MF6 Execution Error in FloPy

[Kamalakanta Sahu]

Dear All,

I'm trying to run my modflow model in Jupyter Notebook, however, it seems like it's not able to run the mf6 executable file (mf6.exe)

Problem: the program mf6 does not exist or is not executable.

If possible can anyone help me out.

Thanks and Regards

Hello,

Have you set the right file path to the executable? Could you copy your code here, so it would be easier to identify the error?

Cheers,

Angelo.

Thank you Angelo for your response.

Code:

success, buff = sim.run_simulation()

if not success: 

   raise Exception("MODFLOW 6 did not terminate normally.")

Hi Kamalakanta,

Way before calling the simulation, when you create the simulation object, like:

sim = flopy.mf6.MFSimulation( sim_name=name, exe_name="mf6", version="mf6", sim_ws="." )

You must have downloaded the MF6 executable from its webpage (https://www.usgs.gov/software/modflow-6-usgs-modular-hydrologic-model) and copy/move the .exe file into the same folder where you are running the code. You can also point to it by changing the location through exe_name. Let's say it is in C:/WRDAPP/mf6.3.0/bin/, so:

sim = flopy.mf6.MFSimulation( sim_name=name,  exe_name="C:/WRDAPP/mf6.3.0/bin/mf6.exe" , version="mf6", sim_ws="." )

Hope it helps you.
