External file handling

# make a model
nlay, nrow, ncol = 10, 20, 5
temp_dir = TemporaryDirectory()
model_ws = temp_dir.name
# the place for all of your hand made and costly model inputs
array_dir = os.path.join(temp_dir.name, "array_dir")
os.mkdir(array_dir)
ml = flopy.modflow.Modflow(model_ws=model_ws)
dis = flopy.modflow.ModflowDis(
ml, nlay=nlay, nrow=nrow, ncol=ncol, steady=False, nper=2
)
make an hk and vka array. We’ll save hk to files - pretent that you spent months making this important model property. Then make an lpf
[3]:
hk = np.zeros((nlay, nrow, ncol)) + 5.0
vka = np.zeros_like(hk)
fnames = []
for i, h in enumerate(hk):
fname = os.path.join(array_dir, f"hk_{i + 1}.ref")
fnames.append(fname)
np.savetxt(fname, h)
vka[i] = i + 1
lpf = flopy.modflow.ModflowLpf(ml, hk=fnames, vka=vka)
Let’s also have some recharge with mixed args as well. Pretend the recharge in the second stress period is very important and precise
[4]:
warmup_recharge = np.ones((nrow, ncol))
important_recharge = np.random.random((nrow, ncol))
fname = os.path.join(array_dir, "important_recharge.ref")
np.savetxt(fname, important_recharge)
rch = flopy.modflow.ModflowRch(ml, rech={0: warmup_recharge, 1: fname})
[5]:
ml.write_input()
Let’s look at the files that were created
[6]:
from pprint import pprint
print("model_ws:", flopy_io.scrub_login(ml.model_ws))
pprint([flopy_io.scrub_login(p) for p in os.listdir(ml.model_ws)])
model_ws: /tmp/tmpwusc57hq
['hk_6.ref',
'hk_7.ref',
'array_dir',
'modflowtest.nam',
'modflowtest.lpf',
'hk_9.ref',
'modflowtest.dis',
'modflowtest.rch',
'hk_10.ref',
'hk_2.ref',
'hk_5.ref',
'hk_8.ref',
'hk_1.ref',
'hk_3.ref',
'important_recharge.ref',
'hk_4.ref']
We see that a copy of the hk files as well as the important recharge file were made in the model_ws.Let’s looks at the lpf file
[7]:
open(os.path.join(ml.model_ws, f"{ml.name}.lpf")).readlines()[:20]
[7]:

We see that the open/close approach was used - this is because ml.array_free_format is True. Notice that vka is written internally
[8]:
ml.array_free_format
[8]:
True
Now change model_ws
[9]:
ml.model_ws = os.path.join(model_ws, "new_external_demo_dir")
creating model workspace...
../../../../../../../tmp/tmpwusc57hq/new_external_demo_dir
Now when we call write_input(), a copy of external files are made in the current model_ws
[10]:
ml.write_input()
[11]:
# list the files in model_ws that have 'hk' in the name
print(
"\n".join(
[
name
for name in os.listdir(ml.model_ws)
if "hk" in name or "impor" in name
]
)
)
hk_6.ref
hk_7.ref
hk_9.ref
hk_10.ref
hk_2.ref
hk_5.ref
hk_8.ref
hk_1.ref
hk_3.ref
important_recharge.ref
hk_4.ref
Now we see that the external files were copied to the new model_ws
Using external_path
It is sometimes useful when first building a model to write the model arrays as external files for processing and parameter estimation. The model attribute external_path triggers this behavior
[12]:
# make a model - same code as before except for the model constructor
nlay, nrow, ncol = 10, 20, 5
model_ws = os.path.join(model_ws, "external_demo")
os.mkdir(model_ws)
# the place for all of your hand made and costly model inputs
array_dir = os.path.join(model_ws, "array_dir")
os.mkdir(array_dir)
# lets make an external path relative to the model_ws
ml = flopy.modflow.Modflow(
model_ws=model_ws, external_path=os.path.join(model_ws, "ref")
)
dis = flopy.modflow.ModflowDis(
ml, nlay=nlay, nrow=nrow, ncol=ncol, steady=False, nper=2
)
hk = np.zeros((nlay, nrow, ncol)) + 5.0
vka = np.zeros_like(hk)
fnames = []
for i, h in enumerate(hk):
fname = os.path.join(array_dir, f"hk_{i + 1}.ref")
fnames.append(fname)
np.savetxt(fname, h)
vka[i] = i + 1
lpf = flopy.modflow.ModflowLpf(ml, hk=fnames, vka=vka)
warmup_recharge = np.ones((nrow, ncol))
important_recharge = np.random.random((nrow, ncol))
fname = os.path.join(array_dir, "important_recharge.ref")
np.savetxt(fname, important_recharge)
rch = flopy.modflow.ModflowRch(ml, rech={0: warmup_recharge, 1: fname})
We can see that the model constructor created both model_ws and external_path which is relative to the model_ws
[13]:
os.listdir(ml.model_ws)
[13]:
['array_dir', 'ref']
Now, when we call write_input(), any array properties that were specified as np.ndarray will be written externally. If a scalar was passed as the argument, the value remains internal to the model input files
[14]:
ml.write_input()
# open(os.path.join(ml.model_ws, ml.name + ".lpf"), "r").readlines()[:20]

Now, vka was also written externally, but not the storage properties.Let’s verify the contents of the external path directory. We see our hard-fought hk and important_recharge arrays, as well as the vka arrays.

ml.lpf.ss.how = "internal"

Fixed format
All of this behavior also works for fixed-format type models (really, really old models - I mean OLD!)
[17]:
# make a model - same code as before except for the model constructor
nlay, nrow, ncol = 10, 20, 5
# lets make an external path relative to the model_ws
ml = flopy.modflow.Modflow(model_ws=model_ws, external_path="ref")
# explicitly reset the free_format flag BEFORE ANY PACKAGES ARE MADE!!!
ml.array_free_format = False
dis = flopy.modflow.ModflowDis(
ml, nlay=nlay, nrow=nrow, ncol=ncol, steady=False, nper=2
)
hk = np.zeros((nlay, nrow, ncol)) + 5.0
vka = np.zeros_like(hk)
fnames = []
for i, h in enumerate(hk):
fname = os.path.join(array_dir, f"hk_{i + 1}.ref")
fnames.append(fname)
np.savetxt(fname, h)
vka[i] = i + 1
lpf = flopy.modflow.ModflowLpf(ml, hk=fnames, vka=vka)
ml.lpf.ss.how = "internal"
warmup_recharge = np.ones((nrow, ncol))
important_recharge = np.random.random((nrow, ncol))
fname = os.path.join(array_dir, "important_recharge.ref")
np.savetxt(fname, important_recharge)
rch = flopy.modflow.ModflowRch(ml, rech={0: warmup_recharge, 1: fname})
ml.write_input()

We see that now the external arrays are being handled through the name file. Let’s look at the name file

The .how attribute
Util2d includes a .how attribute that gives finer grained control of how arrays will written
[22]:
ml.lpf.hk[0].how
[22]:
'external'
This will raise an error since our model does not support free format…
[23]:
try:
ml.lpf.hk[0].how = "openclose"
ml.lpf.hk[0].how
ml.write_input()
except Exception as e:
print("\n", e, "\n")
Util2d:delr: resetting 'how' to external

So let’s reset hk layer 1 back to external…
