[Libmesh-users] exodusII write fails for example #9

[Carlos L. <rco...@gm...>]

Hello,

I've modified example #9 to do 1 time step and write the solution to
an exodus file by changing the line

GMVIO(mesh).write_equation_systems (file_name.str(), equation_systems);


to

ExodusII_IO(mesh).write_equation_systems ("out.e", equation_systems);

the program throws the following error:


[ex_put_block] Error: element block id 0 already exists in file id 8
    exerrval = -1
Error writing element block.
[0] src/mesh/exodusII_io_helper.C, line 118, compiled Apr 12 2009 at 14:16:59
terminate called after throwing an instance of 'libMesh::LogicError'
  what():  Error in libMesh internal logic

Are there other steps required for writing exodus files?

Thanks for your help,
Carlos.
