newmicro.F @ 5447

Last change on this file since 5447 was 1525, checked in by idelkadi, 14 years ago

Modifications concerning the cloud scheme:

In newmicro, it now possible to read a min and max effective radius of ice particles from physiq.def : rei_min and rei_max which were initially set to 3.5 and 61.29 microns in the code.

concerns : conf_phys.F90, nuage.h, newmicro.F

In physiq.F, in case of combination of iflag_cldcon>=5 (A. Jam cloud scheme) and iflag_coupl=5

concerns : physiq.F and thermcell_main.F90
