wrong heat budget of the leads in LIM3

Description (last modified by nicolasmartin)

This ticket applies to the trunk and different development branches (i.e. dev_v3_6_STABLE_r6506_AGRIF_LIM3 ; dev_r8183_ICEMODEL ; dev_r8127_AGRIF_LIM3_GHOST)

There is a bug concerning the heat budget of the leads in case of melting in the sea ice model.
Heat is considered to be equal to 0 anytime because of this line:

IF( .NOT. ln_limdH )  fhtur (:,:) = 0._wp ; fhld  (:,:) = 0._wp

The correct line is:

IF( .NOT. ln_limdH ) THEN 
   fhtur (:,:) = 0._wp
   fhld  (:,:) = 0._wp

Consequence is certainly that there is not enough melting in the MIZ

The effect of the bug is that the heat input in the lead is used to warm the ocean, instead of to melt the ice from below.

Thus, the bug implies that the ice melt is delayed (and reduced), but the heat is actually not lost.
