Ocean Modeling Discussion

Great thanks for offering the help. My office mate helps me finding the way to get the executable file working. I would like to post it here for people who may meet the same problem in the future. This is some conflicts between ROMS and setting of my institute cluster. It needs to change the Compile...

I tried parallel run first it showed the segmentation fault and then changed back to serial run, it shows the same problem. I turn off the debug. It shows the following information (./oceanS < ocean_upwelling.in) STEP Day HH:MM:SS KINETIC_ENRG POTEN_ENRG TOTAL_ENRG NET_VOLUME C => (i,j,k) Cu Cv Cw M...

The right input file is the ocean_upwelling.in, yes? I am sure I input it right and change the NtileI NtileJ to match cpu number I give to the machine. What else I need for a right input file?

Thanks Kate. I use linux + pgi fortran compiler. Could you let me know more about how to turn on the array-bounds? I never do that before.

I tried to search the segmentation fault on this Forum, but could not get a conclusion to solve the new ROMS 3.6 problem... Please help I installed ROMS 3.6 on our institute cluster and ran the upwelling as the test case. With the debug on, the program compiled, produced oceanG but with a warning at...

Dear Kate: Great thanks for the help. I copied the 2011-01-05 version ROMS Linux-pgi.mk to the Compilers Folder. The file can be compiled by the new makefile now. Two more little changes here: (1) the makefile line516: cp -p $(MAKE_MACROS) $(SCRATCH_DIR) It's not worked with -p option, when changed ...

I use netcdf 3.6.2. Do I have to use netcdf 4 for the new version? I use netcdf 3.6.2 for the 2011-01-05 version of ROMS. It still worked

No, this is not the case. I doubted about the problem either at the very beginning. So I double checked if there was a space after the include. Also, after I changed the netcdf directory, I clean the build file and make_marcos.mk. It produce a new build directory with netcdf.mod there. I doubted ROM...

I downloaded the newest version of ROMS (svn: $LastChangedRevision: 570 $) two days ago for my new project. I met the compiling problem at the very beginning when I tried to run the upwelling as a test. Looking for some helps for this problem. After I gave the right fortran compiler "pgi"...

I do not think a specific tracer is available for this type of requirements.

The Fennel Module has an oxygen component in. But it is a nitrogen-based model, and oxygen depends on the amount of nitrogen available.

What type of question you interested in?

Thanks for this reminder, I checked the program carefully today and found I made a stupid mistake: I did not point to the right directory when I compiled the file.

Thanks for help!

Yes, I did open the Diagnostic_TS. and Dout in the .in file

It still worked in the old way, only the Tname_hadv and Tname_vadv are output.

I am still working on it now

I installed new version of ROMS today to seperate the Tracer advection term in x and y direction (before only had Tname_hadv Tname_vadv). I opened the Diagnostic_TS in .h file, but it not worked. I

Is there anyone can help with this problem?

It seems the new version of ROMS has this function with u_xadv u_yadv
But I installed today. It seems no working. Is there anybody tried this with new ROMS and can help with this question?

Yes, I agree with what you said. I did not use the central finite difference as the model did. I believe the model is volume conserved. But if we select a small region and use Int(velocity x dArea). why usually we could not get a totally zero? Int(velocity x dArea) = Int(u*dydz) + Int(v*dxdz) + Int(...

I recently confused about mass conservation problem in ROMS.

I use the model output U,V,W on each grid, and calculated Pu/Px + Pv/Py + Pw/Pz problems on designed model grid. I could not get a completely zero on each grid. Can we get an idealized mass conservation from this way in calculation?

I'll have a new try. Thanks a lot.

Thank you for the reply, Kate. Sorry, I am a new beginner on the Linex system. Here I am a little confused about the conception about "the appropriate system". My NCL, gfortran and netcdf all could work sperately. Do they mean that they are already for the appropriate system.

Hi: I tried to install ROMS plot package on my MAC OX 10.4.11 machine. My fortran complier is GNU gfortran. Since the ./Compilers/ do not have Darwin-gfortran.mk, I copy the Linex-gfortran.mk to Darwin-gfortran.mk. Then I tried make. It report a problem as follows: /usr/bin/ld: warning -L: directory...

I see, thanks a lot for the answering.

I was expected an instantaneous diagnostics. Actually, I am using the biological/physical coupled model. I am interested in the physical advection/transportation competing with those biological source/sinks in week or month scale. Currently, my model was forced by a 1 hour time interval wind and the...

Hi: I am trying to do some mass balance analysis for some tracer that I interested in. I hope I could get a continues time-series for advection and diffusion term at a certain location. I think station would help. But when I set up the stations.in file it seems it can only record those tracers value...

Thanks a lot for the soon reply. I'll just move and change the name right now.

I met a problem when I tried to use the "restart" function of ROMS3.0. I hope my data could append to the existing "HIS" and "DIA" file . But it never happens, I have set NRREC > 0 and LDEFOUT = F. Here is a detail: My time step was by minutes, and I wrote the records ...
