It has given you the stack trace and even the line numbers (I think). Which field is get_data.f90 reading on line 125? What does it read after potential temperature climatology? Salt climatology perhaps? It's having trouble in get_cycle, which has to do with the time axis for said variable.

Have you considered trying again with a newer ROMS? Some of the I/O has changed since 3.2 so the bugs have changed too. In any case, a seg fault could be an array out of bounds, so I would recompile with bounds checking - just temporarily for figuring this out.

[ymamoutos]

Hi to everyone,

I've got "similar" problem.My ROMS version is 3.6. Kate you suggest to recompile with bounds checking. How can i do that?

Thanks for any help and for your time.

[kate]

It will depend on your compiler so you should ideally check its man pages. Mine says:

Debugging Options
-C Add array bounds checking; the same as -Mbounds.

It can give you info such as this:

Code: Select all

0: Subscript out of range for array a (tri_exchange_2d.f90: 501)
    subscript=42, lower bound=78, upper bound=123, dimension=1
0: Subscript out of range for array a (tri_exchange_2d.f90: 501)
    subscript=42, lower bound=118, upper bound=164, dimension=1

[ymamoutos]

Thanks for your advise Kate. My compiler is gfortran 4.4.3 and i used -fbounds-check flag.
The result for my current cpp definitions file (myapp.h) is:

Code: Select all

At line 74 of file get_data.f90
Fortran runtime error: Array reference out of bounds for array 'frc', upper bound of dimension 1 exceeded (1 > 0)

If i undefine the ANA_BSFLUX, ANA_BTFLUX, ANA_SMFLUX and ANA_STFLUX
because i don't use an external forcing file i get again runtime error for frc array:

Code: Select all

At line 2156 of file read_phypar.f90
Fortran runtime error: Array reference out of bounds for array 'frc', upper bound of dimension 1 exceeded (1 > 0)

Any suggestion/help would be appreciated. Thanks again for your time and your help.

Code: Select all

At line 74 of file get_data.f90
Fortran runtime error: Array reference out of bounds for array 'frc', upper bound of dimension 1 exceeded (1 > 0)

So this is with ANA_BSFLUX and friends? What is it trying to read on line 74 of get_data.f90?

If i undefine the ANA_BSFLUX, ANA_BTFLUX, ANA_SMFLUX and ANA_STFLUX
because i don't use an external forcing file i get again runtime error for frc array:

You want these all #defined, I believe. You need to provide a bottom salinity flux one way or another - most of us analytically set it to zero. Same for the rest, unless we're explicitly providing the surface fluxes.

[ymamoutos]

Kate hi,

on line 74 get_data.f90 calls subroutine get_2dfld for surface wind stress components.

You need to provide a bottom salinity flux one way or another - most of us analytically set it to zero.

So if am not providing an external file i have to modify ana_btflux.h and the other files if am understanding correct.

Thanks again for your patience and help.

[kate]

Yes, you have to set ANA_SMFLUX to tell it not to read surface momentum flux from a file. For these common ones, you can probably just leave it be the default of zero. If you aren't sure, you can read the analytical.f90 file to see what got picked up during the C preprocessor phase.

[ymamoutos]

Hi Kate and greetings from Greece,

My problem is solved.I modified the ana_*.h files
that i wanted for my test case following your suggestion
(i set the variables that i needed equal to zero) and
my model configuration is running smoothly until now.

Thanks again for your help and have a pleasant evening.
