Tuple length matching error with mfhfb.py

[CynicalDonkey]

I am working with flopy 3.3.7 and attempting to load a fresh copy of the Texas Water Development Board central carrizo wilcox groundwater availability model, which is modflow-USG, to Spyder. After running flopy.mfusg.MfUsg.load(), I get the following error:

  File C:\anaconda3\lib\site-packages\flopy\modflow\mfhfb.py:326 in load
    specified[ibnd] = tuple(t[: len(specified.dtype.names)])

ValueError: could not assign tuple of length 3 to structure with 6 fields.

I've opened the mfhfb.py file to see if I can determine what is happening, but it's a bit beyond my comprehension. The section where the error in mfhfb.py is thrown from is below:

        # data set 4
        bnd_output = None
        if nhfbnp > 0:
            specified = ModflowHfb.get_empty(nhfbnp)
            for ibnd in range(nhfbnp):
                line = f.readline()
                if "open/close" in line.lower():
                    raise NotImplementedError(
                        "load() method does not support 'open/close'"
                    )
                t = line.strip().split()
                specified[ibnd] = tuple(t[: len(specified.dtype.names)])

Any help is appreciated.

Hi @CynicalDonkey I'll take a look at this in the next week or so.

@CynicalDonkey see PR #1686. Once/if accepted, you can update your flopy install to the latest develop branch and then be able to load your model, eg:

pip uninstall --yes flopy
pip install https://github.com/modflowpy/flopy/archive/refs/heads/develop.zip

Chris, Thanks very much for taking the time to address this and push a fix. If you have time at some point, I would love to have a general chat about the big picture view of what you changed. I have taken a look through the code commit, but it's a bit beyond my understanding at the moment. That is what I am working on though, and getting feedback or assistance from people who know their stuff, as it seems you do, always helps out a lot. Thanks, Wesley
