Just to verify, you've set it up to run in parallel, right? (v.s. serial runs on different nodes).
Thanks for the feedback!

Experience with parallel ROMS on Mac Pro?
I'm wondering if anyone has experience installing ROMS on a Mac Pro (4-12 core) for parallel processing? Are there any problems that one should be aware of before considering a Mac Pro for this application?

Hi again,
Good point by you, re: the 2D bit. I will be interested to hear what you discover.

Re: Results and issues of barotropic tidal run
How about bathymetry? Have you compared your ROMS model bathymetry to the actual values at the ADCP locations? Has smoothing (to meet Haney/rx0 criterion) altered the bathymetry in this location by an appreciable amount?

Re: Lagrangean labels or dye with no mixing
Hi Rodrigo, I am not familiar with the use of passive tracers as a dense mass of Lagrangian floats, but my experience with using passive tracers would advise against it. I could be wrong, but you may want to consider floats instead. In my application, an instability in the passive tracer caused the ...

Re: troubleshooting open boundary problem
I keep forgetting to post the solution, so--before too much time goes by--here it goes.... The problem that I described above was caused by 0m water depth in the mask region, which resulted in -dZ under land mask. This -dZ was not a problem for the closed boundary or gradient boundary conditions. It...

troubleshooting open boundary problem
I am having a hard time figuring out why my open boundary run doesn't run in ROMS 3.2. When I say "doesn't run", I mean that it blows up at first time step. Here is what works: 1) closed boundaries 2) open boundary on the east (closed N,S,W). East is only open water. 3) open boundaries wit...

Hi Diego, Another potential contribution is the 'angle' parameter. I see a note in a previous post about adding the scalar value of 'angle' to the output, but no mention of the 'angle' array (unless I missed it elsewhere?). I borrowed some code from the seagrid routine to come up with the following....

Re: EASYGRID: Grid generation for ROMS
Bug found, captured, and made into butterfly.
I believe the smth_bath call in easygrid should be as follows:
h = smth_bath(h,mask_rho, order, rlim, npass);
instead of
h = smth_bath(h,mask_rho);
The later works, it simply applies the default values every time.
Cheers,
Rachael

Southern Hemisphere Kelvin
Good idea to describe the more general case that I was conveniently avoiding. :-) I'm working in the southern hemisphere too and had to convince myself of the signs. My coast is also aligned N-S rather than E-W (hence, u=0). The full expression for my case is a simplified version of: v = eta_0 * sqr...

Hi me, The way I fixed this (thanks to Susan H.!) was to 1) added #define ANA_SRFLUX in CPPDEFS.h file 2) changed the "j" to "i" index in the analytical. F file. I made other changes to the indices too, but those were different kinds of bugs than I was reporting here. Unfortunate...

clarification on KELVIN case fix
Thanks for the commentary Kevin. Just to prevent further confusion in interpreting your representation and my earlier comment, the equation can be written in two ways: U = Uo*exp(-f*y/c)*cos(omega*time), for f>0 where Uo = c*eta_0/H, c = sqrt(g*H) OR Uo = eta_0*sqrt(g/H) I think there may be another...

Kelvin wave bug
Thanks for mentioning this Alexander. The dimensions actually do work out because the equation I posted is incomplete. There is an amplitude scaling in the code that provides the 'm' dimension. I really should have written: U = eta_o * sqrt(g/H) * exp(-f*y/sqrt(g*H))*cos(omega*time), for f>0 In the ...

KELVIN case typo
This may be fixed in ROMS 3.X, but there is a bug in the KELVIN case for ROMS 2.2. The Kelvin wave solution should be of the form U = sqrt(g/H)*exp(-f*y/sqrt(g*H))*cos(omega*time). The KELVIN case in Analytical.F file has the form of: U = sqrt(g/H)*exp(-f*y/sqrt(g/H))*cos(omega*time). I'm still a ne...

Hello everyone, Yes--I know--2.2. :? I have plans to upgrade to 3.1 later this summer, I promise.

Or go to John Hunter's home page and look for "ISOMIP" files.

I am looking for a good reference on the equations used in the ROMS ice shelf coupling, but I am obviously not looking in the right places.
