                0006 Configure and compile the code:
                0007   cd build
                0008   ../../../tools/genmake2 -mods ../code [-of my_platform_optionFile]
                0009   make depend
                0010   make
d6a28d3589 Jean*0011   cd ..
a4db914080 Jean*0012
                0013 To run:
d6a28d3589 Jean*0014   cd run
a4db914080 Jean*0015   ln -s ../input/* .
d6a28d3589 Jean*0016   ln -s ../build/mitgcmuv .
a4db914080 Jean*0017   ./mitgcmuv > output.txt
d6a28d3589 Jean*0018   cd ..
a4db914080 Jean*0019
                0020 There is comparison output in the directory:

                0023 Comments:
d6a28d3589 Jean*0024 o the set up is similar to that of tutorial_global_oce_latlon
a4db914080 Jean*0025 o the code directory contains calc_phi_hyd.F, where the potential is computed
                0026   according to the more natural finite volume discretization. Finite difference
                0027   discretization is energy conserving, but the representation of the "fixed"
                0028   surface (interface ocean-atmosphere) is less consistent.
                0029 o the code directory also contains dynamics.F which calls
                0030   remove_mean_rl.F, a generic routine, to remove the mean from the
                0031   diagnostic variable phiHydLow (sea surface height/gravity in pressure
d6a28d3589 Jean*0032   coordinates)

                0034 changes: 07 Feb. 2003 (jmc):
                0035 o find difficult to maintain the local version of dynamics.F up to date.
                0036   therefore, has been remove from the code directory.
d6a28d3589 Jean*0037   One can recover the same version (but up to date) simply
a4db914080 Jean*0038   by activating the commented lines [between lines Cml( and Cml) ],
                0039   at the end of the standard version of dynamics.F
                0040 o finite volume form of calc_phi_hyd.F is now a standard option.
                0041   only needs to set integr_GeoPot=1 in file "data" to select this form.
