I used the MPI_Cart_create command to create a 3D cartesian
decomposition in a CFD code. After completing my iterative solution, I
need to re-compose several arrays so I can output data for the entire
domain to a data file.  Should I define datatypes and gather the data,
or is there an easier way?  Many thanks to anyone who can help.
