c o Set parts of the vector of control variables and initialize the |

c rest to zero. |
| 16 |
c |
| 17 |
c The vector of control variables is initialized here. The |
| 18 |
c temperature and salinity contributions are read from file. |
| 19 |
c Subsequently, the latter are dimensionalized and the tile |
| 20 |
c edges are updated. |
