Revision 20 - (hide annotations)
Wed Oct 15 16:19:57 2008 UTC (15 years, 7 months ago) by guez
Original Path: trunk/libf/dyn3d/grid_change.f90
File size: 3103 byte(s)
Deleted argument "presnivs" of "physiq", "ini_histhf", "ini_histhf3d",
"ini_histday", "ini_histins", "ini_histrac", "phytrac". Access it from
"comvert" instead.

Replaced calls to NetCDF Fortran 77 interface by calls to Fortran 90
interface or to NetCDF95.

Procedure "gr_phy_write_3d" now works with a variable of arbitrary
size in the second dimension.

Annotated use statements with "only" clause.

Replaced calls to NetCDF interface version 2 by calls to Fortran 90
interface in "guide.f90" and "read_reanalyse.f".

In "write_histrac", replaced calls to "gr_fi_ecrit" by calls to
"gr_phy_write_2d" and "gr_phy_write_3d".
