flopy.modflow.mfmnw1 Module

class flopy.modflow.mfmnw1.ModflowMnw1(model, mxmnw=0, ipakcb=None, iwelpt=0, nomoiter=0, kspref=1, wel1_bynode_qsum=None, itmp=0, lay_row_col_qdes_mn_multi=None, mnwname=None, extension='mnw1', unitnumber=None, filenames=None)

MODFLOW Multi-Node Well 1 Package Class.


model : model object

The model object (of type flopy.modflow.mf.Modflow) to which this package will be added.

mxmnw : integer

maximum number of multi-node wells to be simulated

ipakcb : integer

A flag that is used to determine if cell-by-cell budget data should be saved. If ipakcb is non-zero cell-by-cell budget data will be saved. (default is 0).

iwelpt : integer

verbosity flag

nomoiter : integer

the number of iterations for which flow in MNW wells is calculated

kspref : string

which set of water levels are to be used as reference values for calculating drawdown

losstype : string

head loss type for each well

wel1_bynode_qsum : list of lists

nested list containing file names, unit numbers, and ALLTIME flag for auxilary output, e.g. [[‘test.ByNode’,92,’ALLTIME’]]

itmp : array

number of wells to be simulated for each stress period (shape : (NPER))

lay_row_col_qdes_mn_multi : list of arrays

lay, row, col, qdes, and MN or MULTI flag for all well nodes (length : NPER)

mnwname : string

prefix name of file for outputting time series data from MNW1

extension : string

Filename extension (default is ‘mnw1’)

unitnumber : int

File unit number (default is 33).

filenames : string or list of strings

File name of the package (with extension) or a list with the filename of the package and the cell-by-cell budget file for ipakcb. Default is None.


Parameters are not supported in FloPy.

The functionality of the ADD flag in data set 4 is not supported. Also not supported are all water-quality parameters (Qwval Iqwgrp), water-level limitations (Hlim, Href, DD), non-linear well losses, and pumping limitations (QCUT, Q-%CUT, Qfrcmn, Qfrcmx, DEFAULT).


>>> import flopy
>>> ml = flopy.modflow.Modflow()
>>> mnw1 = flopy.modflow.ModflowMnw1(ml, ...)
check(f=None, verbose=True, level=1)

Check package data for common errors.


f : str or file handle

String defining file name or file handle for summary file of check method output. If a sting is passed a file handle is created. If f is None, check method does not write results to a summary file. (default is None)

verbose : bool

Boolean flag used to determine if check method results are written to the screen

level : int

Check method analysis level. If level=0, summary checks are performed. If level=1, full checks are performed.




>>> import flopy
>>> m = flopy.modflow.Modflow.load('model.nam')
>>> m.dis.check()
load(model, pack_type, f, nper=None, pop_key_list=None, check=True, unitnumber=None, ext_unit_dict=None)

The load method has not been implemented for this package.


Plot 2-D, 3-D, transient 2-D, and stress period list (MfList) package input data


**kwargs : dict

filename_base : str

Base file name that will be used to automatically generate file names for output image files. Plots will be exported as image files if file_name_base is not None. (default is None)

file_extension : str

Valid matplotlib.pyplot file extension for savefig(). Only used if filename_base is not None. (default is ‘png’)

mflay : int

MODFLOW zero-based layer number to return. If None, then all all layers will be included. (default is None)

kper : int

MODFLOW zero-based stress period number to return. (default is zero)

key : str

MfList dictionary key. (default is None)


axes : list

Empty list is returned if filename_base is not None. Otherwise a list of matplotlib.pyplot.axis are returned.


>>> import flopy
>>> ml = flopy.modflow.Modflow.load('test.nam')
>>> ml.dis.plot()
to_shapefile(filename, **kwargs)

Export 2-D, 3-D, and transient 2-D model data to shapefile (polygons). Adds an attribute for each layer in each data array


filename : str

Shapefile name to write




>>> import flopy
>>> ml = flopy.modflow.Modflow.load('test.nam')
>>> ml.lpf.to_shapefile('test_hk.shp')

Write the package file.
