| 35 | ! Description: |
---|
| 36 | ! ------------ |
---|
| 37 | ! Advection term for scalar quantities using the Bott-Chlond scheme. |
---|
| 38 | ! Computation in individual steps for each of the three dimensions. |
---|
| 39 | ! Limiting assumptions: |
---|
| 40 | ! So far the scheme has been assuming equidistant grid spacing. As this is not |
---|
| 41 | ! the case in the stretched portion of the z-direction, there dzw(k) is used as |
---|
| 42 | ! a substitute for a constant grid length. This certainly causes incorrect |
---|
| 43 | ! results; however, it is hoped that they are not too apparent for weakly |
---|
| 44 | ! stretched grids. |
---|
| 45 | ! NOTE: This is a provisional, non-optimised version! |
