New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

New LaTeX commands \nam and \np to mention namelist content (step 2)
So far so good, the manual compiles successfully 4 times and everything seems in its right place

    327327A key point in \autoref{eq:DYN_een_e3f} is how the averaging in the \textbf{i}- and \textbf{j}- directions is made. 
    328328It uses the sum of masked t-point vertical scale factor divided either by the sum of the four t-point masks 
    329 (\np{nn_een_e3f}{nn\_een\_e3f}\forcode{=1}), or just by $4$ (\np{nn\_een\_e3f}\forcode{=.true.}). 
     329(\np{nn_een_e3f}{nn\_een\_e3f}\forcode{=1}), or just by $4$ (\np{nn_een_e3f}{nn\_een\_e3f}\forcode{=.true.}). 
    330330The latter case preserves the continuity of $e_{3f}$ when one or more of the neighbouring $e_{3t}$ tends to zero and 
    331331extends by continuity the value of $e_{3f}$ into the land areas. 
     
    904904    In this particular exemple, 
    905905    a boxcar averaging window over \np{nn_baro}{nn\_baro} barotropic time steps is used 
    906     (\np{nn\_bt\_flt}\forcode{=1}) and \np{nn_baro}{nn\_baro}\forcode{=5}. 
     906    (\np{nn_bt_flt}{nn\_bt\_flt}\forcode{=1}) and \np{nn_baro}{nn\_baro}\forcode{=5}. 
    907907    Internal mode time steps (which are also the model time steps) are denoted by 
    908908    $t-\rdt$, $t$ and $t+\rdt$.

    12681268The large vertical diffusion coefficient found in the surface mixed layer together with high vertical resolution implies that in the case of explicit time stepping there would be too restrictive a constraint on the time step. 
    12691269Two time stepping schemes can be used for the vertical diffusion term: 
     
    14091409flux is from a cell with water depth greater than \np{rn_wdmin1}{rn\_wdmin1} and 0 otherwise. If the user sets 
    14101410\np{ln_wd_dl_ramp}{ln\_wd\_dl\_ramp}\forcode{=.true.} the flux across the face is ramped down as the water depth decreases 
    1411 from 2 * \np{rn_wdmin1}{rn\_wdmin1} to \np{rn\_wdmin1}. The use of this ramp reduced grid-scale noise in idealised test cases.

    16521652The general framework for dynamics time stepping is a leap-frog scheme,
