and change the line that says |

|
|

The time-step is 600 seconds, so this will integrate the model for 10 days. |
| 27 |
|
|
Hopefully, it will finish well before that. ;^) |
| 28 |
|
|
<p>Re-run the model: |
| 29 |
|
|
<blockquote> |
| 30 |
|
|
<pre>% ./mitgcmuv > output.txt</pre> |
| 31 |
|
|
</blockquote> |
| 32 |
|
|
When the model finishes, you'll notice more output files: |
