Hi,

I ran a case with pimpleDyMFoam in parallel and I have receive this error:

Code:
[11] #0  [12] [13] #0  [14] #0  [15] #0  [16] #0  [17] #0  [18] #0  Foam::error::printStack(Foam::Ostream&)[1] #0  [19] #0  [3] #0  Foam::error::printStack(Foam::Ostream&)[5] #0  Foam::error::printStack(Foam::Ostream&)[7] #0  Foam::error::printStack(Foam::Ostream&)[8] #0  Foam::error::printStack(Foam::Ostream&)[9] #0  Foam::error::printStack(Foam::Ostream&)[10] #0  Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)Foam::error::printStack(Foam::Ostream&)#0  Foam::error::printStack(Foam::Ostream&)--------------------------------------------------------------------------
An MPI process has executed an operation involving a call to the
"fork()" system call to create a child process.  Open MPI is currently
operating in a condition that could result in memory corruption or
other system errors; your MPI job may hang, crash, or produce silent
data corruption.  The use of fork() (or system() or other calls that
create child processes) is strongly discouraged.

The process that invoked fork was:

  Local host:          cfdnode12 (PID 23855)
  MPI_COMM_WORLD rank: 7

If you are *absolutely sure* that your application will successfully
and correctly survive a call to fork(), you may disable this warning
by setting the mpi_warn_on_fork MCA parameter to 0.
Someone know what does it mean?

Thanks in advance
