Restart failure of the ORCA2_ICE_PISCES reference configuration

[smueller]

Context

The restarted run carried out as part of the SETTE restartability test of the ORCA2_ICE_PISCES reference configuration crashes.

Analysis

The model crash occurs following the call of subroutine fld_read in subroutine zdf_iwm_init (source:/NEMO/trunk/src/OCE/ZDF/zdfiwm.F90#L460​). In this call of fld_read, the first argument identifies the time step index as 1 instead of nit000, which, in model runs with nit000 > 1, results in the omission of initialisation steps during the fld_read call made by subroutine zdf_iwm_init.

Fix

source:/NEMO/src/OCE/ZDF/zdfiwm.F90 could be adjusted according to

src/OCE/ZDF/zdfiwm.F90
