default paths are (as used in testreport): |
| 5 |
|
set build_dir = ${cwd}/build |
| 6 |
|
set run_dir = ${cwd}/run |
| 7 |
|
set ROOT = ${cwd}/../../ |

Configure and compile the code: |
| 10 |
|
cd ${build_dir} |
| 11 |
|
${ROOT}/tools/genmake2 -mods ../code |
| 12 |
|
make depend |
| 13 |
|
make |
| 14 |
|
|
| 15 |
|
To run: |
| 16 |
|
cd ${run_dir} |
| 17 |
|
cp ../input/* . |
| 18 |
|
${build_dir}/mitgcmuv |
| 19 |
|
|

|
There is comparison output in the directory: |
| 21 |
|
results ( absolute path: ${run_dir}/../results ) |

This experiment is a channel with topography and four open |
| 27 |
|
boundaries. Salinity is not dynamically active in this experiment |
| 28 |
|
(linear equation of state with sBeta=0). Different kinds of open |
| 29 |
|
boundary values are used: zonal (x-)velocity U is prescribed at all |
| 30 |
|
open boundaries with values that are read from data files (specified |
| 31 |
|
in data.obcs); meridional (y-)velocity V is set to zero on all |
| 32 |
|
boundaries, and temperature to tRef(z), both in obcs_calc.F, this is |
| 33 |
|
the default behavior; at the western boundary, salinity values are |
| 34 |
|
used for salinity and one passive tracer in the same way. Salinity is |
| 35 |
|
set to sLev at all other boundaries, while a (nearly) homogeneous |
| 36 |
|
v.Neumann condition is applied to the passive tracer (the latter is |
| 37 |
|
the default in obcs_calc.F), with a relaxation (using pkg rbcs) in |
| 38 |
|
the Eastern part of the channel. Open boundary parameters are set in |
| 39 |
|
data.obcs. |
