Re: can't write to average file after restarted

I had this problem some time ago. Have erased the files since then, so don't remember all the details. But I seem to recall that this was only a problem when I used the PERFECT_RESTART cpp option. I was able to keep going by not activating this option (albeit with less than perfect restart condition...

Re: Perfect restart problem for large grid

Thanks for the reply Kate,

We're using netcdf 3.6.2, so I don't think this should be a problem. When running without PERFECT_RESTART other .nc files (_his, _avg) become much larger than 2GB (_rst stays below 2GB though).

Perfect restart problem for large grid

We've encountered a problem when using PERFECT_RESTART. The model complains upon start-up for a setup where the grid is rather large (1022x0578x032). The console output ends with: STEP time[DAYS] KINETIC_ENRG POTEN_ENRG TOTAL_ENRG NET_VOLUME trd 0 0.00000 1.580116E-03 1.251719E+04 1.251719E+04 9.014...

Scientist position at the Norwegian Met. Institute

The Norwegian Meteorological Institute (http://met.no) has a vacant permanent position as scientist in the oceanography section of the R&D department in Oslo. Work with data assimilation techniques in ocean circulation models (particularly ROMS) will be a core activity. Details are available from ht...

River direction (Dsrc)

This is not really a bug, but perhaps an inconsistency between the code and comments describing the code: In mod_sources.F it is stated that the direction of rivers (SOURCES % Dsrc) should be zero for river flow along the xi-direction and larger than zero for flow along the eta-direction. And in pre...

Diapycnal mixing

I notice ROMS offers the option of 'horizontal' diffusion of T and S along constant rho surfaces, i.e. what I would (somewhat sloppily?) call 'isopycnal' mixing. Is there a way to operate with mixing across rho surfaces, i.e. 'diapycnal' mixing (instead of vertical mixing)?

Tnx, Paal Erik

MPI blow up for east-west periodic boundary conditions

Hi. I'm attempting some runs with east-west periodic boundary conditions. The model works fine in serial mode (on an Alpha) but blows up imediately in MPI mode (SGI). The relevant (I believe) cpp options used are: #undef EASTERN_WALL #undef WESTERN_WALL #define EW_PERIODIC #define SOUTHERN_WALL #def...
