#1690 closed Bug (wontfix)

unallocated array hit when using bdy + LIM2

Reported by: molines Owned by: vancop
Priority: low Milestone: Unscheduled
Component: BDY Version:
Severity: minor Keywords: LIM2,
Cc: vancop

Description (last modified by nicolasmartin)


  • nemo_3_6_STABLE : key_bdy, key_lim2
  • run time error :
    forrtl: severe (408): fort: (2): 
    Subscript #2 of the array FRLD has value 15 which
     is greater than the upper bound of -1  [ bdydta.f90 l 219 ] 


  • when using nn_ice_lim_dta = 0 [ debuging purpose ], in bdy_dta array frld(:,:) is used, but not already allocated.
  • In step.F90, the actual sequence is :
    108       IF( lk_bdy     )  THEN
    109          IF( ln_apr_dyn) CALL sbc_apr( kstp )   ! bdy_dta needs ssh_ib 
    110                          CALL bdy_dta ( kstp, time_offset=+1 )   ! update dynamic & tracer data at open boundaries
    111       ENDIF
    112                          CALL sbc    ( kstp )         ! Sea Boundary Condition (including sea-ice)
    113                                                       ! clem: moved here for bdy ice purpose
    114       !>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
  • Note Clem's comment ! : in fact, frld is allocated in first call to sbc (and other lim arrays too ).
    • in the actual step.F90 call to sbc is done after call to bdy_dta, hence the problem.


  • understand why this call was moved here by Clem ?
  • for LIM2, it works if the call to sbc is done before the call to bdy_dta

  • In fact the proposed fix only work when using initial data for the bdy_ice.
    • Moving sbc call before bdy_dta when using data in files produce an error, because a call to bdy_ice_lim is done, using unitialized data for frld, hicif and hsnif (with eventual random high values).
  • Therefore, the good fix will be (probably) to move allocation of lim2 array out of the sbc routine.
    • =⇒ still to be done !
