polaris.tasks.ocean.single_column.frazil.melting_short.FrazilMeltingShort

class polaris.tasks.ocean.single_column.frazil.melting_short.FrazilMeltingShort(component, subdir, name, variant_cfg)[source]

A two-layer single-column frazil test with a warm top layer over a supercooled bottom layer and no surface forcing. All tendencies are disabled except frazil, so the evolution of both layers is set entirely by frazil formation and melting. Omega runs each of its time integrators with both frazil algorithms ('FixedProperty' and 'teos'). MPAS-Ocean retains only RK4 with 'FixedProperty'.

__init__(component, subdir, name, variant_cfg)[source]

Create the test case

Parameters:

  • component (polaris.tasks.ocean.Ocean) – The ocean component that this task belongs to

  • subdir (str) – The directory the task is in

  • name (str) – The task name

  • variant_cfg (str) – A config overlay in this package setting the initial temperature for this variant

Methods

__init__(component, subdir, name, variant_cfg)

Create the test case

add_step([step, subdir, symlink, run_by_default])

Add a step to the task and component (if not already present)

configure()

Keep only the RK4 'FixedProperty' forward step if the ocean model is MPAS-Ocean, which supports neither the other time integrators nor the 'teos' algorithm

remove_step(step)

Remove the given step from this task and the component

set_shared_config(config[, link])

Replace the task's config parser with the shared config parser
