10    C !DESCRIPTION:
11    C Contains CPP macros/flags for controlling optional features of package.
12    CEOP
13    
14    C CPP options file for GAD (Generic Advection Diffusion) package
15    C
16    C Use this file for selecting options within the GAD package
17    C
18    C GAD is enabled with ALLOW_GAD in CPP_OPTIONS.h

22    #ifndef __GAD_OPTIONS
23    #ifndef DISABLE_GENERIC_ADVDIFF

25    C The selects the form of COSINE(lat) scaling of bi-harmonic term.
26    C *only for use on a lat-lon grid*
27    #define COSINEMETH_III
28    
29    C The selects isotropic scaling of bi-harmonic term when
30    C using the COSINE(lat) scaling.
31    #undef  ISOTROPIC_COS_SCALING
32    
33    C As of checkpoint41, the inclusion of multi-dimensional advection
34    C introduces excessive recomputation/storage for the adjoint.
35    C We can disable it here using CPP because run-time flags are insufficient.
36    #define  DISABLE_MULTIDIM_ADVECTION
37    
38    #else
39    
40    C If GAD is disabled then so is multi-dimensional advection
41    #define DISABLE_MULTIDIM_ADVECTION
42    
43    #endif /* DISABLE_GENERIC_ADVDIFF */
44    #define __GAD_OPTIONS
45    #endif /* __GAD_OPTIONS */
