Ocean Modeling Discussion

All,
Apologies for the blatant bump up of the above post, but we would greatly appreciate if the ROMS community have any insights to offer in relation to the MPI/tiling discrepancies identified between the various options for nesting in ROMS (in all it's incarnations)
Regards,
Alan.

Hi sittisak, There are a number of errors in your configuration, and as Kate pointed out above, ROMS can often tell you what the problem is if you only look at the output. In this instance: NETCDF_CHECK_DIM - inconsistent size of dimension: xi_u 43 513 in file: gulfthailand_grd.nc Your grid ...

Hi zongchen, I too had the same problem when compiling the WC13 test cases some time ago. : undefined reference to `dsteqr_' relates to ARPACK/LAPACK libraries which may need to be compiled and built (depending on your existing system set-up). These libraries then need to be correctly referenced in ...

Hernan, Thanks for the heads-up on the adjoint TS_MPDATA. We are commencing experiments with IS4DVAR to see if it can lead to improvements in our operational modelling capabilites. Initially we are setting up the IS4DVAR model with the same cppdefs as our op model to assess stability, compute times ...

Hi, I am using ROMS 3.7 (svn 678) checked out 31/07/2013 I have come across a few coding errors/omissions in various parts of the Adjoint model codes when trying to compile for my specific case study. The errors are cpp defintion specific, so may not have arisen to date on the bundled test cases ...

Hi Leif, I was hoping to modify the behavior module to have a vertical migration based on the age (time since day of birth) for each particle. However I know that the variable 'P_age' in behavior_module.f90 is just seconds since the model started. par(n,pAge), or P_age, is the time (seconds) since ...

Hi Karina, Last year we developed an oil module within the LTRANS model code (see forum posts relating to LTRANS), called OILTRANS. The LTRANS code is an off-line particle tracking module, using archived ROMS hydrodynamics, originally developed for larval transport. A paper describing the ...

Hi simion1232006, I have been using LTRANS for a while for a number of different purposes and have trouble-shooted (shot?) a lot of issues. I suggest that you decrease the idt value, internal particle tracking time step (s), to prevent the particle skipping through a computational cell. That should ...
