Revision 145 - Directory Listing
Modified Tue Jun 16 15:23:29 2015 UTC (8 years, 10 months ago) by guez

Renamed bibio to misc.

In procedure fxhyp, use the fact that xf is an odd function of xtild.

In procedure invert_zoom_x, replace linear search in xf by
bisection. Also, use result from previous loop iteration as initial
guess. Variable "it" cannot be equal to 2 * nmax after search.

Unused arguments: hm of cv3_feed; ph, qnk, tv,tvp of cv3_mixing; ppsol
of lw; rconst, temp of vdif_kcay; rconst, plev, temp, ustar, l_mix of
yamada.

In procedure fxhyp, the convoluted computation of tanh(fa/fb) occurred
three times. Extracted it into a function. Also, the computation of
xmoy and fxm was repeated. So stored the values in arrays instead.

In procedure fxhyp, in the computation of fhyp, there were tests
xtild(i) == 0. and xtild(i) == pi_d. No use to do these tests at each
iteration. We now they are true for i == nmax and i == 2 * nmax,
respectively, and we know they are false for other values of
"i". Similarly, in the computations of ffdx and xxpr, there were the
tests xmoy == 0. and xmoy == pi_d, these could not be true.

Moved files from bibio to dyn3d, following LMDZ.

Modified Tue Jun 9 14:32:46 2015 UTC (8 years, 10 months ago) by guez

Removed argument d of procedure acc. Was probably here just because
automatic arrays were unknown.

eigen_sort was eigsrt from Numerical Recipes.

In procedure inifilr, create file "eignvl.txt" instead of writing to
standard output.

Procedure filtreg_hemisph is always called with sdd2 = 1 / sdd1. It
would not make sense otherwise. I do not like that this does not
appear explicitly in filtreg_hemisph. So replaced the two arguments
sdd1 and sdd2 by a single argument sdd. The cost is computing a
division instead of multplication for every 3-dimensional
position. Besides, this changes the results.

Revision 140 - Directory Listing
Modified Fri Jun 5 18:58:06 2015 UTC (8 years, 11 months ago) by guez

Changed unit of variables lat_min_guide and lat_max_guide from module
conf_guide_m from degrees to rad. Then we do not have to convert the
whole array rlat from rad to degrees in SUBROUTINE tau2alpha.

Removed some useless computations in inigeom.

Removed module coefils. Moved variables sddv, unsddv, sddu, unsddu,
eignfnu, eignfnv of module coefils to module inifgn_m. Downgraded
variables coefilu, coefilu2, coefilv, coefilv2, modfrstu, modfrstv of
module coefils to local variables of SUBROUTINE inifilr.

Write and read a 3-dimensional variable Tsoil in restartphy.nc and
startphy.nc instead of multiple variables for the different
subs-urfaces and soil layers. This does not allow any longer to
provide only the surface value in startphy.nc and spread it to other
layers. Instead, if necessary, pre-process the file startphy.nc to
spread the surface value.

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.

Modified Fri May 22 23:13:19 2015 UTC (8 years, 11 months ago) by guez

Moved variable nb_files from module histcom_var to module
histbeg_totreg_m.

Removed unused argument q of writehist.

No history file is created in program ce0l so there is no need to call
histclo in etat0.

In phyredem, access variables rlat and rlon directly from module
phyetat0_m instead of having them as arguments. This is clearer for
the program gcm. There are bad side effects for the program ce0l: we
have to modify the module variables rlat and rlon in procedure etat0,
and we need the additional file phyetat0.f to compile ce0l.

Revision 137 - Directory Listing
Modified Wed May 6 15:51:03 2015 UTC (9 years ago) by guez

Removed unused argument missval in ma_fucoll_r[1-3]1, ma_fufill_r[1-3]1.

Split filtreg into two procedures: filtreg_scal and filtreg_v. I did
not like the test on the extent of the argument and there was no
common code between the two cases: jjm and jjm + 1. Also, it is
simpler now to just remove the argument "direct" from filtreg_v instead
of allowing it and then stopping the program if it is false.

Removed the computation of pkf in reanalyse2nat, was not used.

As a consequence of the split of filtreg, had to extract the
computation of pkf out of exner_hyb. This is clearer anyway because we
want to be able to call exner_hyb with any size in the first two
dimensions (as in test_disvert). But at the same time exner_hyb
required particular sizes for the computation of pkf. It was
awkward. The only computation of pkf is now in leapfrog.

Revision 136 - Directory Listing
Modified Thu Apr 30 18:35:49 2015 UTC (9 years ago) by guez

Clarified the logic in filtreg by creating a procedure
filtreg_hemisph. It was terrible with a loop on hemispheres and tests
on hemisphere inside the loop, plus maddening indirections on latitude
bounds, plus repeated code. Went from 126 lines to much clearer 74 +
32 = 106 lines.

In module inifilr_m, finally made the arrays matrice[uv][ns],
matrinv[ns] dynamic (following LMDZ). Changed the lower bound of
matriceun and matrinvn in the 3rd dimension: 2 instead of 1, the index
1 was not defined (nor used).

In module inifilr_m, changed the bounds of matriceus and matrinvs in
the 3rd dimension: jfiltsu:jjm instead of 1:jjm - jfiltsu + 1. Changed
the bounds of matricevs in the 3rd dimension: jfiltsv:jjm instead of
1:jjm - jfiltsv + 1. It is a little simpler and clearer this way in
procedure inifilr.
