Ocean Modeling Discussion

Dear colleagues.
In the latest version of ROMS, sea ice module appeared in /ROMS/Nonlinear/SeaIce.

For successfully compile ROMS, it is necessary to define the following CPP options:
#define AVERAGES /* use if writing out NLM time-averaged data */
#define ICE_MODEL /* to activate sea-ice model ...

Which direction of vertical velocity is positive?

*.h, *.in and *.bash files are attached.

Dear Colleagues. Can anyone suggest what the problem might be.

When i use 60 proc or less, for example:
mpirun -np 60 romsM jes.in
it work well.

when i increase the number of processors, for example: mpirun -np 70 romsM jes.in
result is:
Program received signal SIGSEGV: Segmentation fault ...

During the work ROMS write the log file, but do not write restart and historical files.
-.in file is the follow:

i used ROMS/TOMS Framework: September 23, 2011
when i submit the job i reseived following:

no problem with initial and boundary conditions - all ini and bound data take from netcdf files
next massage after Courant numbers in log files:
