Introduction

FloPy includes support for MODFLOW 6, MODFLOW-2005, MODFLOW-NWT, MODFLOW-USG, and MODFLOW-2000. Other supported MODFLOW-based models include MODPATH (version 6 and 7), MT3DMS, MT3D-USGS, and SEAWAT.

For general modeling issues, please consult a modeling forum, such as the MODFLOW Users Group. Other MODFLOW resources are listed in the MODFLOW Resources section.

Installation

FloPy requires Python 3.8 (or higher), NumPy 1.15.0 (or higher), and matplotlib 1.4.0 (or higher). Dependencies for optional FloPy methods are summarized here.

To install FloPy type:

conda install -c conda-forge flopy

or

pip install flopy

The release candidate version can also be installed from the git repository using the instructions provided below.

After FloPy is installed, MODFLOW and related programs can be installed using the command:

get-modflow :flopy

See documentation get_modflow.md for more information.

Documentation

Documentation is available on Read the Docs and includes information on FloPy; tutorials for using FloPy with MODFLOW 6 and previous versions of MODFLOW, MT3DMS, MT3D-USGS, MODPATH, and ZONEBUDGET; and code documentation.

Getting Started

MODFLOW 6 Quick Start

import flopy
ws = './mymodel'
name = 'mymodel'
sim = flopy.mf6.MFSimulation(sim_name=name, sim_ws=ws, exe_name='mf6')
tdis = flopy.mf6.ModflowTdis(sim)
ims = flopy.mf6.ModflowIms(sim)
gwf = flopy.mf6.ModflowGwf(sim, modelname=name, save_flows=True)
dis = flopy.mf6.ModflowGwfdis(gwf, nrow=10, ncol=10)
ic = flopy.mf6.ModflowGwfic(gwf)
npf = flopy.mf6.ModflowGwfnpf(gwf, save_specific_discharge=True)
chd = flopy.mf6.ModflowGwfchd(gwf, stress_period_data=[[(0, 0, 0), 1.],
                                                       [(0, 9, 9), 0.]])
budget_file = name + '.bud'
head_file = name + '.hds'
oc = flopy.mf6.ModflowGwfoc(gwf,
                            budget_filerecord=budget_file,
                            head_filerecord=head_file,
                            saverecord=[('HEAD', 'ALL'), ('BUDGET', 'ALL')])
sim.write_simulation()
sim.run_simulation()

head = gwf.output.head().get_data()
bud = gwf.output.budget()

spdis = bud.get_data(text='DATA-SPDIS')[0]
qx, qy, qz = flopy.utils.postprocessing.get_specific_discharge(spdis, gwf)
pmv = flopy.plot.PlotMapView(gwf)
pmv.plot_array(head)
pmv.plot_grid(colors='white')
pmv.contour_array(head, levels=[.2, .4, .6, .8], linewidths=3.)
pmv.plot_vector(qx, qy, normalize=True, color="white")

Questions

FloPy usage has been growing rapidly, and as the number of users has increased, so has the number of questions about how to use FloPy. We ask our users to carefully consider the nature of their problem and seek help in the appropriate manner.

Do not open issues for general support questions. We want to keep GitHub issues for bug reports and feature requests. General support questions are better answered in the Discussions on the FloPy GitHub repository. Stack Overflow and the MODFLOW google group are other options but currently neither of these are as active as Discussions on the FloPy GitHub repository. If using Stack Overflow, questions should be tagged with tag flopy.

To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow or the MODFLOW google group.

Contributing

Bug reports, code contributions, or improvements to the documentation are welcome from the community. See the developer docs to begin. Please also read up on our guidelines for contributing and check out our issues in the hotlist: community-help.
