r2282 r2349 57 57 The specification of the space variation of the coefficient is made in 58 58 \mdl{ldftra} and \mdl{ldfdyn}, or more precisely in include files 59 \textit{ ldftra\_cNd.h90} and \textit{ldfdyn\_cNd.h90}, with N=1, 2 or 3.59 \textit{traldf\_cNd.h90} and \textit{dynldf\_cNd.h90}, with N=1, 2 or 3. 60 60 The user can modify these include files as he/she wishes. The way the 61 61 mixing coefficient are set in the reference version can be briefly described … … 63 63 64 64 \subsubsection{Constant Mixing Coefficients (default option)} 65 When none of the \textbf{key\_ ldfdyn\_...} and \textbf{key\_ldftra\_...} keys are65 When none of the \textbf{key\_dynldf\_...} and \textbf{key\_traldf\_...} keys are 66 66 defined, a constant value is used over the whole ocean for momentum and 67 67 tracers, which is specified through the \np{rn\_ahm0} and \np{rn\_aht0} namelist 68 68 parameters. 69 69 70 \subsubsection{Vertically varying Mixing Coefficients (\key{ ldftra\_c1d} and \key{ldfdyn\_c1d})}70 \subsubsection{Vertically varying Mixing Coefficients (\key{traldf\_c1d} and \key{dynldf\_c1d})} 71 71 The 1D option is only available when using the $z$-coordinate with full step. 72 72 Indeed in all the other types of vertical coordinate, the depth is a 3D function … … 77 77 and the transition takes place around z=300~m with a width of 300~m 78 78 ($i.e.$ both the depth and the width of the inflection point are set to 300~m). 79 This profile is hard coded in file \hf{ ldftra\_c1d}, but can be easily modified by users.80 81 \subsubsection{Horizontally Varying Mixing Coefficients (\key{ ldftra\_c2d} and \key{ldfdyn\_c2d})}79 This profile is hard coded in file \hf{traldf\_c1d}, but can be easily modified by users. 80 81 \subsubsection{Horizontally Varying Mixing Coefficients (\key{traldf\_c2d} and \key{dynldf\_c2d})} 82 82 By default the horizontal variation of the eddy coefficient depends on the local mesh 83 83 size and the type of operator used: … … 110 110 defined, see \hf{ldfdyn\_antarctic} and \hf{ldfdyn\_arctic}). 111 111 112 \subsubsection{Space Varying Mixing Coefficients (\key{ ldftra\_c3d} and \key{ldfdyn\_c3d})}112 \subsubsection{Space Varying Mixing Coefficients (\key{traldf\_c3d} and \key{dynldf\_c3d})} 113 113 114 114 The 3D space variation of the mixing coefficient is simply the combination of the … … 148 148 spurious diapycnal diffusion (see {\S\ref{LDF_slp}). 149 149 150 (4) when an eddy induced advection term is used (\key{tra hdf\_eiv}), $A^{eiv}$,150 (4) when an eddy induced advection term is used (\key{traldf\_eiv}), $A^{eiv}$, 151 151 the eddy induced coefficient has to be defined. Its space variations are controlled 152 152 by the same CPP variable as for the eddy diffusivity coefficient ($i.e.$
