S&E boundaries are held constant (i.e. # # not updated). At first time step, waves are eliminated inside the domain # # by an ice field. So at this time, SWH is 1 m at S and E boundaries, but # # zero in the interior. After that time, it is a case of swell propagating # # from SE to NW. Mud is defined in the NW quadr. The interior of the swell # # field is uniform until it enounters the mud, which happens around hr 9. # # The swells are dissipated over the mud patch (NW quadrant). By hour 24, # # the results are almost stationary: uniform SWH outside the mud field and # # gradual damping (from SE to NW) over the mud field. Note: ice is used # # in this case simply as a mechanism to eliminate wave energy at the first # # time step and this test case is not concerned with the physics of waves # # through ice. # # # # Reference (w/plots): Rogers and Orzech, NRL Memorandum Report (2013) # # available from http://www7320.nrlssc.navy.mil/pubs.php # # # # Example run_test commands: # # (some details will vary by local system and configuration) # # ./bin/run_test -n 3 -p mpirun -s BT8_MPI -w BT8_MPI ../model ww3_tbt2.1 # # ./bin/run_test -n 3 -p mpirun -s BT9_MPI -w BT9_MPI ../model ww3_tbt2.1 # # ./bin/run_test -s BT8 -w BT8_SER ../model ww3_tbt2.1 # # ./bin/run_test -s BT9 -w BT9_SER ../model ww3_tbt2.1 # # On a workstation of 2010 vintage, the run-times for the above 4 test # # cases are as follows: 18 s, 11 s, 38 s, 23 s # # # # origination: Erick Rogers, Oct 2012 # # last updated: Erick Rogers, Nov 2013 # # # # Copyright 2009 National Weather Service (NWS), # # National Oceanic and Atmospheric Administration.
