Re: ROMS kinetic energy and other problems

Below are the CPP options that I used for the 2004 Global Roms, but 1st let me suggest a perhaps easier alternative for your southern boundary. Why not extending your southern bdry to Antarctica and using EW_PERIODIC in the east-west direction for the ACC? that has been sucessfully done in the past ...

Re: ROMS kinetic energy and other problems

I found an old hard drive where I **might** have the original cpp.h file. I will post/send it later tonight. Your cpp.h has some non-standard choices. Are you using tidal forcing?

Re: ROMS Global Solution

For a Pacific domain, 3-4 years should be enough to get the main features of the upper 400-500 m of the ocean. Could you upload some figures? but not here (i.e., ROMS Results), open a new topic in "ROMS Problems" instead. Guillermo.

Re: Can VISC2 be scaled by depth?

BAN, you will need to do some coding but technically, I don't see why it wouldn't be possible. I envision 2 ways, a) one is by modifiying the code where Hernan dealt with the variable grid size and viscosity, and perhaps importing the bottom topography if that variable is not currently included in t...

Re: Rivers/Sinks

Thank you Kate,

I haven't read anywhere that the source/sink needs to be against the wall/coastline. I need to place a source/sink in the open i.e., with neighboring grid cells being all wet ones. thx once more.

when defining UV_Psource, what parameter defines if it's a source or a sink? the sign of the vertically mass transport? positive for rivers, negative for sinks?

I don't have "Intel Mpi". Do I need it to compile ROMS, or the libraries contained in ROMS/LIBS/MCT should do the job?

Any other tips related to mpi compilation with the Intel compiler are more than welcome :wink:

Re

got it.

If one uses the PG linux86 compiler (on the opteron server) you get similar results but not quite what it should be.

So, things worked when I compiled with the PG linux86-64 compiler (opteron is 32-64bit).

When using a variable-resolution grid, ROMS offers the advantage of making the viscosity (and diffusivity) coefficients proportional to the grid size (user specifies coefficient for the coarsest grid point, then by %define VISC_GRID in cppdefs.h, ROMS computes the visc coeff for the rest of the gri...
