greenland test group (
performs short (5-day) forward runs on a coarse (20-km) Greenland mesh, and creates
a variable resolution mesh based on user inputs (see greenland).
Here, we describe the shared framework for this test group and the 4 test cases.
There are no shared config options for the
greenland test group.
Each of the tests and the
RunModel step require an argument for
velo_solver that can be one of
['sia', 'FO']. When a test is set
up to use the ‘FO’ solver, COMPASS will adjust the namelist accordingly
and add a copy of the
albany_input.yaml input file required by the FO
solver. Running with the FO solver requires building MALI with the Albany
The test group has a shared
namelist.landice file with
a few common namelist options related to time step, run duration and calving,
and a shared
streams.landice file that defines

restart_test test cases, the model will run multiple times with
different namelist and streams files. To support this functionality, this step
has an attribute
suffixes, which is a list of suffixes for the these
namelist and streams files. The model runs once for each suffix. The default
defines a step for creating a variable resolution Greenland Ice Sheet mesh.
This is used by the
mesh_gen test case.

The restart step works by creating two different namelist and streams files,
one each with
landice as the suffix and one each with
the suffix. The former perform a 3-day run from the initial condition, while
the latter perform a 2-day restart run beginning with the end of the first.
