compass.ocean.tests.sphere_transport.nondivergent_2d.forward.Forward

class compass.ocean.tests.sphere_transport.nondivergent_2d.forward.Forward(test_case, resolution, dt_minutes)

A step for performing forward MPAS-Ocean runs as part of the

nondivergent_2d test case.

Variables:

resolution (int) – The resolution of the (uniform) mesh in km

__init__(test_case, resolution, dt_minutes)

Create a new step

Parameters:

• test_case (compass.ocean.tests.global_convergence.nondivergent_2d.Nondivergent2D) – The test case this step belongs to

• resolution (int) – The resolution of the (uniform) mesh in km

• dt_minutes (int) – The time step size in minutes. must divide 1 day (24*60)

Methods

__init__(test_case, resolution, dt_minutes)	Create a new step
add_input_file([filename, target, database, ...])	Add an input file to the step (but not necessarily to the MPAS model).
add_model_as_input()	make a link to the model executable and add it to the inputs
add_namelist_file(package, namelist[, ...])	Add a file with updates to namelist options to the step to be parsed when generating a complete namelist file if and when the step gets set up.
add_namelist_options(options[, out_name, mode])	Add the namelist replacements to be parsed when generating a namelist file if and when the step gets set up.
add_output_file(filename)	Add the output file that must be produced by this step and may be made available as an input to steps, perhaps in other test cases.
add_streams_file(package, streams[, ...])	Add a streams file to the step to be parsed when generating a complete streams file if and when the step gets set up.
constrain_resources(available_resources)	Update resources at runtime from config options
get_timestep_str()	These tests expect the time step to be input in units of minutes, but MPAS requires an "HH:MM:SS" string.
process_inputs_and_outputs()	Process the inputs to and outputs from a step added with compass.Step.add_input_file() and compass.Step.add_output_file().
run()	Run this step of the testcase
runtime_setup()	Update attributes of the step at runtime before calling the run() method.
set_resources([cpus_per_task, ...])	Update the resources for the subtask.
setup()	Set namelist options base on config options
update_namelist_at_runtime(options[, out_name])	Update an existing namelist file with additional options.
update_namelist_pio([out_name])	Modify the namelist so the number of PIO tasks and the stride between them consistent with the number of nodes and cores (one PIO task per node).
update_streams_at_runtime(package, streams, ...)	Update the streams files during the run phase of this step using the given template and replacements.
