Currently, this test will fail.

| 2 | Joaquim Luis discovered that ANUGA misinterpreted the xllcorner and yllcorner |
|---|
| 3 | parameters and devised this test to reveal the problem. See sourceforge mailing thread: http://sourceforge.net/mailarchive/forum.php?thread_name=4727D555.7010208%40ualg.pt&forum_name=anuga-user |

| 5 | For testing purposes, the script was modified with use_cache=False. |

| 7 | The error manifests itself when the dem (sub_region.asc, sub_region.prj) and the polygons (shallow.csv, out_rect.csv) in turned into a domain and the boundary condition defined in br_swan.sww is applied. With wrong pixel registration, the domain will be out by 0.5*cellsize and therefor outside the area covered by |
|---|
| 8 | the boundary condition. |

| 10 | After Joaquim's fix (November 2007), this passed. |
