[Mitgcm-support] initial w and cyclic bc's

[mitgcm-support at dev.mitgcm.org]

Why has the line that updates the overlaps been
commented out in model/src/ini_vel.F?

C     Read an initial state for each component if required
      IF (uVelInitFile .NE. ' ') THEN
       _BEGIN_MASTER( myThid )
       CALL READ_FLD_XYZ_RL( uVelInitFile, ' ', uVel, 0, myThid )
       _END_MASTER(myThid)
c      _EXCH_XYZ_R8(uVel  , myThid )
      ENDIF

The above implies that any cyclic b.c.'s in u,v are 
not accounted for prior to initializing w. Accordingly
large initial vertical velocities are set up at the
eastern and northern boundaries.
