================================

The option in red in cppdefs.h is missing in my "Activated C-preprocessing Options" and the options in red in my "Activated C-preprocessing Options" are missing in my cppdefs.h

And as I mentioned when I ran this setup with roms 3.0 the options worked as they should ...

How can that happen? What did I miss?

The key here is to look in the globaldefs.h file. There are chunks:

Code: Select all

#ifdef SOLVE3D
# if !(defined ADJOINT || defined TANGENT)
#   define VAR_RHO_2D
# endif
#endif
and

Code: Select all

#ifdef TS_U3ADV_SPLIT
# define DIFF_3DCOEF
# ifdef TS_U3HADVECTION
#  undef TS_U3HADVECTION
# endif
# ifndef TS_C4HADVECTION
#  define TS_C4HADVECTION
# endif
# ifndef TS_C4VADVECTION
#  define TS_C4VADVECTION
# endif
# ifndef TS_DIF4
#  define TS_DIF4
# endif
# ifdef TS_DIF2
#  undef TS_DIF2
# endif
# ifdef TS_SMAGORINSKY
#  undef TS_SMAGORINSKY
# endif
#endif
I wouldn't worry about the VAR_RHO bit. I don't understand why the second block was invoked, but maybe you can figure it out on your end.

Thanks Kate, good to know globaldefs.h does these kind of things. Im not sure how

Code: Select all

#ifdef TS_U3ADV_SPLIT
would prove positive (and that was the only define TS_C4VADVECTION part that I found) , but I did find the problem to be solved when I commented the diagnostics_uv line properly ...
