parallelize Flopy GWF model with MF6Splitter #2316

Hey there,

I am trying to use Flopy to run a MODFLOW6 model in parallel. I managed to split my model into many different models with the function MF6Splitter and reassemble the output by following this guide: https://flopy.readthedocs.io/en/latest/Notebooks/mf6_parallel_model_splitting_example.html.

My aim is to use multiple processors on my Windows laptop. However, my MODFLOW6 model appears to run in sequential mode, even though I followed the guide linked above. Any help would be greatly appreciated!

Cheers, Douwe

We have seen problems when people have run models from OneDrive locations. I am not sure if this is the issue here. We have run the compiled executable on Windows 10 and 11 OSs without issues.

You need to

Modify .run_simulation(silent=False) to .run_simulation(processors=number_of_partitions, silent=False), where number_of_partitions is the number of parallel partitions.
Download mf6.5.0_win64par.zip from the latest release at:

https://github.com/MODFLOW-USGS/modflow6/releases/tag/6.5.0

or win64par.zip from the MODFLOW 6 nightly build github repo at:

https://github.com/MODFLOW-USGS/modflow6-nightly-build/releases/

You do not have this version. You will need to unzip the contents of the zip file to a directory in your path.

You can also get the parallel version of MODFLOW for Windows using flopy:

flopy.utils.get_modflow(
        ":python", repo="modflow6-nightly-build", ostag="win64par", force=True
    )

The example above is downloading the nightly build in the python environment running the script/notebook. You can also use get_modflow() to download the release version using repo="modflow6".

Hey @jdhughes-usgs, thanks a lot for helping me.

I have implemented the changes you suggested. I am definitely a step further, but unfortunately I encountered an OSError.

I implemented your suggestions as follows:
1)
success, buff = new_sim.run_simulation(silent=True, processors=8)
2)

flopy.utils.get_modflow(
    ":python", repo="modflow6-nightly-build", ostag="win64", force=True
) 

# test version correct
mf6_exe = flopy.which("mf6")  # Get path of the installed MODFLOW 6 executable
if mf6_exe:
    os.system(f"{mf6_exe} --version")
else:
    print("MODFLOW 6 executable not found.")

Where I changed ostag="win64par" to ostag="win64", because of the following error:
KeyError: "unrecognized ostag 'win64par'; choose one of ['linux', 'mac', 'win32', 'win64']"

My new full code is:

@DouweKamper sounds like you have an older FloPy, I think the get-modflow utility supports the Windows parallel build in 3.7+

@wpbonelli thank you. You are right! I sillily did not consider this. My Flopy version was 3.6.0, now upgraded to 3.8.1. Now I can use the get-modlow exactly as @jdhughes-usgs suggested.

Unfortunately the following OSError still persists:

FloPy is using the following executable to run the model: ..\..\..\..\..\..\..\..\..\..\logbook5\Scripts\mf6.exe
FloPy is using C:\Users\Douwe\OneDrive - Wageningen University & Research\Documents\Docs MEE\MSc jaar 2\MSc Thesis\code\methods_thesis\Python\log_book\logbook5 Parallelize MODFLOW6 on Windows\mpiexec to run C:\Users\Douwe\logbook5\Scripts\mf6.exe on 8 processors.

We have seen problems when people have run models from OneDrive locations. I am not sure if this is the issue here. We have run the compiled executable on Windows 10 and 11 OSs without issues.

@jdhughes-usgs thank you for your suggestion. Running my models from my C:\ directory instead of OneDrive allowed me to run MODFLOW in parallel!
