| 17 | | === Compile problem at ADA === |
| 18 | | With the default revision of LMDZ5 (rev 1729) there is a probleme with compiling medium resolutions. Error message is the following : |

| 21 | | }}} |
| 22 | | |
| 23 | | Solve this by updating arch files in LMDZ and recompile (rev 1906 in LMDZ/arch is ok) |
