barotropic module not found

[met-sree]

Hi everyone,

I’m new to model2roms and have followed these steps so far:

1. I downloaded the model2roms repository.

2. Navigated into the folder using cd model2rom.

3. Created a conda environment named model2roms and installed the required packages as mentioned in README.md.

4. Compiled the code using python compile.py, and it generated three .so files in the same folder.

Now, when I try to run python runM2R.py, I get the following error: "barotropic module not found"

Could you please help me resolve this issue or suggest any steps to fix it?

Thank you,
Sree

Thank you all, the issue has been resolved. The problem was related to the latest versions of Python, which are unable to load .so files correctly.

Now, I am trying to prepare initial and boundary conditions for a 5-day simulation using a single SODA 5-day dataset file. However, I encountered another error related to ESMF while running configM2R.py.

The data and grid files are attached at the link below for your reference. I would appreciate any suggestions or solutions to help resolve this issue.

Please provide an error log and Ill look at the problem. T

Thank you Sir for your reply. For your reference, I have attached two log files: the error log generated by running python runM2R.py >& error.log &, and the default PET0.ESMF_LogFile. As per my knowledge, I am aware of only these log files. If any additional files are needed to help diagnose the issue, please let me know.

I think there is an issue with your grid. Could you try the following:

1. Try with a different grid to see if the code generates forcing correctly using the same settings.
2. Add ignore_degenerate=True, to the regrid function call such as in interp2D.py:

confM2R.grdROMS.regridSrc2Dst_rho = ESMF.Regrid(
        confM2R.grdMODEL.fieldSrc_rho,
        confM2R.grdROMS.fieldDst_rho,
        regrid_method=ESMF.RegridMethod.BILINEAR,
        unmapped_action=ESMF.UnmappedAction.IGNORE,
        ignore_degenerate=True,
    )

Not sure if the latter will have an effect but worth trying.

As per your suggestions, I added the line to the regridSrc2Dst_rho function, but the error still persists. For further testing, I also added the same line to the regridSrc2Dst_u and regridSrc2Dst_v functions, which allowed the script to progress further. However, it then encountered another error, which I have attached below.

Based on my understanding, now the issue seems to be related to the input data (SODA-5day). My ultimate goal is to prepare initial and boundary conditions using HYCOM daily data. I initially chose the SODA 5-day dataset just to understand the workflow.

Is there any possibility of using HYCOM data with this setup?

You have to modify the code to be able to read the 5-day SODA data at the correct place. Add a debug statement where you print the filename generated in `getSODA3_5DAYfilename` by model2roms and see if you need to change anything to read where you store your files.
