How to use Flow-Ja-Face file to draw the flow direction figure

[Sakura223Leslie]

The latest version of flow- ja- face dose not have the flow right/left face. How we can use flow-ja-face file to draw the flow direction figure? Thanks!

Take a look at flopy.mf6.utils.postprocessing.get_structured_faceflows() to get the face flows for the flow right face, flow front face, and flow lower face from the MODFLOW 6 flowja flows. You can see examples how to use it with test_postprocessing.py, e.g.:

    mf6_cbc = gwf.output.budget()
    mf6_flowja = mf6_cbc.get_data(text="FLOW-JA-FACE")[0]
    mf6_frf, mf6_fff, mf6_flf = get_structured_faceflows(
        mf6_flowja,
        grb_file=mf6_ws / "freyberg.dis.grb",
    )
