6    
7    C CPP flags controlling particular source code features
8    
9    C o Shortwave heating as extra term in external_forcing.F
10    C Note: this should be a run-time option
11    #undef SHORTWAVE_HEATING
12    
13    C o Include/exclude phi_hyd calculation code
14    #define INCLUDE_PHIHYD_CALCULATION_CODE
15    
16    C o Include/exclude call to S/R CONVECT
17    #define INCLUDE_CONVECT_CALL
18    
19    C o Include/exclude call to S/R CALC_DIFFUSIVITY
20    #define INCLUDE_CALC_DIFFUSIVITY_CALL
21    
22    C o Allow latitudinally varying BryanLewis79 vertical diffusivity
23    #undef ALLOW_BL79_LAT_VARY
24    
25    C o Allow full 3D specification of vertical diffusivity
26    #undef ALLOW_3D_DIFFKR
27    
28    C o Include/exclude Implicit vertical advection code
29    #define INCLUDE_IMPLVERTADV_CODE
30    
31    C o Include/exclude AdamsBashforth-3rd-Order code
32    #undef ALLOW_ADAMSBASHFORTH_3
33    
34    C o Include/exclude nonHydrostatic code
35    #undef ALLOW_NONHYDROSTATIC
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 Use "Exact Convervation" of fluid in Free-Surface formulation
46    C   so that d/dt(eta) is exactly equal to - Div.Transport
47    #define EXACT_CONSERV
48    
49    C o Allow the use of Non-Linear Free-Surface formulation
50    C   this implies that surface thickness (hFactors) vary with time
51    #undef NONLIN_FRSURF
52    
53    C o ALLOW isotropic scaling of harmonic and bi-harmonic terms when
54    C   using an locally isotropic spherical grid with (dlambda) x (dphi*cos(phi))
55    C *only for use on a lat-lon grid*
56    C   Setting this flag here affects both momentum and tracer equation unless
57    C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
58    C   The definition of the flag is commented to avoid interference with
59    C   such other header files.
60    C   The preferred method is specifying a value for viscAhGrid or viscA4Grid
61    C   in data which is then automatically scaled by the grid size;
62    C   the old method of specifying viscAh/viscA4 and this flag is provided
63    C   for completeness only (and for use with the adjoint).
64    C#define ISOTROPIC_COS_SCALING
65    
66    C o This flag selects the form of COSINE(lat) scaling of bi-harmonic term.
67    C *only for use on a lat-lon grid*
68    C   Has no effect if ISOTROPIC_COS_SCALING is undefined.
69    C   Has no effect on vector invariant momentum equations.
70    C   Setting this flag here affects both momentum and tracer equation unless
71    C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
72    C   The definition of the flag is commented to avoid interference with
73    C   such other header files.
74    C#define COSINEMETH_III
75    
76    C o Use "OLD" UV discretisation near boundaries (*not* recommended)
77    C   Note - only works with  #undef NO_SLIP_LATERAL  in calc_mom_rhs.F
78    C          because the old code did not have no-slip BCs
79    #undef  OLD_ADV_BCS
80    
81    C o Use LONG.bin, LATG.bin, etc., initialization for ini_curviliear_grid.F
82    C   Default is to use "new" grid files (OLD_GRID_IO undef) but OLD_GRID_IO
83    C   is still useful with, e.g., single-domain curvilinear configurations.
84    #undef OLD_GRID_IO
85    
86    C o Execution environment support options
87    #include "CPP_EEOPTIONS.h"
88    
89    C o Include/exclude code specific to the ECCO/SEALION version.
90    C   AUTODIFF or EXF package.
91    C   Currently controled by a single header file
92    C   For this to work, PACKAGES_CONFIG.h needs to be included!
93    cph#if (defined (ALLOW_AUTODIFF) || \
94    cph     defined (ALLOW_ECCO) || \
95    cph     defined (ALLOW_EXF))
96    cph# include "ECCO_CPPOPTIONS.h"
97    cph#endif
