---|
38 | !! ocean domain informations (mesh and mask arrays). This (these) |

39 | !! file(s) is (are) used for visualisation (SAXO software) and |
---|
40 | !! diagnostic computation. |
---|
41 | !! |
---|
42 | !! ** Method : Write in a file all the arrays generated in routines |
---|
43 | !! domhgr, domzgr, and dommsk. Note: the file contain depends on |
