    1010=== Description === 
    11 Add diagnostics of the maximum CFL number into NEMO. 
     11Add a module to calculate and output the maximum CFL number during a model run. This can be used to inform users if they are close to exceeding CFL stability criterion. 
     12 
     13The code exists in a local branch at NEMO3.4 and minimal changes should be required to implement this in the latest NEMO version. 
     14 
     15The changes will consist of adding one new module and a single call to it in step.F90. The output is written to an ascii file.

    1317---- 
    1418=== Testing === 
    15 Testing could consider (where appropriate) other configurations in addition to NVTK]. 
     19The code will be SETTE tested. 
     20A short (few time step simulation) will be run with timestep level output. The CFL calculations can then be checked offline using python code.
