Tutorial to get the relative permeability curves

[minzhangut]

I am wondering whether there is a tutorial that I can refer to simulate two-phase flow in the pore network and obtain the relative permeability curves. Thanks!

There are two here: https://github.com/PMEAL/OpenPNM/tree/dev/examples/simulations/percolation

One shows how to use the metrics class, which tries to do it for you. The other one does relative diffusivity but the idea is the same, use StokesFlow instead of FickianDiffusion.

I tried to follow this example: https://github.com/PMEAL/OpenPNM/blob/dev/examples/simulations/percolation/relative_permeability_metrics.ipynb
I installed the dev versions of both porespy and openpnm.

When I tried to run:
rp = op.algorithms.metrics.RelativePermeability(network=pn)

I got the error of complaining AttributeError: module 'openpnm.algorithms' has no attribute 'metrics'

So I am wondering which algorithm I could use to calculate the relative permeability curves?

I got the error of complaining AttributeError: module 'openpnm.algorithms' has no attribute 'metrics'

This means that you didn't install the last version of openpnm, install the dev version directly from git so that you will get the full package

I just installed the latest dev version of openpnm using "pip install git+https://github.com/PMEAL/OpenPNM.git@dev". But I still got the same error. Also, from the Module Reference, I did not see 'metrics' in 'openpnm.algorithms'. From the Module Reference, I saw 'openpnm.metrics', but I did not see "RelativePermeability" there.

This the version I have 2.8.2 , and there is Relativepermeability.py

I tried openpnm 2.8.2, I had a different error (and that's why I was directed to the installation of the openpnm dev version):
