postdoc in larval transport at Rutgers

We invite applications for a Postdoctoral Associate to investigate how waves, turbulence, and flow-induced larval behavior affect larval transport in the Middle Atlantic Bight and adjacent estuaries. Waves and turbulence induce behavioral responses that alter larval vertical distributions and may en...

Re: Anomalous Land Points in LTRANS

I am just starting a new LTRANS setup and have encountered the same problem. I haven't dug too far into it yet. Did you identify the cause?

(u,v)_visc not writing to diagnostics file

Using revision 467 I found that the diagnostics were not writing the vertical velocity terms. It looks like this is due to missing code in inp_par.F. I have added lines at 2767 that seem to have fixed this. ELSE IF (TRIM(KeyWord).eq.'Dout(M3vvis)') THEN IF (M3vvis.le.0) THEN IF (Master) WRITE (out,2...

Re: Kantha_Clayson mixed layer method and wave model

I would guess that most of us who use GLS use the Kantha and Clayson stability functions. The two-equation models in GLS require two choices: 1) choose a length-scale model (the numbers in ocean.in). 2) choose a stability function (choose in cppdefs). John Warner's 2005 paper (Ocean Modelling, 8, 81...

Re: Problems running re-start solutions.

Alex, I've had a nearly identical problem recently. I would run a model for two weeks. Then use perfect restart to run for a few days more. I was only using PGI. When I optimized at level 3 (or 2) it blew up (sometimes it would go through a couple time-steps, I believe). When I optimize at level 1 i...

Re: Vertical mixing scheme in ROMS

Peter,

I have had trouble with k-epsilon being a bit less stable than the other closure schemes. Reducing the time step has helped fix this. Not an entirely satisfactory solution, I know.

Re: GLS y MY25 in ROMS

The mixing schemes are in gls_corstep.F and my25corstep.F, which are in the Nonlinear directory of your source code. You can get the essential features of Mellor-Yamada by choosing kkl in GLS.

Re: Vertical tracer advection

Kate--

What settings are you using for GLS? I have found k-epsilon to be less stable than the other versions. Did you try k-omega or gen?

Re: problem compiling with FLOATS

Thanks for checking that.
I get the same error with version 297.
I'll dig deeper into my files.

Re: problem compiling with FLOATS

Thanks.
FLT_TEST compiles without SOLVE3D, but not with SOLVE3D.
Does it work both ways for you? It doesn't seem to depend on the version I am using.

problem compiling with FLOATS

I am trying to run a simulation with the cpp option FLOATS, and I get a compilation error. Has anyone else encountered this? This is my first time with FLOATS. Are there other cpp options that I should be using? I am using revision 291. The error messages are: PGF90-S-0038-Symbol, flt_lagran, has no...

Re: meet trouble with GLS_MIXING

I found the same thing as jacopo. Reducing the time step made it run fine.
Have you tested it with all three stability functions (Kantha-Clayson, Canuto A and Canuto B?)
