source: trunk/LMDZ.GENERIC/libf/phystd/inifis_mod.F90 @ 1626

Last change on this file since 1626 was 1542, checked in by emillour, 9 years ago

Generic GCM:

  • fix for 1D in writediagfi to enable writing at "ecritphy" rate.
  • move iniprint.h to "misc"
  • Some code cleanup in anticipation of future updates:
    • changed variable names in comgeomphy.F90: give them more explicit names: rlond => longitude , rlatd => latitude, airephy => cell_area, cuphy => dx , cvphy => dy
    • removed long(), lati() and area() from comgeomfi_h.F90, use longitude(), latitude() and cell_are() from comgeomphy.F90 instead
