C *==========================================================* |

C | S/R DEBUG_CS_CORNER_UV | |
| 12 |
C | o check UV fields at Egdes of CS grid, near corners. | |
| 13 |
C *==========================================================* |
| 14 |
C | Values of U,V fields at the Edges of the CS grid | |
| 15 |
C | are common to 2 faces, and are stored + used in 2 | |
| 16 |
C | places (2 tiles): one in the interior of the 1rst tile, | |
| 17 |
C | the other in the halo of the 2nd one. | |
| 18 |
C | This S/R print the 2 values and check that they are | |
| 19 |
C | identical (print the difference). | |
| 20 |
C | This is specially usefull for checking that gU,gV are | |
| 21 |
C | correct before entering solve_for_pressure. | |
| 22 |
C *==========================================================* |
