---|
| 65 | ! Description: |
---|
| 66 | ! ------------ |
---|
| 67 | ! Advection term for scalar quantities using the Bott-Chlond scheme. |
---|
| 68 | ! Computation in individual steps for each of the three dimensions. |
---|
| 69 | ! Limiting assumptions: |
---|
| 70 | ! So far the scheme has been assuming equidistant grid spacing. As this is not |
---|
| 71 | ! the case in the stretched portion of the z-direction, there dzw(k) is used as |
---|
| 72 | ! a substitute for a constant grid length. This certainly causes incorrect |
---|
| 73 | ! results; however, it is hoped that they are not too apparent for weakly |
---|
| 74 | ! stretched grids. |
---|
| 75 | ! NOTE: This is a provisional, non-optimised version! |
