Revision 212 - (hide annotations)
Thu Jan 12 12:31:31 2017 UTC (7 years, 4 months ago) by guez
Original Path: trunk/Sources/dyn3d/grille_m.f
File size: 3818 byte(s) 
Moved variables from module com_io_dyn to module inithist_m, where
they are defined.

Split grid_atob.f into grille_m.f and dist_sphe.f. Extracted ASCCI art
to documentation. In grille_m, use automatic arrays instead of maximum
size. In grille_m, instead of printing data for every problematic
point, print a single diagnostic message.

Removed variables top_height, overlap, lev_histhf, lev_histday,
lev_histmth, type_run, ok_isccp, ok_regdyn, lonmin_ins, lonmax_ins,
latmin_ins, latmax_ins of module clesphys, not used.

Removed variable itap of module histwrite_phy_m, not used. There is a
variable itap in module time_phylmdz.

Added output of tro3.

In physiq, no need to compute wo at every time-step, since we only use
it in radlwsw.
