! Loop over the coarse grid in the area of the fine mesh. Do not
! process the coarse grid values that are along the lateral BC
! provided to the fine grid. Since that is in the specified zone
! for the fine grid, it should not be used in any feedback to the
! coarse grid as it should not have changed.
! Due to peculiarities of staggering, it is simpler to handle the feedback
! for the staggerings based upon whether it is a even ratio (2::1, 4::1, etc.) or
! an odd staggering ratio (3::1, 5::1, etc.).
! Though there are separate grid ratios for the i and j directions, this code
! is not general enough to handle aspect ratios .NE. 1 for the fine grid cell.
! These are local integer increments in the looping. Basically, istag=1 means
! that we will assume one less point in the i direction. Note that ci and cj
! have a maximum value that is decreased by istag and jstag, respectively.
! Horizontal momentum feedback is along the face, not within the cell. For a
! 3::1 ratio, temperature would use 9 pts for feedback, while u and v use
! only 3 points for feedback from the nest to the parent.

! in the parent domain (ipos,jpos - i_parent_start and j_parent_start from

! For each of the CG points, the feedback loop is over each of the FG points
! within the CG cell. For a 2::1 ratio, there are four total points (this is
! the ijpoints loop). The feedback value to the CG is the arithmetic mean of
! all of the FG values within each CG cell.
