    20 Compile test cases 
    21 ------------------ 
    22  
    23 The compilation of the test cases is very similar to the manner the reference configurations are compiled. 
    24 If you are not familiar on how to compile NEMO, it is first recomended to read :doc:`the instructions <install>` 
    25  
    26 | In the same manner as the ref. cfg are compiled with '-r' option, test cases can be compile by the use of makenemo with '-a' option. 
    27 | Here an example to compile a copy named WAD2 of the wetting and drying test case (WAD) on the macport_osx architecture on 4 cores:

    4256ICE_AGRIF 
    43 ========= 
    44    
    45   This test case illustrates the advection of an ice patch across an East/West and North/South periodic channel 
    46   over a slab ocean (i.e. one ocean layer), and with an AGRIF zoom (1:3) in the center 
    47   The purpose of this configuration is to test the advection of the ice patch in   
    48   and across the AGRIF boundary 
    49   One can either impose ice velocities or ice-atm. stresses and let rheology define velocities 
    50   (see README for details)

    5473VORTEX 
    55 ====== 
    56    
    57   This test case illustrates the propagation of an anticyclonic eddy over a Beta plan and a flat bottom. 
    58   It is implemented here with an online refined subdomain (1:3) out of which the vortex propagates. 
    59   It serves as a benchmark for quantitative estimates of nesting errors as in Debreu et al. (2012) :cite:`DEBREU2012`, 
    60   Penven et al. (2006) :cite:`PENVEN2006` or Spall and Holland (1991) :cite:`SPALL1991`. 
    61    
    62   The animation below (sea level anomaly in meters) illustrates with two 1:2 successively nested grids how 
    63   the vortex smoothly propagates out of the refined grids.

    68 ====== 
    69  
    70   The purpose of this test case is to evaluate the impact of various schemes and new development with the iceshelf cavities circulation and melt. 
    71   This configuration served as initial assesment of the ice shelf module in Losh et al. (2008) :cite:`LOSCH2008` and Mathiot et al. (2017) :cite:`MATHIOT2017`.  
    72   The default setup is the one described `here <http://staff.acecrc.org.au/~bkgalton/ISOMIP/test_cavities.pdf>`_.

    81   The LOCK EXCHANGE experiment is a classical fluid dynamics experiment that has been adapted 
    82   by Haidvogel and Beckmann (1999) :cite:`HAIDVOGEL1999` for testing advection schemes in ocean circulation models. 
    83   It has been used by several authors including Burchard and Bolding (2002) :cite:`BURCHARD2002` and Ilicak et al. (2012) :cite:`ILICAK2012`. 
    84   The LOCK EXCHANGE experiment can in particular illustrate the impact of different choices of numerical schemes  
    85   and/or subgrid closures on spurious interior mixing.

    96   The OVERFLOW experiment is adapted from the non-rotating overflow configuration described  
    97   in Haidvogel and Beckmann (1999) :cite:`HAIDVOGEL1999` and further used by Ilicak et al. (2012) :cite:`ILICAK2012`.

    104145WAD 
    105 === 
    106  
    107   A set of simple closed basin geometries for testing the Wetting and drying capabilities.  
    108   Examples range from a closed channel with EW linear bottom slope to a parabolic EW channel with a Gaussian ridge. 
    109    
    110   Below the animation of the test case 7. This test case is a simple linear slope with a mid-depth shelf with an open boundary forced with a sinusoidally varying ssh. 
    111   This test case has been introduced to emulate a typical coastal application with a tidally forced open boundary with an adverse SSH gradient that, when released, creates a surge up the slope. 
    112   The parameters are chosen such that the surge rises above sea-level before falling back and oscillating towards an equilibrium position
