5.2 Changing Algorithms

The main pitfall in doing this is to be aware of what the coupler and the other CCSM components expect from the ice model. Any changes that effect the coupler exchange, in terms of definitions of fields or even adding/subtracting fields is not recommended. It is best to leave alone the coupler exchange fields when modifying algorithms unless it is crucial for the new algorithm. This would then requre major modifications to the coupler and/or other components, all of which is beyond the scope of this document.
