---|
52 | !> Advection term for scalar quantities using the Bott-Chlond scheme. |
---|
53 | !> Computation in individual steps for each of the three dimensions. |
---|
54 | !> Limiting assumptions: |
---|
55 | !> So far the scheme has been assuming equidistant grid spacing. As this is not the case in the |
---|
56 | !> stretched portion of the z-direction, there dzw(k) is used as a substitute for a constant grid |
---|
57 | !> length. This certainly causes incorrect results; however, it is hoped that they are not too |
---|
58 | !> apparent for weakly stretched grids. |
---|
59 | !> NOTE: This is a provisional, non-optimised version! |
