1  C $Header$  C $Header$
2  C  C $Name$
3    
4  C This enables the C-D grid method of integrating the Coriolis terms  #ifndef CPP_OPTIONS_H
5  #define ALLOW_CD  #define CPP_OPTIONS_H
6    
7  C This enables use of the diagnostics packages  C CPP flags controlling particular source code features
 #define ALLOW_DIAGNOSTICS  
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 full 3D specification of vertical diffusivity
23    #undef ALLOW_3D_DIFFKR
24    
25    C o Include/exclude Implicit vertical advection code
26    #define INCLUDE_IMPLVERTADV_CODE
27    
28    C o Include/exclude AdamsBashforth-3rd-Order code
29    #undef ALLOW_ADAMSBASHFORTH_3
30    
31    C o Include/exclude nonHydrostatic code
32    #undef ALLOW_NONHYDROSTATIC
33    
34    C o Include pressure loading code
35    #define ATMOSPHERIC_LOADING
36    
37    C o Use "Exact Convervation" of fluid in Free-Surface formulation
38    C   so that d/dt(eta) is exactly equal to - Div.Transport
39    #define EXACT_CONSERV
40    
41    C o Allow the use of Non-Linear Free-Surface formulation
42    C   this implies that surface thickness (hFactors) vary with time
43    #undef NONLIN_FRSURF
44    
45    C o ALLOW isotropic scaling of harmonic and bi-harmonic terms when
46    C   using an locally isotropic spherical grid with (dlambda) x (dphi*cos(phi))
47    C *only for use on a lat-lon grid*
48    C   Setting this flag here affects both momentum and tracer equation unless
49    C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
50    C   The definition of the flag is commented to avoid interference with
51    C   such other header files.
52    C   The preferred method is specifying a value for viscAhGrid or viscA4Grid
53    C   in data which is then automatically scaled by the grid size;
54    C   the old method of specifying viscAh/viscA4 and this flag is provided
55    C   for completeness only (and for use with the adjoint).
56    C#define ISOTROPIC_COS_SCALING
57    
58    C o This flag selects the form of COSINE(lat) scaling of bi-harmonic term.
59    C *only for use on a lat-lon grid*
60    C   Has no effect if ISOTROPIC_COS_SCALING is undefined.
61    C   Has no effect on vector invariant momentum equations.
62    C   Setting this flag here affects both momentum and tracer equation unless
63    C   it is set/unset again in other header fields (e.g., GAD_OPTIONS.h).
64    C   The definition of the flag is commented to avoid interference with
65    C   such other header files.
66    C#define COSINEMETH_III
67    
68    C o Use "OLD" UV discretisation near boundaries (*not* recommended)
69    C   Note - only works with  #undef NO_SLIP_LATERAL  in calc_mom_rhs.F
70    C          because the old code did not have no-slip BCs
71    #undef  OLD_ADV_BCS
72    
73    C o Use LONG.bin, LATG.bin, etc., initialization for ini_curviliear_grid.F
74    C   Default is to use "new" grid files (OLD_GRID_IO undef) but OLD_GRID_IO
75    C   is still useful with, e.g., single-domain curvilinear configurations.
76    #undef OLD_GRID_IO
77    
78    C o Execution environment support options
79  #include "CPP_EEOPTIONS.h"  #include "CPP_EEOPTIONS.h"
80    
81    C o Include/exclude code specific to the ECCO/SEALION version.
82    C   AUTODIFF or EXF package.
83    C   Currently controled by a single header file
84    C   For this to work, PACKAGES_CONFIG.h needs to be included!
85    cph#if (defined (ALLOW_AUTODIFF) || \
86    cph     defined (ALLOW_ECCO) || \
87    cph     defined (ALLOW_EXF))
88    cph# include "ECCO_CPPOPTIONS.h"
89    cph#endif
90    
91    #endif /* CPP_OPTIONS_H */
