Re: one question about boundary condition in an idealized te

Thank you Kate! The boundary type for free surface I used before was 'Clamp'. If I understand right, the Flather type is for 2D momentum ubar/vbar. So I tested to use real ubar/vbar/uvel/vvel to be my boundary condition, with boundary type: Fla/ Fla/ Cla/ Cla. The initial u, v, ubar, vbar, zeta are ...

one question about boundary condition in an idealized test

Dear all, I am trying to run an idealized test, only having free surface as the boundary condition to drive the water current inside of my domain. The initial conditions are constant all over the domain: u0=0; v0=0; temp0=10; salt0=10; zeta0=0; However, I found that the simulated 'zeta' inside of my...

spatial discontinuity problem

Dear all, I am working on a case study of simulating the water current of estuary without wind forcing. The boundary condition and initial condition (including temperature, salinity, ubar, vbar, uvel, vvel, zeta) were interpolated from another hydrodynamic model simulation result. I have complete a ...

Re: Blowing up problem

Hi Kate,

Thanks for you reply! The minimum depth is the problem. I correct it to 2 meter instead and now ROMS is running!

Best regards

Blowing up problem

Dear all, I am working on a case study of simulation the water current of estuary without wind forcing. I have created my own model grid(by using GridBuilder), boundary and initial condition(by using ROMS matlab tool). The model blew up after 1st step. The standard output showing this: Basin informa...

Re: benchmark case compile problem

Hello, Check the timestamp on your oceanM or oceanG perhaps your build failed and the executable is an older one from an upwelling test case. Though I don't believe this is contributing to your issue, you might consider setting MY_PROJECT_DIR to ${PWD} so your executable is always written to the di...

Hello everyone, I am facing a problem when I tried to compile oceanM for benchmark case. I did get the executable file, oceanM, after running build script, attached below, but when I run it, I mentioned that the header file's name in the output log (attached below)was not right. It was "upwelli...

Re: Compile ROMS Error: Symbol 'eps' at (1) has no IMPLICIT

You didn't understand at all what I was saying to you, or what WET_DRY does. The wetting and drying option ( WET_DRY ) is modeled in ROMS by changing the associated land/sea masking arrays at every barotropic time-step in step2d , which affect the ocean state variables. The wet/dry mask is a new ar...

Re: Compile ROMS Error: Symbol 'eps' at (1) has no IMPLICIT

The WET_DRY option is not adjointed because it not fully differentiable, and because of every time-step of the forward trajectory need to be saved to have a consistent linearization of the tangent linear (TLM) and adjoint (ADM) models. You cannot use such time-depending land/sea masking in any ROMS...

Re: problem in test case of upwelling(mod_netcdf.f90)

-lm is a math library, not matlab. Maybe try putting your junk directory at the front of LD_LIBRARY_PATH instead. Thank you Kate, It seems the warning messages didn't bother me anymore. I found I didn't add the netcdf-fortran library folder into LD_LIBRARY_PATH, so I put netcdf and netcdf-fortran l...

Re: problem in test case of upwelling(mod_netcdf.f90)

My hdf libraries are a few years old but are version 10.0.x, but that probably has nothing to do with this at all. Do you get a linking error from NetCDF rather than HDF? Thanks for your reply, Kate! When I run oceanS, I did get a error message about netcdf: oceanS: error while loading shared libra...

Re: problem in test case of upwelling(mod_netcdf.f90)

Did you get a warning like that at the compile/linking phase too? It's probably missing the -lnetcdff in the link command.

i am not sure what you mean by a similar problem. How about we start over, and you explain the issue with as much information as you can. the last few lines of stdout saying "#0 0xFFFFFFFFFFFFFFFF" dont really tell me anything. so if you have something similar i would need to see the whol...

Re: compiling ROMS problem--ld: cannot find -lnetcdff

There are a couple oddities about your 'nf-config --flibs' output. First, "-O" and "-tp p7" are compiling flags, not linking flags. That would suggest that perhaps NetCDF wasn't configured/compiled quite right. Second, why is -R (I believe being treated as -rpath in this case) u...

Hi all Did anyone solve this problem in the end? I have a similar issue with coawstM, rather than oceanM, but I am guessing it is the same cause.
