OpenPNM is a comprehensive framework for performing pore network simulations of porous materials.
For more details about the package can be found in the on-line documentation

The preferred way of installing OpenPNM is via Anaconda Cloud using:
conda install -c conda-forge openpnm
OpenPNM can also be installed from the Python Package Index using:
pip install openpnm
However, we don't recommend installing using pip
since pypardiso
, which is a blazing fast direct solver, is not available for Windows users who use Python 3.7+.
For developers who intend to change the source code or contribute to OpenPNM, the source code can be downloaded from Github and installed by running:
pip install -e 'path/to/downloaded/files'
The advantage to installing from the source code is that you can edit the files and have access to your changes each time you import OpenPNM.
OpenPNM requires the Scipy Stack (Numpy, Scipy, Matplotlib, etc), which is most conveniently obtained by installing the Anaconda Distribution.
The following code block illustrates how to use OpenPNM to perform a mercury intrusion porosimetry simulation:
import openpnm as op
pn = op.network.Cubic(shape=[10, 10, 10], spacing=0.0001)
geo = op.geometry.StickAndBall(network=pn, pores=pn.Ps, throats=pn.Ts)
Hg = op.phases.Mercury(network=pn)
phys = op.physics.Standard(network=pn, phase=Hg, geometry=geo)
mip = op.algorithms.Porosimetry(network=pn)
mip.setup(phase=Hg)
mip.set_inlets(pores=pn.pores(['left', 'right', 'top', 'bottom']))
mip.run()
The network can be visualized in ParaView
giving the following:
The drainage curve can be visualized with mip.plot_intrusion_curve()
giving something like this:

Github now has a Discussions function, which works similarly to stack overflow. Please post your question in the Q&A category so devs or users can provide answers, vote on accepted answers, improve on each other's answers, and generally discuss things. Most importantly, all answers are searchable so eventually, once enough questions have been posted and answered, you can find what you're looking for with a simple search.
OpenPNM is developed by the Porous Materials Engineering and Analysis Lab (PMEAL), in the Department of Chemical Engineering at the University of Waterloo in Waterloo, Ontario, Canada.
The lead developer for this project is Prof. Jeff Gostick (jgostick@gmail.com).
