class ModflowMnw1(model, mxmnw=0, ipakcb=None, iwelpt=0, nomoiter=0, kspref=1, wel1_bynode_qsum=None, losstype='skin', stress_period_data=None, dtype=None, mnwname=None, extension='mnw1', unitnumber=None, filenames=None)[source]

Bases: Package

MODFLOW Multi-Node Well 1 Package Class.

Parameters:

  • 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 or None) – nested list containing file names, unit numbers, and ALLTIME flag for auxiliary output, e.g. [[‘test.ByNode’,92,’ALLTIME’]] if None, these optional external filenames and unit numbers are not written out

  • 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.

Notes

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).

Examples

>>> import flopy
>>> ml = flopy.modflow.Modflow()
