ocean_periodic_wrap_face_y_2d Subroutine

public pure subroutine ocean_periodic_wrap_face_y_2d(fld, nx_total, ny_face, nx_phys, ny_phys, nghost, wrap_x, wrap_y)

Fill ghost faces of a 2D y-face field (e.g. bt_vbt, shape ny_total+1). Also copies south physical-wall face onto north physical-wall face. ny_face = ny_total + 1.
