This correction is called from dyn_spg_flt, but not from dyn_spg_ts. Hence, volume correction does not apply when using key_dynspg_ts. The following is in dynnxt.F90: {{{#!f # if defined key_bdy ! !* BDY open boundaries IF( lk_bdy .AND. lk_dynspg_exp ) CALL bdy_dyn( kt ) IF( lk_bdy .AND. lk_dynspg_ts ) CALL bdy_dyn( kt, dyn3d_only=.true. ) !!$ Do we need a call to bdy_vol here?? ! # endif }}} Adding something like {{{#!f IF( lk_bdy .AND. lk_dynspg_ts ) CALL bdy_vol( kt ) }}} into this subroutine might fix the problem. /Joakim " Bug closed low BDY v3.6 minor duplicate BDY DYN VVL v3.6 davestorkey
