mirror_bdy_2d() - mirrors 2d variables (Source File: mirror_bdy_2d.F90)

INTERFACE:

    subroutine mirror_bdy_2d(f,tag)

DESCRIPTION:

Some variables are mirrored outside the calculation domain in the vicinity of the open boundaries. This is to avoid if statements when calculating e.g. the Coriolis terms and advection. This routines mirrors 2d variables. USES:

    use halo_zones, only : U_TAG,V_TAG,H_TAG
    use domain, only: imin,imax,jmin,jmax
    use domain, only: az,au,av
    use domain, only: NWB,NNB,NEB,NSB
    use domain, only: wi,wfj,wlj,nj,nfi,nli,ei,efj,elj,sj,sfi,sli
    IMPLICIT NONE
