Issue restarting solutions in fraction of a day

Hi All, I've recently bumped into an issue when restarting forecast simulations that run 2x daily, e.g. when restart files have the first time record at a fraction of a day (12 h, for example). I've tracked it down and found a possible typo on dateclock.F 430:436, as below. ! ! Fractional date numbe...

Re: Error of installing PyCNAL on conda

I still happily use pyroms as well. I can see the advantages of making something work across different models. I think it's an interesting balance. You have to make the abstractions more generic and might not be able to fully map each model objects into one library, what will eventually result in st...

Re: Docker container for ROMS?

Docker is a very lightweight form of virtualization if the host OS is Linux. In our experience, there is no detectable loss of performance. If your host OS is MacOS or Windows, docker will add a virtual machine as an abstract layer in between, then you have performance loss.

Re: Is there a balance between SSH and currents?

I think bathymetry is one thing to look at. Inaccurate bathy can cause discrepancies in tidal elevations. Note that under or over estimation of real depth in remote areas can also affect the local sea level due to effects in the tidal wave propagation. Might worth sanity-checking or accuracy-checkin...

New python GUI tools for ROMS

Hi all, I've been working on two python GUI's to support visualization of inputs/outputs and land mask editing in ROMS. They are both inspired on editmask and romsgui from the ROMSTOOLS ( http://www.romsagrif.org/ ), but works for the most current official ROMS versions at http://myroms.org/ . I tho...

Re: need help interpreting erroneous ROMS results

What type of open boundary conditions are you using? With which variables and with which frequency are you feeding your boundaries? Using Volcons? Could you post your ocean.in and a log file from the simulation so we can have a better idea of your configs?

Re: DT and NDTFAST trouble

Did you try to increase the stack limit in the machine you're running? Just a guess, but since you decreased the time step, there is more memory being used in between netcdf time records.

Are you familiar with the https://www.docker.com/ approach? It could be a good alternative to virtual machines, because they are super light, actually seamless when running in the same OS host.

Re: sponge width

I don't know if there are any rules of thumb for this, but I generally define the sponge layer size based on the horizontal scale of the dominant phenomena I'm interested in, following what is suggested in Marchesiello et al. (2001)-Oc.Mod.

Re: Typos

Hi,

I was browsing on wikiroms User Guide > Source Code > Functionals section and I think I found a typo regarding ana_hmixcoef.h. It says "For providing analytic atmospheric cloud fraction." in spite of something related to horizontal mixing.
