The code I have calls it UV_VIS2, not VISC2. Asking for a flag ROMS doesn't know about is like asking for #define MARS, not going to do anything. Which ROMS are you using?

What advection scheme are you using? There's this block in globaldefs.h:

Code: Select all

#ifdef UV_U3ADV_SPLIT
# define VISC_3DCOEF
# ifndef UV_C4ADVECTION
#  define UV_C4ADVECTION
# endif
# ifndef UV_VIS4
#  define UV_VIS4
# endif
# ifdef UV_VIS2
#  undef UV_VIS2
# endif
# ifdef UV_SMAGORINSKY
#  undef UV_SMAGORINSKY
# endif
#endif
