More on physics/dynamics separation and cleanup:

  • Set things up so that all physics-related initializations are done via iniphysiq.
  • Created a "geometry_mod.F90" module in phy_common to store information on the loacl grid (i.e. replaces comgeomphy) and moreover give these variables more obvious names (e.g.: rlond => longitude, rlatd => latitude, airephy => cell_area).
  • removed obsolete comgeomphy.h and comgeomphy.F90
