'''Author''' : Clement Bricaud
'''ticket''' : #1455

'''Branch''' : [​svn+ssh://cbricaud@forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/branches/2015/dev_5974_MERCATOR10_LIMINI] 
----

=== Description ===
enable sea ice initialization wtih a netcdf file in LIM3

----
=== Testing ===
Testing could consider (where appropriate) other configurations in addition to NVTK].

||NVTK Tested||!'''YES'''||
||Other model configurations||!'''CREG025, CREG12, ORCA025, ORCA12'''||
||Processor configurations tested||  25*40, ....||
||If adding new functionality please confirm that the [[BR]]New code doesn't change results when it is switched off [[BR]]and !''works!'' when switched on||!'''YES!'''||

(Answering UNSURE is likely to generate further questions from reviewers.)

The solution of ORCA2_LIM3 on this branch has been compared to the trunk revision 5974 and results are the same


=== Bit Comparability ===
||Does this change preserve answers in your tested standard configurations (to the last bit) ?||!'''YES !'''||
||Does this change bit compare across various processor configurations. (1xM, Nx1 and MxN are recommended)||!'''NO!'''||
||Is this change expected to preserve answers in all possible model configurations?||!'''YES!'''||
||Is this change expected to preserve all diagnostics? [[BR]]!,,!''Preserving answers in model runs does not necessarily imply preserved diagnostics. !''||!'''YES!'''||

If you answered !'''NO!''' to any of the above, please provide further details:

 * Which routine(s) are causing the difference?
 * Why the changes are not protected by a logical switch or new section-version
 * What is needed to achieve regression with the previous model release (e.g. a regression branch, hand-edits etc). If this is not possible, explain why not.
 * What do you expect to see occur in the test harness jobs?
 * Which diagnostics have you altered and why have they changed?Please add details here........

----
=== System Changes ===
||Does your change alter namelists?||!'''YES!'''||
||Does your change require a change in compiler options?||!'''NO !'''||

If any of these apply, please document the changes required here.......
SHARED/namelist_ice_lim3_ref iceini bloc is modified ( add fldread structure for netcdf input file )

----
=== Resources ===
when we don't read netcdfile, the distribution algorithm will cost a little bit more, due to the fact that it has been rewritten on 2D dimension, to be compatible with reading netcdfile option.

----
=== IPR issues ===
||Has the code been wholly (100%) produced by NEMO developers staff working exclusively on NEMO?||!'''YES!'''||

If No:

 * Identify the collaboration agreement details
 * Ensure the code routine header is in accordance with the agreement, (Copyright/Redistribution etc).Add further details here if required..........
