======= VENUS PCM ===============

COMMIT BY ANTOINE MARTINEZ

Implementation of vertical ambipolar diffusion in physics

=================================

NEW KEYWORD OF PHYSIQ.DEF

=================================

NEW VERSION OF "physiq.def"

  • deftank/physiq-96x96x90-chemistry-IONOSPHERE-IONDIFF.def
  • ok_iondiff: keyword supposed to activate ion ambipolar diffusion
  • nbapp_chem: replaces nbapp_chim, in order to characterize the Number of calls to the chemistry routines (per Venusian day)

================

phyvenus

================

Iondiff_red.F

  • Calculation of the Ion Ambipolar Diffusion for 13 ions on 14:

O2+, O+, C+, N+, CO2+,
NO+, CO+, H+, H2O+, H3O+,

HCO+, N2+, OH+


The ion temperature is fixed as the half of the electron temperature
calculated in ion_h.F for the stability of the program and because the
ion temperature is lower than electron temperature.

plasmaphys_venus_mod.F90

  • parameters of the ambipolar diffusion scheme:

parameter (Pdiffion = 7.0D-4) ! pressure in Pa below which ion diffusion is computed
parameter (naltvert = 168) ! number of level on the altimetric subgrid
parameter (nsubvert = 24000) ! ptimephysiq/nsubvert - minimum sub-timestep allowed
parameter ( nsubmin = 40) ! ptimephysiq/nsubmin - maximum sub-timestep allowed

physic_mod.F

  • nbapp_chem is not fixed anymore here but deftank/in physiq.def
  • Ambipolar diffusion activated if (ok_iondiff) is true

conf_phys.f90

  • add ok_iondiff as parameters to read from physiq.def file set to .false. by default
  • add nbapp_chem as parameters to characterize the Number of calls to the chemistry routines (per Venusian day) instead of be fixed in physic_mod.F

to read from physiq.def file set to 24000 by default

cleshphys.h

  • added ok_iondiff & nbapp_chem in COMMON/clesphys_l/
  • removed nbapp_chim

phytrac_chemistry.F

  • Added security in the calculation of the sza_local in order to avoid the rare case where the |range| is above 1
