#2397 closed Bug (fixed)

Restart failure of the ORCA2_ICE_PISCES reference configuration

Reported by: smueller Owned by: systeam

Severity: major Keywords: restart, ZDF
Cc: Branch review: failed
MP ready?: no Task progress: Unspecified

Description

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

     
    457457      sf_iwm(jp_dsc)%fnow(:,:,1) = 100. 
    458458 
    459459      !                             ! read necessary fields 
    460       CALL fld_read( 1, 1, sf_iwm ) 
     460      CALL fld_read( nit000, 1, sf_iwm ) 
    461461 
    462462      ebot_iwm(:,:) = sf_iwm(1)%fnow(:,:,1) * ssmask(:,:) ! energy flux for high-mode wave breaking [W/m2] 
    463463      epyc_iwm(:,:) = sf_iwm(2)%fnow(:,:,1) * ssmask(:,:) ! energy flux for pynocline-intensified wave breaking [W/m2] 

to reestablish a successful restartability test of reference configuration ORCA2_ICE_PISCES.
