Two time-stepping strategies have been implemented, one in Paris and one in Toulouse. The former is described in Leclair and Madec (OM 2009), the latter is based on Shchepetkin and McWilliams (OM 2005) work. The objective here is to intercompare the two solutions and either chose the best or improve the co-existence of the two time stepping (more readability and reduce the number of modules) [[BR]] 18 19 '''Status :''' Paris time stepping already in the trunk (v3.2), Toulouse' one will be committed early 2010 (cf C.4, v3.3) [[BR]] 19 '''main tasks :''' (24w ) [[BR]]20 (1) intercomparison of the 2 time stepping strategies in ORCA and facade configurations (12w ) [[BR]]21 (2) either chose one time stepping strategy or improve the co-existence of the two (12w ) (v3.4) [[BR]]20 '''main tasks :''' (24wk) [[BR]] 21 (1) intercomparison of the 2 time stepping strategies in ORCA and facade configurations (12wk) [[BR]] 22 (2) either chose one time stepping strategy or improve the co-existence of the two (12wk) (v3.4) [[BR]] 22 23 '''Principal Investigator :''' Rachid Benshila (rachid.benshila@locean-ipsl.upmc.fr) [[BR]] 23 24 24 25 25 26 [[BR]] 26 == '''A.2 — Configuration manager'''==27 === '''A.2 — Configuration manager''' === 27 28 '''Motivation:''' Create the configuration tools (CFG-tools): user-friendly interface, the tools, and the documentation associated to the creation of a new model configuration, and especially configurations defined as a zoom of an ORCA configuration.
