2Purpose
3-------
4This demonstration case can be used to study the advection of a patch of ice in a bi-periodic channel
5with a slab ocean (i.e. 1 ocean layer) and an agrif zoom in the center

8Experiments
9-----------
10Two experiments can be configured:
11
12a) A simple channel at 3km horizontal resolution (slightly variable => +- 10%)
13              ==> in MY_SRC/usrdef_hgr.F90, uncomment the part "variable scale factors" and comment part "constant scale factors"
14
15b) A simple channel at 3km horizontal resolution (constant scale factors)
16              ==> in MY_SRC/usrdef_hgr.F90, comment the part "variable scale factors" and uncomment part "constant scale factors"

19How to run
20----------
21
22a) Compile and run the model once to get a mesh_mask.nc file with the following command:
23../../../makenemo -r ICE_AGRIF -n ICE_AGRIF -m X64_ADA -j 4
24mpirun ./nemo -np 1
25
26b) Create the initial condition file for sea-ice (initice.nc) by running this python script:
27python ./make_INITICE.py
28
29c) Run the model a second time
30mpirun ./nemo -np 4

32---------------
33What to look at
34---------------
35the advection through an agrif zoom 1:3
36   for a square (ice concentration) or a gaussian (ice volume)
37      with either a constant velocity (ln_dynADV2D=T)
38               or a constant ice-atm. stress, thus velocity is calculated by rheology (ln_dynRHGADV=T)
39      with 1 or 5 ice categories (jpl=1 or 5)
40         (note that ln_dynADV2D=T only works with jpl=1)
