This page describes the directory structure of the LMDZ longitude-latitude dynamical core and its main contents
The LMDZ.COMMON directory
Once download from the svn server, the LMDZ.COMMON directory contents should be:
arch build_gcm ioipsl Licence_CeCILL_V2-en.txt makelmdz bld.cfg create_make_gcm libf Licence_CeCILL_V2-fr.txt makelmdz_fcm
Where the noteworthy elements are:
- The makelmdz_fcm script, which is required to compile the model; see the dedicated page
- The arch directory which contains architecture files used by the makelmdz_fcm script
- The ioipsl directory which contains some scripts to assist one in installing the IOIPSL library
- The libf directory which contains the Fortran source code (see below).
The libf subdirectory
The libf directory contains a mix of subdirectories or links to subdirectories:
aeronomars dyn3d dynphy_lonlat misc phymars phyvenus aeronostd dyn3d_common filtrez muphytitan phystd chimtitan dyn3dpar grid phy_common phytitan
The general idea here is that there is both a clean (and hopefully clear) separation between dynamics, physics and interfaces between the two. In addition to this principle comes the fact that there are various physics packages (Mars, Venus, Titan, Generic) and that the dynamical core comes in two flavors, serial and parallel. One can thus identify the following groups:
- "dynamics"-related directories: dyn3d: routines specific to the serial dynamical core, dy3dpar: routines specific to the parallel dynamical core, dyn3d_common: routines used by both serial and parallel dynamical cores. In addition grid and filtrez directories also contain routines used by the dynamical cores and respectively related to the (horizontal) grid and polar filter.
- "physics"-related directories: links to physics directories specific to the various physics packages (e.g. phystd and aeronostd are respectively links to the Generic physics ../../LMDZ.GENERIC/libf/phystd and ../../LMDZ.GENERIC/libf/aeronostd directories), along with phy_common, a directory containing routines common to all the physics packages.
- dynphy_lonlat: directory which contains the interface between the (lon-lat) dynamical core and physics packages, i.e routines which are thus connected to both. In addition, it also hosts some pre/post processing utilities (e.g. newstart, start2archive) which need access both the LMDZ.COMMON (lon-lat) dynamics and relevant physics packages.
- misc: this directory contains miscellaneous routines which may be used either by the dynamics or physics but which rely on neither.
