13     #define SEAICE_OPTIONS_H
14     #include "PACKAGES_CONFIG.h"
15     #include "CPP_OPTIONS.h"
16    
17     #ifdef ALLOW_SEAICE
18     C Package-specific Options & Macros go here
19    
20     C-- Write "text-plots" of certain fields in STDOUT for debugging.
21     #undef SEAICE_DEBUG
22    
23     C-- Allow sea-ice dynamic code.
24     C This option is provided to allow use of TAMC
25     C on the thermodynamics component of the code only.
26     C Sea-ice dynamics can also be turned off at runtime
27     C using variable SEAICEuseDYNAMICS.
28     #define SEAICE_ALLOW_DYNAMICS
29    
30     C-- By default, the sea-ice package uses its own integrated bulk
31     C formulae to compute fluxes (fu, fv, EmPmR, Qnet, and Qsw) over
32     C open-ocean. When this flag is set, these variables are computed
33     C in a separate external package, for example, pkg/exf, and then
34     C modified for sea-ice effects by pkg/seaice.
35     #define SEAICE_EXTERNAL_FLUXES
36    
37     C-- By default, the sea-ice package uses 2-category thermodynamics.
38     C When this flag is set, an 8-category calculation of ice
39     C thermodynamics is carried out in groatb.F
40     C Note the pickup_seaice.* generated by this option differ
41     C from those generated with the default 2-category model.
42     C Therefore it is not possible to switch between the two
43     C in the middle of an integration.
44     #undef SEAICE_MULTICATEGORY
45    
46     C-- Use the Old version of seaice_growth (close to cvs version 1.70)
47     C otherwise, use the merged version (with some of Ian Fenty s code)
48     #define SEAICE_GROWTH_LEGACY
49    
50     C-- Since the missing sublimation term is now included
51     C this flag is needed for backward compatibility
52     #undef SEAICE_DISABLE_SUBLIM
53    
54     C-- Suspected missing term in coupled ocn-ice heat budget (to be further tested)
55     #define SEAICE_DISABLE_HEATCONSFIX
56    
57     C-- options only available in the merged version
58     #ifndef SEAICE_GROWTH_LEGACY
59     C- to ensure heat conservation in the coupled ocean-seaice system
60     # undef SEAICE_HEAT_CONSERV_FIX
61     C- to preclude infinitesimal ice concentrations:
62     # undef ALLOW_PRECLUDE_INFINITESIMAL_AREA
63     #endif
64    
65     C-- By default sea ice is fresh. Set following flag for salty ice.
66     #undef SEAICE_VARIABLE_SALINITY
67    
68     C-- Tracers of ice and/or ice cover.
69     #undef ALLOW_SITRACER
70     #ifdef ALLOW_SITRACER
71     C-- To try avoid 'spontaneous generation' of tracer maxima by advdiff.
72     # define ALLOW_SITRACER_ADVCAP
73     #endif
74    
75     C-- By default the seaice model is discretized on a B-Grid (for
76     C historical reasons). Define the following flag to use a new
77     C (not thoroughly) test version on a C-grid
78     #define SEAICE_CGRID
79    
80     C-- Only for the C-grid version it is possible to
81     #ifdef SEAICE_CGRID
82     C enable EVP code by defining the following flag
83     # define SEAICE_ALLOW_EVP
84     # ifdef SEAICE_ALLOW_EVP
85     C-- When set use SEAICE_zetaMin and SEAICE_evpDampC to limit
86     C-- viscosities from below and above in seaice_evp
87     C-- not necessary, and not recommended
88     # undef SEAICE_ALLOW_CLIPZETA
89     # endif /* SEAICE_ALLOW_EVP */
90     C allow the truncated ellipse rheology (runtime flag SEAICEuseTEM)
91     # undef SEAICE_ALLOW_TEM
92     #else /* not SEAICE_CGRID, but old B-grid */
93     C-- By default for B-grid dynamics solver wind stress under sea-ice is
94     C set to the same value as it would be if there was no sea-ice.
95     C Define following CPP flag for B-grid ice-ocean stress coupling.
96     # define SEAICE_BICE_STRESS
97    
98     C-- By default for B-grid dynamics solver surface tilt is obtained
99     C indirectly via geostrophic velocities. Define following CPP
100     C in order to use ETAN instead.
101     # define EXPLICIT_SSH_SLOPE
102     C-- Defining this flag turns on a FV-discretization of the B-grid LSOR
103     C solver. It is smoother and includes all metric terms, similar to the
104     C C-grid solver. It is here for completeness, but its usefulness is
105     C unclear.
106     # undef SEAICE_LSRBNEW
107     #endif /* SEAICE_CGRID */
108    
109     C-- When set use MAX_HEFF to cap sea ice thickness in seaice_growth
110     #undef SEAICE_CAP_HEFF
111     C-- When set limit the Ice-Loading to mass of 1/5 of Surface ocean grid-box
112     #undef SEAICE_CAP_ICELOAD
113     C-- When set use SEAICE_clipVelocties = .true., to clip U/VICE at 40cm/s,
114     C-- not recommended
115     #undef SEAICE_ALLOW_CLIPVELS
116     C-- When set cap the sublimation latent heat flux in solve4temp
117     C according to the available amount of ice+snow. Otherwise this
118     C term is treated like all of the others -- residuals heat and
119     C fw stocks are passed to the ocean at the end of seaice_growth
120     C in a conservative manner. SEAICE_CAP_SUBLIM is not needed
121     C as of now, but kept just in case.
122     #undef SEAICE_CAP_SUBLIM
123    
124     C enable free drift code
125     #undef SEAICE_ALLOW_FREEDRIFT
126    
127     #endif /* ALLOW_SEAICE */
128     #endif /* SEAICE_OPTIONS_H */
