+Purpose

-The aim of this demonstration case is to study the advection of a patch of ice in a bi-periodic channel with a slab ocean (i.e. 1 ocean layer which does not interact with sea-ice).
+This demonstration case can serve to different purposes:
 
+1) The main one: study of the advection of a patch of ice in a bi-periodic channel with a slab ocean (i.e. 1 ocean layer)
+              ==> set ln_icethd=false in namelist_ice_cfg
+
+2) Secondary: study of ice thermodynamics in the same basin
+              ==> set ln_icedyn=false in namelist_ice_cfg
+              ==> eventually change usrdef_sbc.F90 in MY_SRC to fit your needs
+

+Experiments
+-----------
 Two experiments can be configured:
+
 a) A simple channel at 3km horizontal resolution (slightly variable => +- 10%)
+              ==> remove key_agrif in cpp keys
+
 b) Same as a) but with an Agrif zoom in the center 1:3, and 3 ghost cells (defined in par_oce.F90)
+              ==> add key_agrif in cpp keys
