Ocean Modeling Discussion

Thanks for the quick response, Arango. I understand that parallelism won’t be possible in the time-stepping equations or algorithms. However, my question was more about the distribution of grids across processors. For example, in the case of telescoping grids, we have a global grid followed by s ...

Dear all, I have been looking into the parallelization of the ROMS model, specifically the case of nested grids. From what I understand, the current processor distribution strategy involves distributing all the grids present in a nesting application across all the processes spawned for that ...

I'm getting similar error while running a nested application case. The error is TIDES_DATE - Variable index not yet loaded, idTref Update your metadata file: /scratch/cdschai/ROMS_Working/nested_Bob_Exp/varinfo.dat Found Error: 05 Line: 136 Source: ROMS/Utility/tides_date.F Found Error: 05 Line: 211 ...

In an attempt to create a NESTED GRID application, using the same nested grid example(Lake Jersey). I considered the same coarser grid as in the given application named (a grid), using the coarse2fine function I created a grid in the same region as b gird but with more finer resolution. I was ...

Hey, I have a doubt regarding setting up of nested grid applications. How can initial files for finer grid be generated from the coarser grid? Can we just use roms2roms function to get initial file for the finer grid from a coarser grid initial file. or we need to run for the coarser grid first and ...

Hi,
I am working with the lake jersey nested grid example, in which there are MATLAB scripts to interpolate the grid information and the connection information.
Similarly are there any scripts which can interpolate initial condition files from the originally given a,b,c,d,e initial files?
Thank you.

I'm facing an issue while scaling any nested grid application beyond 144 processors. The error which is displayed is : INP_PAR - domain decomposition error in input script file for grid: 01 The domain partition parameter, NtileJ = 15 is incompatible with grid size, Mm = 80 because it yields too ...
