[Libmesh-users] parallel error

[蔡园武 <yua...@gm...>]

**
Hi, guys,
I tried to use parallel in my code, but got error. I traced my code and
found where the error is:
I defined vector using:
    NumericVector < Number > &U11 = system.add_vector("U11");
and init it:
    U11.init(system.n_dofs(), system.n_local_dofs());
After solve, I stored the solution in the vector:
    U11 = *system.solution;
Then, in the following, I want to use the solution value in the vector:
    a = U11(dof_indices[i]);
But I found that U11 only contains local dofs, when I want to access dofs
not stored in local, I got an error.
So where am I wrong?
Thank you for your help!

Error:

MPI_ABORT was invoked on rank 0 in communicator MPI COMMUNICATOR 3 DUP FROM 0

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
