#2689 fixed latest Fmake_WORK.sh changes assume ln understands the -r option acc acc
Description

Context

Recent improvements to correctly enable the specification and use of alternative MY_SRC directories may break on some systems.

Analysis

The cause is the use of ln -r to create links relative to the current directory. This option is not understood by all versions of ln.

Recommendation

It will be more robust to be set the links explicitly. This works:

  • Fmake_WORK.sh

     
    8282      ln -sf ${ZDIR}/*.[Ffh]90 ${ZCONF}/WORK/. 
    8383      echo ${ZDIR}' content is linked to '${ZCONF}/WORK 
    8484    elif [ -d ${ZCONF}/${ZDIR} ] ; then 
    85       ln -rsf ${ZCONF}/${ZDIR}/*.[Ffh]90 ${ZCONF}/WORK/. 
    86       echo ${ZDIR}' content is linked to '${ZCONF}/WORK 
     85        for ff in ${ZCONF}/${ZDIR}/*.[Ffh]90 
     86        do 
     87         f=`basename $ff` 
     88         ln -sf ../${ZDIR}/$f ${ZCONF}/WORK/. 
     89        done 
     90      echo ${ZCONF}/${ZDIR}' content is linked to '${ZCONF}/WORK 
    8791    else 
    88       ln -rsf ${ZCONF}/MY_SRC/*.[Ffh]90 ${ZCONF}/WORK/. 
    89       echo 'External directory for MY_SRC does not exist. Using default.' 
    90       echo 'MY_SRC content is linked to '${ZCONF}/WORK 
     92        for ff in ${ZCONF}/MY_SRC/*.[Ffh]90 
     93        do 
     94         f=`basename $ff` 
     95         ln -sf ../MY_SRC/$f ${ZCONF}/WORK/. 
     96        done 
     97      echo 'External directory for MY_SRC unspecified or does not exist. Using default.' 
     98      echo ${ZCONF}/MY_SRC' content is linked to '${ZCONF}/WORK 
    9199    fi 
    92100done 

and will be submitted later if no one has a better idea.

#2688 fixed restartability issue with ISF at NEMO 4.0.x davestorkey davestorkey
Description

Context

My eORCA025 configuration at NEMO 4.0.4 fails restartability and I have traced this to the following lines in sbc_isf_init:

         !! compute first level of the top boundary layer
         DO ji = 1, jpi
            DO jj = 1, jpj
                ik = 2
!!gm potential bug: use gdepw_0 not _n
                DO WHILE ( ik <= mbkt(ji,jj) .AND. gdepw_n(ji,jj,ik) < rzisf_tbl(ji,jj) ) ;  ik = ik + 1 ;  END DO
                misfkt(ji,jj) = ik-1
            END DO
         END DO

(This applies to the parametrised option with closed cavities). For one particular ice shelf the initialisation of misfkt is changed after a restart, thus changing the results. If I follow Gurvan's suggestion in the comment and use gdepw_0 instead of gdepw_n, it fixes the problem.

Analysis

...

Recommendation

I see that the equivalent code in the trunk uses gdepw_0, so I propose to make this change in 4.0_HEAD as well. (But I would like to understand the initialisation of gdepw_n a bit better to see exactly what is going wrong - isn't this potentially a problem for other bits of the code??).

#2687 fixed nesting tools - interpolation of 2D-3D variables systeam clem
Description

The nesting tools for version 4.0-HEAD is not able to interpolate data with dimensions: (x,y) (x,y,z) It needs a time_counter dimension. It is constraining.

Recommendation

Eventhough this version is outdated, it is still used for 4.0 nemo versions, so I think we should release this constrain on time_counter. I coded it, so ready to be committed. If time is a dimension in the input file, it needs to be the unlimited dimension though.
