C !DESCRIPTION: |
19 |
|
|
C Calculates the tendancy of a tracer due to advection. |
20 |
|
|
C It uses the multi-dimensional method given in \ref{sect:multiDimAdvection} |
21 |
|
|
C and can only be used for the non-linear advection schemes such as the |
22 |
|
|
C direct-space-time method and flux-limiters. |
23 |
|
|
C |
24 |
|
|
C The algorithm is as follows: |
25 |
|
|
C \begin{itemize} |
26 |
|
|
C \item{$\theta^{(n+1/3)} = \theta^{(n)} |
27 |
adcroft |
1.5 |
C - \Delta t \partial_x (u\theta^{(n)}) + \theta^{(n)} \partial_x u$} |
28 |
adcroft |
1.4 |
C \item{$\theta^{(n+2/3)} = \theta^{(n+1/3)} |
29 |
adcroft |
1.5 |
C - \Delta t \partial_y (v\theta^{(n+1/3)}) + \theta^{(n)} \partial_y v$} |
30 |
adcroft |
1.4 |
C \item{$\theta^{(n+3/3)} = \theta^{(n+2/3)} |
31 |
adcroft |
1.5 |
C - \Delta t \partial_r (w\theta^{(n+2/3)}) + \theta^{(n)} \partial_r w$} |
32 |
adcroft |
1.4 |
C \item{$G_\theta = ( \theta^{(n+3/3)} - \theta^{(n)} )/\Delta t$} |
33 |
|
|
C \end{itemize} |
34 |
|
|
C |
35 |
|
|
C The tendancy (output) is over-written by this routine. |
