! At the exterior edge of Mesh NM, which abuts Mesh NOM, assign the appropriate velocity component to the
! ghost cell. For example, MESHES(NM)%VV(IBP1,JJ,KBP1) is stored in MESHES(NM)%OMESH(NOM)%V(IIO+1,JJO,KKO) if Mesh
! NOM is above Mesh NM (IOR=-3), or it is stored in MESHES(NM)%OMESH(NOM)%V(IIO,JJO,KKO+1) if Mesh NOM is to
! the right of NM (IOR=-1). The value of each is the same and it is transfered to Mesh NM with a one-step time lag.
