Hi, Folks --
I am trying to get libMesh to output to an Exodus II file. I am using a
recent pull of the SVN version of libMesh so that I can use libMesh with
PETSc 3.0.0.
(By the way, I don't really care whether it is Exodus II or not --- I am
just trying to output data in a format which can be read by the VisIt
visualization tool.)
I tried modifying ex3.C to change the I/O from GMV to ExodusII, i.e., I
simply changed the I/O from:
// After solving the system write the solution
// to a GMV-formatted plot file.
GMVIO (mesh).write_equation_systems ("out.gmv", equation_systems);
to:
// After solving the system write the solution
// to a Exodus II-formatted plot file.
ExodusII_IO (mesh).write("out.exd");
This compiles fine but I get the following error at run time:
[ex_put_block] Error: element block id 0 already exists in file id 13
exerrval = -1
Error writing element block.

I get similar errors if I try to do similar things in ex4.
What do I need to do to output to this format?
Thanks,
