Revision Log
| Sticky Revision: |
Just encapsulated SUBROUTINE vlsplt in a module and cleaned it. In procedure vlx, local variables dxqu and adxqu only need indices iip2:ip1jm. Otherwise, just cleaned vlx. Procedures dynredem0 and dynredem1 no longer have argument fichnom, they just operate on a file named "restart.nc". The programming guideline here is that gcm should not be more complex than it needs by itself, other programs (ce0l etc.) just have to adapt to gcm. So ce0l now creates files "restart.nc" and "restartphy.nc". In order to facilitate decentralizing the writing of "restartphy.nc", created a procedure phyredem0 out of phyredem. phyredem0 creates the NetCDF header of "restartphy.nc" while phyredem writes the NetCDF variables. As the global attribute itau_phy needs to be filled in phyredem0, at the beginnig of the run, we must compute its value instead of just using itap. So we have a dummy argument lmt_pas of phyredem0. Also, the ncid of "startphy.nc" is upgraded from local variable of phyetat0 to dummy argument. phyetat0 no longer closes "startphy.nc". Following the same decentralizing objective, the ncid of "restart.nc" is upgraded from local variable of dynredem0 to module variable of dynredem0_m. "restart.nc" is not closed at the end of dynredem0 nor opened at the beginning of dynredem1. In procedure etat0, instead of creating many vectors of size klon which will be filled with zeroes, just create one array null_array. In procedure phytrac, instead of writing trs(: 1) to a text file, write it to "restartphy.nc" (following LMDZ). This is better because now trs(: 1) is next to its coordinates. We can write to "restartphy.nc" from phytrac directly, and not add trs(: 1) to the long list of variables in physiq, thanks to the decentralizing of "restartphy.nc". In procedure phyetat0, we no longer write to standard output the minimum and maximum values of read arrays. It is ok to check input and abort on invalid values but just printing statistics on input seems too much useless computation and out of place clutter.
dynetat0 read rlonu, rlatu, rlonv, rlatv, cu_2d, cv_2d, aire_2d from "start.nc" and then these variables were overwritten by inigeom. Corrected this. Now, inigeom does not compute rlonu, rlatu, rlonv and rlatv. Moreover, cu_2d, cv_2d, aire_2d are not written to "restart.nc". Since xprimu, xprimv, xprimm025, xprimp025, rlatu1, rlatu2, yprimu1, yprimu2 are computed at the same time as rlonu, rlatu, rlonv, rlatv, and since it would not be convenient to separate those computations, we decide to write xprimu, xprimv, xprimm025, xprimp025, rlatu1, rlatu2, yprimu1, yprimu2 into "restart.nc", read them from "start.nc" and not compute them in inigeom. So, in summary, "start.nc" contains all the coordinates and their derivatives, and inigeom only computes the 2D-variables. Technical details: Moved variables rlatu, rlonv, rlonu, rlatv, xprimu, xprimv from module comgeom to module dynetat0_m. Upgraded local variables rlatu1, yprimu1, rlatu2, yprimu2, xprimm025, xprimp025 of procedure inigeom to variables of module dynetat0_m. Removed unused local variable yprimu of procedure inigeom and corresponding argument yyprimu of fyhyp. Moved variables clat, clon, grossismx, grossismy, dzoomx, dzoomy, taux, tauy from module serre to module dynetat0_m (since they are read from "start.nc"). The default values are now defined in read_serre instead of in the declarations. Changed name of module serre to read_serre_m, no more module variable here. The calls to fxhyp and fyhyp are moved from inigeom to etat0. Side effects in programs other than gcm: etat0 and read_serre write variables of module dynetat0; the programs test_fxyp and test_inter_barxy need more source files. Removed unused arguments len and nd of cv3_tracer. Removed unused argument PPSOL of LWU. Bug fix in test_inter_barxy: forgotten call to read_serre.
Sources inside, compilation outside.
Changed all ".f90" suffixes to ".f".
Moved everything out of libf.
Changed name of module "comvert" to "disvert_m". Changed constant 1. to 0.3 in vertical sampling "strato".
Write used namelists to file "" instead of standard output. Avoid aliasing in "inidissip" in calls to "divgrad2", "divgrad", "gradiv2", "gradiv", "nxgraro2" and "nxgrarot". Add a degenerate dimension to arrays so they have rank 3, like the dummy arguments in "divgrad2", "divgrad", "gradiv2", "gradiv", "nxgraro2" and "nxgrarot". Extract the initialization part from "bilan_dyn" and make a separate procedure, "init_dynzon", from it. Move variables from modules "iniprint" and "logic" to module "conf_gcm_m". Promote internal procedures of "fxy" to private procedures of module "fxy_m". Extracted documentation from "inigeom". Removed useless "save" attributes. Removed useless intermediate variables. Extracted processing of poles from loop on latitudes. Write coordinates to file "longitude_latitude.txt" instead of standard output. Do not use ozone tracer for radiative transfer.
"start_init_phys" is now called directly by "etat0" instead of through "start_init_dyn". "qsol_2d" is no longer a variable of module "start_init_phys_m", it is an argument of "start_init_phys". "start_init_dyn" now receives "tsol_2d" from "etat0". Split file "vlspltqs.f" into "vlspltqs.f90", "vlxqs.f90" and ""vlyqs.f90". In "start_init_orog", replaced calls to "flin*" by calls to NetCDF95.
