 C          after another in an un-pipelined fashion.

36    
37    C o Include pressure loading code
38    #define ATMOSPHERIC_LOADING
39    
40    C o exclude/allow external forcing-fields load
41    C   this allows to read & do simple linear time interpolation of oceanic
42    C   forcing fields, if no specific pkg (e.g., EXF) is used to compute them.
43    #undef EXCLUDE_FFIELDS_LOAD
44    
45    C o Include/exclude GM-like eddy stress in momentum code
46    #undef ALLOW_EDDYPSI
47    
48    C o Use "Exact Convervation" of fluid in Free-Surface formulation
49    C   so that d/dt(eta) is exactly equal to - Div.Transport
50    #define EXACT_CONSERV
51    
52    C o Allow the use of Non-Linear Free-Surface formulation
53    C   this implies that surface thickness (hFactors) vary with time
54    #undef NONLIN_FRSURF
55    
56    C o Allow mass source or sink of Fluid in the interior
57    C   (3-D generalisation of oceanic real-fresh water flux)
58    #undef ALLOW_ADDFLUID
59    
60    C o Choices for implicit solver routines solve_*diagonal.F
61    C   The following has low memory footprint, but not suitable for AD
62    #define SOLVE_DIAGONAL_LOWMEMORY
63    C   The following one suitable for AD but does not vectorize
64    #undef SOLVE_DIAGONAL_KINNER
65    
66    C o ALLOW isotropic scaling of harmonic and bi-harmonic terms when
67    C   using an locally isotropic spherical grid with (dlambda) x (dphi*cos(phi))
68    C *only for use on a lat-lon grid*
69    C   Setting this flag here affects both momentum and tracer equation unless
70    C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
71    C   The definition of the flag is commented to avoid interference with
72    C   such other header files.
73    C   The preferred method is specifying a value for viscAhGrid or viscA4Grid
74    C   in data which is then automatically scaled by the grid size;
75    C   the old method of specifying viscAh/viscA4 and this flag is provided
76    C   for completeness only (and for use with the adjoint).
77    C#define ISOTROPIC_COS_SCALING
78    
79    C o This flag selects the form of COSINE(lat) scaling of bi-harmonic term.
80    C *only for use on a lat-lon grid*
81    C   Has no effect if ISOTROPIC_COS_SCALING is undefined.
82    C   Has no effect on vector invariant momentum equations.
83    C   Setting this flag here affects both momentum and tracer equation unless
84    C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
85    C   The definition of the flag is commented to avoid interference with
86    C   such other header files.
87    C#define COSINEMETH_III
88    
89    C o Use "OLD" UV discretisation near boundaries (*not* recommended)
90    C   Note - only works with  #undef NO_SLIP_LATERAL  in calc_mom_rhs.F
91    C          because the old code did not have no-slip BCs
92    #undef  OLD_ADV_BCS
93    
94    C o Use LONG.bin, LATG.bin, etc., initialization for ini_curviliear_grid.F
95    C   Default is to use "new" grid files (OLD_GRID_IO undef) but OLD_GRID_IO
96    C   is still useful with, e.g., single-domain curvilinear configurations.
97    #undef OLD_GRID_IO
98    
99  C o Execution environment support options  C o Execution environment support options
100  #include "CPP_EEOPTIONS.h"  #include "CPP_EEOPTIONS.h"
101    
102    C o Include/exclude code specific to the ECCO/SEALION version.
103    C   AUTODIFF or EXF package.
104    C   Currently controled by a single header file
105    C   For this to work, PACKAGES_CONFIG.h needs to be included!
106    cph#if (defined (ALLOW_AUTODIFF) || \
107    cph     defined (ALLOW_ECCO) || \
108    cph     defined (ALLOW_EXF))
109    cph# include "ECCO_CPPOPTIONS.h"
110    cph#endif
111    
112    C o Allow full 3D specification of vertical diffusivity
113    #ifdef ALLOW_DIFFKR_CONTROL
114    C - Need to be defined if using DIFFKR_CONTROL
115    C   (alternatively, could have put this in ECCO_CPPOPTIONS)
116    #define ALLOW_3D_DIFFKR
117    #else
118    C - otherwise, can be turned on or off hereafter:
119    #undef  ALLOW_3D_DIFFKR
120    #endif /* ALLOW_DIFFKR_CONTROL */
121    
122    #endif /* CPP_OPTIONS_H */
