Message:

VMG: OMPI 2.1.1 has issues on writing files in parallel.

• for this reason, we deactivate the writing of the grid for open boundary conditions after computing boundary values via the greens function.
• FIX: CreateSerialOutputFile() returned pointer to scope-internal MPI_File.
• modified CreateParallelOutputFile() to use stringstreams for creating the filenames.
