Venus and Titan GCMs:
Updates in the physics to keep up with updates in LMDZ5 (up to
LMDZ5 trunk, rev 2350) concerning dynamics/physics separation:

  • Adapted makelmdz and makelmdz_fcm script to stop if trying to compile 1d model or newstart or start2archive in parallel.
  • got rid of references to "dimensions.h" in physics. Within physics packages, use nbp_lon (=iim), nbp_lat (=jjmp1) and nbp_lev (=llm) from module mod_grid_phy_lmdz (in phy_common) instead. Only partially done for Titan, because of many hard-coded commons; a necessary first step will be to clean these up (using modules).
