Use CASEROOT tools xmlquery to query these variables and xmlchange to change their values.

Parameter Name Default Value Data Type Group CASEROOT File Valid Values Description
COMP_GLC cism char case_comp env_case.xml ['cism']
b'Name of land ice-sheet component'
CISM_USE_TRILINOS FALSE logical build_component_cism env_build.xml ['TRUE', 'FALSE']
b'TRUE implies CISM is built with support for the trilinos library\n      When using the higher-order dynamical cores in CISM, one option is to\n      use the trilinos solver library for sparse matrix solves. In order to\n      exercise that option, you need to build CISM with trilinos support, and\n      link to the trilinos libraries when building the CESM executable. Setting\n      this variable to TRUE accomplishes these things. Note that you can set\n      this to TRUE and still choose not to use the trilinos solvers for the\n      sparse matrix solves. Also, note that trilinos is only available on a\n      limited set of machines; this must remain FALSE to run CISM on a\n      machine that does not have trilinos, or for which the CESM scripts are\n      not aware of the existence of trilinos.'
CISM_PHYS cism1 char run_component_cism env_run.xml ['cism1', 'cism2']
b'Version of CISM physics/dynamics to use'
CISM_EVOLVE FALSE logical run_component_cism env_run.xml ['TRUE', 'FALSE']
b'Whether CISM ice evolution is on or off.\n\n     Setting CISM_EVOLVE to FALSE in a hybrid case also forces the use\n     of observed initial conditions, as if you had also set\n     CISM_OBSERVED_IC=TRUE.\n     '
CISM_OBSERVED_IC FALSE logical run_component_cism env_run.xml ['TRUE', 'FALSE']
b'For hybrid runs, whether CISM should use observed initial\n    conditions instead of restart file.\n\n    For hybrid runs, a value of FALSE (default) implies that CISM should\n    use the restart file from the reference case; a value of TRUE\n    implies that CISM should instead use the observed initial conditions\n    that are generally used for startup runs. This variable is ignored\n    for startup runs; for branch runs, it must be FALSE.\n\n    Note that setting CISM_EVOLVE to FALSE in a hybrid case also forces\n    the use of observed initial conditions, as if you had also set\n    CISM_OBSERVED_IC=TRUE.\n    '
