    6363=== TEST1: Validation of the SAS reference configuration 
    64 The reference configuration ORCA2_SAS_LIM has run sucessfully for 1 year using the set up defined in the NEMO shared reference.[[BR]] 
     64The reference configuration ORCA2_SAS_LIM has run sucessfully for 1 year using the set up defined in the NEMO shared reference (NEMO trunk rev  10272).[[BR]] 
     65It has been compared with a one year run of the forced reference configuration ORCA2_ICE_PISCES (NEMO trunk rev  10272).[[BR]] 
    6566Validation of the results: 
    66 * After one year experiment, the ice restart file is created and ''looks like a correct ice restart file'' 
     67* Some questions raised on the forced configuration itself, see below 
     68* After one year experiment, the ice restart file is created in the SAS run and ''looks like a correct ice restart file'' 
    6769* Having a complete an exact validation of this configuration will need some more work: here the ice is forced with an ocean input file containing the surface fields. These fields are not varying with time for now in the input file. To have a complete validation, it would need: 
    6870  * to run a one year of ORCA2_ICE_PISCES full reference configuration, with outputs of these daily surface fields 
     
    7072  * to make some subtle changes in SAS in order to have the exact same use of these fields in time (not the case for now, work done once by Sébastien and Eric, remaining to be taken in account again 
    7173  * Once all this is done, the ice restart file should be strictly identical between the ORCA2_ICE_PISCES run and the ORCA2_SAS_LIM one 
    72 This work has not been done at this stage, so that for now the conclusion is: the ORCA2_SAS_LIM configuration is running in NEMO 4.0, e.g. the SAS interface is functionnal in this case. 
     74This work has not been done at this stage, so that for now the conclusion is: [[BR]] 
     75'''The ORCA2_SAS_LIM configuration is running in NEMO 4.0, e.g. the SAS interface is functionnal in this case.'''[[BR]][[BR]] 
     76''Comments on forced reference configuration ORCA2_ICE_PISCES : [[BR]] 
     77The reference configuration is set up to start from rest (e.g. the very initial start, no ocean restart at all). In this case, using a call frequency of the ice =3 , nn_fsbc=3, is unstable: the run crashes after a few tenth of timesteps. Using nn_fsbc=5 (e.g. ice called every 5 timesteps, inducing less high frequencies in the forcing since the mean value used is calculated on a longer time scale), the model runs fine. This instabilities was not expected in the ORCA2 configuration, usually considered as very stable. Still this nn_fsbc=5 values has always been used up to now... ''
