Installation

Download

The complete and up-to-date set of test cases is available on :github:`NEMO test cases repository <NEMO-examples>`.

Download it directly into the :file:`./tests` root directory with

$ git clone http://github.com/NEMO-ocean/NEMO-examples

Compilation

The compilation of the test cases is very similar to the manner the reference configurations are compiled. If you are not familiar on how to compile NEMO, it is first recomended to read :doc:`the instructions <install>`.

As the reference configurations are compiled with -r option, test cases can be compiled by the use of :file:`makenemo` with -a option.

Here an example to compile a copy named WAD2 of the wetting and drying test case (WAD):

$ ./makenemo -n 'WAD2' -a 'WAD' -m 'my_arch' -j '4'

Run and analysis

There no requirement of specific input file for the test_cases presented here. The XIOS xml input files and namelist are already setup correctly. For detailed description and Jupyter notebook, the reader is directed on the :github:`NEMO test cases repository <NEMO-examples>`

The description below is a brief advertisement of some test cases.

List of test cases

ICE_AGRIF

This test case illustrates the advection of an ice patch across an East/West and North/South periodic channel over a slab ocean (i.e. one ocean layer), and with an AGRIF zoom (1:3) in the center.

The purpose of this configuration is to test the advection of the ice patch in and across the AGRIF boundary. One can either impose ice velocities or ice-atm. Stresses and let rheology define velocities (see :file:`README` for details)

VORTEX

This test case illustrates the propagation of an anticyclonic eddy over a Beta plan and a flat bottom. It is implemented here with an online refined subdomain (1:3) out of which the vortex propagates. It serves as a benchmark for quantitative estimates of nesting errors as in :cite:`DEBREU2012`, :cite:`PENVEN2006` or :cite:`SPALL1991`.

The animation (sea level anomaly in meters) illustrates with two 1:2 successively nested grids how the vortex smoothly propagates out of the refined grids.
