#**************************************************************************
#           Suggested parameter set up for ORCHIDEE trunk
#
# See all optional parameters in modipsl/modeles/ORCHIDEE/orchidee.default
#
# Note when running with libIGCM, variables set here to _AUTOBLOCKER_ can 
# not be changed in run.def otherwise the simulation will stop. Variables 
# set to _AUTO_ can be changed from the comp.card but they can also be 
# changed directly in the run.def. A value set in run.def can never be
# changed again by libIGCM. 
#**************************************************************************

# Parameters that should be removed once these issues are resolved
#**************************************************************************

# From a scientific point of view hydraulic architecture is much nicer
# than a direct dependency on soil water. Julien is working on both
# the nummerics and the science of the hydraulic architecture. To
# avoid further delays with milestone 4.1 we decided to change the
# settings.

# Parameters related to debugging and error checking
#**************************************************************************
# Mass balance and surface area checks
# 1 - is recommended when running global long-term simulations.
# Under this option, mass and area conservation are checked for all
# biogeochemical processes but only at the highest level thus stomate.f90
# and stomate_lpj.f90. Although these checks are not very expensive in terms
# of computer time, skipping the numerous lower level checks is expected to
# save some time. Under this option the mass balance error is only written
# to the history file. No information is provided in which subroutine the
# problem occurred.
# 2 - is recommended when developing and testing the model. Now the mass
# balance is explicitly checked in stomate.f90, stomate_lpj.f90 and all
# its subroutines. Under this option the mass balance error is written to
# the history file and if the mass balance is not closed, the warning
# message will indicate in which subroutine the problem likely
# originated.
# 3 - is recommended when having a problem with mass balance closure. The
# mass balance is explicitly checked in stomate.f90, stomate_lpj.f90 and all
# its subroutines. If a mass balance occurs, the model is stopped.
# (default)
ERR_ACT = 3

# If the model crashes and it is not clear in which subroutine the crash
# occurs one could increase the print level for text output in out_orchidee_*

# PRINTLEV = 3, 4,.. : more output also at each timestep
# (default 2)
PRINTLEV=1

# If the model crashes on an ipslerr there is a fair change that the pixel and
# PFT where the crash occur will be printed in the out_orchidee_* file. Try to
# re-run the model for a single pixel or a small region (for example,
# 3 by 3). LIMIT_EAST, LIMIT_NORTH, LIMIT_SOUTH and LIMIT_WEST should
# be set in the run.def 

# If it is known in which subroutine the model crashes, the local print level
# of that subroutine could be increased. Additional write statements will then
# be activated. These write statements print the values of specific variables.
# (default 2)
#PRINTLEV_sapiens_lcchange = 4
