parameters). |
These files should contain 3D data ordered in an (x,y,r) fashion with |
| 208 |
|
k=1 as the first vertical level (surface level). |
| 209 |
|
If no file names are provided, the velocity is initialised to zero. |

|
The initial vertical velocity is always derived from the horizontal velocity |
| 211 |
|
using the continuity equation, even in the case of non-hydrostatic simulation |

(see, e.g.: {\it tutorial\_deep\_convection/input/data}). |

In the case of a restart (from the end of a previous simulation), |
| 215 |
|
the velocity field is read from a pickup file |
| 216 |
|
(see section on simulation control parameters) |
| 217 |
|
and the initial velocity files are ignored. |
