#2522 fixed sbcflx defects systeam clem
Description

Context

The flux formulation (sbcflx) has several defects:

1) The fields that are read are not masked which may end up in a model crash if the filled values on the continents are not set to zero

2) It seems (to be verified) that all the fields need a lbc_lnk otherwise the north fold is not ok. I do not understand why. This observation comes from a simulation using nemo3.6, so it may not apply to 4.0 and the trunk

3) To fully use sbcflx, one needs to read the salt flux (sfx) from the namelist and not impose it to 0

Analysis

Recommendation

Correct the above points for 4.0 and the trunk.

#2521 fixed potentially test undefined values in stpctl and other places... smasson smasson
Description

Context

At least when nn_hls > 1 and in some configurations (at least SAS), stpctl is stoping the model for non-existing errors… so good… :-(

Analysis

in stpctl mpp_min/max and mpp_min/max_loc are done over the whole domain instead of using only the inner domain. In consequence, they sometimes pick-up values (randomly) from non-initialized parts of the halos.

Fix

Make sure that we use only the inner domain when using mpp_min/max and mpp_min/max_loc in stpctl.

Check also the other routines using these functions…

cherry on the cake: modify mpp_min/max_loc so:

  • it works even without key_mpp_mpi
  • by default, it sents back global domain indices without halos so the information matches input/outputs files and does not depend on nn_hls value.
#2520 fixed Invalid Memory Access in tra_adv_cen systeam francesca
Description

Context

There is a memory access error in traadv_cen.F90 file (line 129) of the r4.0-HEAD NEMO version. It happens since the ji index of DO loop starts from 1 and the value of ztu at the line 133 is read at the position ji-1. I think that ji should start from 2..

Moreover, probably a communication on zwx and zwy should be added after the loop.

Analysis

Fix
