[8962] | 2 | Purpose |
[8900] | 3 | ------- |
[10516] | 4 | This demonstration case can be used to study the advection of a patch of ice in a bi-periodic channel |
5 | with a slab ocean (i.e. 1 ocean layer) and an agrif zoom in the center | |

8 | Experiments | |
9 | ----------- | |
[8900] | 10 | Two experiments can be configured: |
[8962] | 11 | |
[8900] | 12 | a) A simple channel at 3km horizontal resolution (slightly variable => +- 10%) |
[10516] | 13 | ==> in MY_SRC/usrdef_hgr.F90, uncomment the part "variable scale factors" and comment part "constant scale factors" |
[8962] | 14 | |
[10516] | 15 | b) 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" | |

18 | ---------- | |
19 | How to run | |
20 | ---------- | |
21 | ||
[8962] | 22 | a) Compile and run the model once to get a mesh_mask.nc file with the following command: |
[10516] | 23 | ../../../makenemo -r ICE_AGRIF -n ICE_AGRIF -m X64_ADA -j 4 |
24 | mpirun ./nemo -np 1 | |
[8900] | 25 | |
[8962] | 26 | b) Create the initial condition file for sea-ice (initice.nc) by running this python script: |
[8900] | 27 | python ./make_INITICE.py |
28 | ||
[8962] | 29 | c) Run the model a second time |
[10516] | 30 | mpirun ./nemo -np 4 |
[8900] | 31 | |
32 | --------------- | |
33 | What to look at | |
34 | --------------- | |
[10516] | 35 | the advection through an agrif zoom 1:3 |
[8900] | 36 | for a square (ice concentration) or a gaussian (ice volume) |
[10554] | 37 | with either a constant velocity (ln_dynADV2D=T and define rn_uice & rn_vice) |
[8900] | 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) | |
[10516] | 40 | (note that ln_dynADV2D=T only works with jpl=1) |
