Original Path: trunk/libf/dyn3d/rotatf.f
File size: 1549 byte(s)
Removed unused procedure "divgrad".

In procedure "dissip", save memory by using intermediary arrays "gdx"
and "gdy" several times instead of additional array "grx" and "gry".

In procedure "inidissip", write "dtdiss * teta*" instead of "teta*".

In "comvert", change name of s_sampling from "LMD5" to "tropo" and
from "strato2" to "strato".
