Ocean Modeling Discussion

hello everyone In recent day，I have run a case using the COAWST model in serial mode. ALL the input files have no problems. But when it ran for a one-day, it stoped in the 00:00 of the second day and reported a Segmentation fault(core dumped). 284 2010-01-01 23:40:00.00 2.207029E-03 2.168432E+04 2.1 ...

I think you are barking up the wrong tree. it is most likely not an mpi issue. Now that you changed to mpich you need to make sure that the mpirun call points to mpich, and that all the libraries (hdf5, netcdf ,etc ...) are all with that flavor of mpi. Suggest you go back to openmpi and fix the ...

hello everyone I use the COAWST model （so far,only use the ROMS）to simulate sediment transport. Before this, I successfully run the several cases in the project. But when I run the real case in caowstM, the output.log report the error below: NLM: GET_STATE - Reading state initial conditions, 2010-01- ...

it is not that big of an effort. Just do a diff of your ocean.in to lets say the Sandy ocean.in. that is all. It will probably not be the issue. Suggest you compile in debug mode, and run that. hello john I follow your idea and run it in debug mode. However, weird things happen: when I run in ...

not sure. if you are using COAWST, make sure you start with a COAWST ocean input file. Compare yours to the one in Inlet Test or Sandy or something like that. We have a few differences to Rutgers, such as NBCfiles and NCLmfiles, etc. Another thing to try is to compile in debug=on and that gives a ...

good that you are making progress. but at this point, there is not much information there to help. look through that entire log file, are there any NaN's? does the data look correct? use ncview or ncdump or matlab or anything to look at the fields in your "mycase-ini.nc" file. maybe start out with ...

thank you john , it really helps a lot！ I copy ana_sediment.h to my Project and edit it. The model can run a bit, but it still report an error I use oceanM and the output.log reports as follow: NLM: GET_STATE - Reading state initial conditions, 2010-01-01 00:00:00.00 (Grid 01, t = 0.0000, File: ...

hello John I do define the SSW_BBL : j. I follow your suggestion and add the # define ANA_SEDIMENT below the cpp option #define SSW_BBL #ifdef SSW_BBL # define ANA_SEDIMENT # define SSW_CALC_ZNOT # undef SSW_LOGINT # undef SSW_CALC_UB # undef SSW_FORM_DRAG_COR # undef SSW_ZOBIO # undef SSW_ZOBL ...

Make sure NBCFILES is defined. Some roms.in files have it, some do not. If using COAWST, you need to have it. hello Kate I state the nbcfiles in my .in file and it actually works. thank you so much! But here comes a new error: the output-log reports that it can not fine the grain_diameter in mycase ...

make sure you do not have NBCFILES listed twice or something like that.

yep， I state the nbcfiles in the .in file and it actually works ！
thank you so much！

hi john thanks for your reply so quickly！ the line 1629 in inp_decode.f90 is follow: ! Accumulate number of multi-files per each grid. ! Ncount(ifile,igrid)=Ncount(ifile,igrid)+1 and the line 1557 of read_phypar.f90 is： CASE ('BRYNAME') label='BRY - lateral open boundary conditions' Npts=load_s2d(Nva ...

hello everyone In recent day，I use the COAWST model （couple the ROMS and SWAN model）to simulate sediment transport. Before this ，I successfully run the Sed_floc_toy case. But when I actually run the real case, it report a segmentation fault in the very beginning. The problem is described in the below ...
