669 | !! ** Purpose : set lateral boundary conditions on a 2D array (non mpp case) |
---|
670 | !! special dummy routine to allow for use of halo indexing in mpp case |
---|
671 | !! |
---|
672 | !! ** Method : psign = -1 : change the sign across the north fold |
---|
673 | !! = 1 : no change of the sign across the north fold |
---|
674 | !! = 0 : no change of the sign across the north fold and |
---|
675 | !! strict positivity preserved: use inner row/column |
---|
676 | !! for closed boundaries. |
