            1 Ross ice shelf model (diagnostic validation mode)
            2 =================
            3 
            4 This example is documented in subsection 12.2 of the PISM User's Manual as an
            5 example of using observed velocities to validate PISM's model for the flow in
            6 ice shelves.
            7 
            8 This example is a regional model of an ice shelf using observed, fixed geometry
            9 and observed velocities as boundary conditions.  PISM does a `-y 0` (zero
           10 duration) diagostic run; see subsection 5.5 of the User's Manual.  A python plot
           11 script can compare observed and numerical velocities in the interior of the ice
           12 shelf once the run completes.
           13 
           14 To do the example, run `preprocess.py` in the parent directory, and then do the
           15 following in the current directory:
           16 
           17     $ ./run_diag.sh 2 211 0.6
           18 
           19 At this resolution the run takes only a few seconds.  To compare to
           20 observations, and generate figures like those in the User's Manual, do
           21 
           22     $ ../plot.py diag_Mx211.nc
           23 
           24 Note `run_diag.sh` accepts three arguments: `run_diag.sh N Mx E` does a run with
           25 `N` MPI processes, a `Mx`x`Mx` grid, and option `-ssa_e E`.
