ExodusII library for
over a month now and I haven't seen any issues on
the mailing list regarding the new version so I'm preparing the next patch in
this set.
IMPORTANT:
This change could potentially break users doing regression testing with the
Exodus output format as the output meshes will
contain a block, sideset and nodeset with an id of zero (previously these
entities were all set to 255), which may differ with a
mesh differencing tool. On the plus side this will make the Exodus output more
consistent with the other output formats in
Libmesh and will allow us to move forward with increasing the size of
subdomain_id without further effecting Exodus output.
Let me know if there is any reason not to commit this patch, otherwise I'll get
it applied in the next day or two.
That breakage is important to warn about, but not important enough to
delay or change the patch. Worst case workaround: maybe svn add a
fix_old_exodus script that reads in oldfile, changes any ids from 255
to 0, and then writes fixed_oldfile?
