o To reproduce the run : |
|
|
|
|
|
The genmake options are in .genmakerc, so that the simplest form |
|
|
of genmake can be used : |
|
|
cd input |
|
|
../../../tools/genmake |
|
|
make depend |
|
|
make |

The local copy of S/R aim_surf_bc.F (in code directory) provide |
| 9 |
|
a) the SST field (hard coded). |
| 10 |
|
b) the time in the year is fixed and corresponds to the spring equinox; |
| 11 |
|
this ensures a symetric forcing between N & S hemispheres. |
| 12 |
|
The model uses the standard 5-level vertical resolution of the Speedy_v23 |
| 13 |
|
code; the horizontal resolution is 2.8125 with 128x23 grid points. |

Configure and compile the code: |
| 18 |
|
cd build |
| 19 |
|
../../../tools/genmake2 -mods ../code [-of my_platform_optionFile] |
| 20 |
|
make depend |
| 21 |
|
make |
| 22 |
|
cd .. |
| 23 |
|
|
| 24 |
|
To run: |
| 25 |
|
cd run |
| 26 |
|
ln -s ../input/* . |
| 27 |
|
ln -s ../build/mitgcmuv . |
| 28 |
