Hello- I'm getting a weird bug from PETSc. In my code I'm needing to add a vector, I call it u_rhs, to the system's rhs, u_system.rhs.
u_rhs is of type AutoPtr<NumericVector<Number> > and I'm trying to add them using the call u_system.rhs->add(*u_rhs.get()); I'm getting the following error: [0]PETSC ERROR: [1]PETSC ERROR: --------------------- Error Message ------------------------------------ [1]PETSC ERROR: --------------------- Error Message ------------------------------------ Arguments must have same communicators! [1]PETSC ERROR: Different communicators in the two objects: Argument # 3 and 1! Have any of you guys seen this before? I tried stepping through with a debugger to see what the communicators were, but, I couldn't figure out how to see that from the PETSc code, and I don't have a debug MPI built. Is libMesh creating special communicators? Any thoughts? Note: the code works fine in serial but dies when run in parallel. Thanks!
