FloPy is a Python package to create, run, and post-process MODFLOW-based models.
Project description
Introduction
FloPy3 includes support for MODFLOW-2000, MODFLOW-2005, and MODFLOW-NWT. Other supported MODFLOW-based models include MODPATH (version 6), MT3D and SEAWAT.
FloPy3 Changes
FloPy3 is significantly different from FloPy2 (hosted on googlecode). The main changes are:
FloPy3 is fully zero-based. This means that layers, rows and columns start counting at zero. The reason for this is consistency. Arrays are zero-based by default in Python, so it was confusing to have a mix.
Input for packages that take layer, row, column, data input (like the wel or ghb package) has changed and is much more flexible now. See the notebook flopy3boundaries
Support for use of EXTERNAL and OPEN/CLOSE array specifiers has been improved.
load() methods have been developed for all of the standard MODFLOW packages and a few less used packages (e.g. SWI2).
MODFLOW parameter support has been added to the load() methods. MULT, PVAL, and ZONE packages are now supported and parameter data are converted to arrays in the load() methods. MODFLOW parameters are not supported in write() methods. MULT package FUNCTION and EXPRESSION functionality are not currently supported.

Examples
IPython Notebook Examples
The following IPython Notebooks contain example FloPy scripts for a variety of models and FloPy features
Basic examples
The lake example, a very simple FloPy3 example of steady flow in a square model with a fixed head cell in the middle (representing a lake) in a 10-layer model.
An overview of the options to enter layer,row,column,data values for packages such as the wel and ghb packages is given in the flopy3boundaries Notebook
The Henry Problem, a simple saltwater intrusion model developed with Flopy and run using SEAWAT.
SWI2 examples
Example 1 of the SWI2 manual, simulating a rotating interface.
SWI2 Test Problems for FloPy3
A zip file containing FloPy3 scripts for running and post-processing the SWI2 Examples (examples 1 to 5) that are described in Bakker et al. (2013) is available at:
Note that examples 2 and 5 also include FloPy3 scripts for running and post-processing SEAWAT models.
