Landice core¶

The landice core is defined by the compass.landice.LandIce class. All test cases in the landice core share the following set of default config options:

# This config file has default config options for the landice core

# The paths section points compass to external paths
[paths]

# the relative or absolute path to the root of a branch where MPAS-Ocean
# has been built
mpas_model = MALI-Dev/components/mpas-albany-landice

# The namelists section defines paths to example_compact namelists that will be used
# to generate specific namelists. By default, these point to the forward and
# init namelists in the default_inputs directory after a successful build of
# the landice model.  Change these in a custom config file if you need a different
# example_compact.
[namelists]
forward = ${paths:mpas_model}/default_inputs/namelist.landice

# The streams section defines paths to example_compact streams files that will be used
# to generate specific streams files. By default, these point to the forward and
# init streams files in the default_inputs directory after a successful build of
# the landice model. Change these in a custom config file if you need a different
# example_compact.
[streams]
forward = ${paths:mpas_model}/default_inputs/streams.landice


# The executables section defines paths to required executables. These
# executables are provided for use by specific test cases.  Most tools that
# compass needs should be in the conda environment, so this is only the path
# to the MPAS-Ocean executable by default.
[executables]
model = ${paths:mpas_model}/landice_model


# Options related to downloading files
[download]

# the path on the server for MALI
core_path = mpas-albany-landice

The default location for MALI is in the git submodule MALI-Dev in the directory components/mpas-albany-landice. The MALI-Dev submodule may not point to the latest update of the develop branch but the plan is to update the submodule frequently. The current version of the submodule should always be guaranteed to be compatible with the corresponding version of compass.

To make sure the code in the submodule has been cloned and is up-to-date, you should run

git submodule update --init --recursive

in the base directory of your local clone of the compass repo. Then, you can cd into MALI-Dev/components/mpas-albany-landice and build the code as appropriate for whichever of the Machines you are using.
