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 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 exclude/allow external forcing-fields load |
| 38 |
C this allows to read & do simple linear time interpolation of oceanic |
| 39 |
C forcing fields, if no specific pkg (e.g., EXF) is used to compute them. |
| 40 |
#undef EXCLUDE_FFIELDS_LOAD |
| 41 |
|
| 42 |
C o Include/exclude GM-like eddy stress in momentum code |
| 43 |
#undef ALLOW_EDDYPSI |
| 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 |
#define NONLIN_FRSURF |
| 52 |
|
| 53 |
C o Allow mass source or sink of Fluid in the interior |
| 54 |
C (3-D generalisation of oceanic real-fresh water flux) |
| 55 |
#define ALLOW_ADDFLUID |
| 56 |
|
| 57 |
C o ALLOW isotropic scaling of harmonic and bi-harmonic terms when |
| 58 |
C using an locally isotropic spherical grid with (dlambda) x (dphi*cos(phi)) |
| 59 |
C *only for use on a lat-lon grid* |
| 60 |
C Setting this flag here affects both momentum and tracer equation unless |
| 61 |
C it is set/unset again in other header fields (e.g., GAD_OPTIONS.h). |
| 62 |
C The definition of the flag is commented to avoid interference with |
| 63 |
C such other header files. |
| 64 |
C The preferred method is specifying a value for viscAhGrid or viscA4Grid |
| 65 |
C in data which is then automatically scaled by the grid size; |
| 66 |
C the old method of specifying viscAh/viscA4 and this flag is provided |
| 67 |
C for completeness only (and for use with the adjoint). |
| 68 |
C#define ISOTROPIC_COS_SCALING |
| 69 |
|
| 70 |
C o This flag selects the form of COSINE(lat) scaling of bi-harmonic term. |
| 71 |
C *only for use on a lat-lon grid* |
| 72 |
C Has no effect if ISOTROPIC_COS_SCALING is undefined. |
| 73 |
C Has no effect on vector invariant momentum equations. |
| 74 |
C Setting this flag here affects both momentum and tracer equation unless |
| 75 |
C it is set/unset again in other header fields (e.g., GAD_OPTIONS.h). |
| 76 |
C The definition of the flag is commented to avoid interference with |
| 77 |
C such other header files. |
| 78 |
C#define COSINEMETH_III |
| 79 |
|
| 80 |
C o Use "OLD" UV discretisation near boundaries (*not* recommended) |
| 81 |
C Note - only works with #undef NO_SLIP_LATERAL in calc_mom_rhs.F |
| 82 |
C because the old code did not have no-slip BCs |
| 83 |
#undef OLD_ADV_BCS |
| 84 |
|
| 85 |
C o Use LONG.bin, LATG.bin, etc., initialization for ini_curviliear_grid.F |
| 86 |
C Default is to use "new" grid files (OLD_GRID_IO undef) but OLD_GRID_IO |
| 87 |
C is still useful with, e.g., single-domain curvilinear configurations. |
| 88 |
#undef OLD_GRID_IO |
| 89 |
|
| 90 |
C o Execution environment support options |
| 91 |
#include "CPP_EEOPTIONS.h" |
| 92 |
|
| 93 |
C o Include/exclude code specific to the ECCO/SEALION version. |
| 94 |
C AUTODIFF or EXF package. |
| 95 |
C Currently controled by a single header file |
| 96 |
C For this to work, PACKAGES_CONFIG.h needs to be included! |

C o Allow full 3D specification of vertical diffusivity |
| 104 |
#ifdef ALLOW_DIFFKR_CONTROL |
| 105 |
C - Need to be defined if using DIFFKR_CONTROL |
| 106 |
C (alternatively, could have put this in ECCO_CPPOPTIONS) |
| 107 |
#define ALLOW_3D_DIFFKR |
| 108 |
#else |
| 109 |
C - otherwise, can be turned on or off hereafter: |
