Questions about the saturation state

[Tianmeng818]

Dear Professor:
Hello! Previously in studying this article of yours from 2016 "OpenPNM: A Pore Network Modeling Package", I have successfully reproduced it in versions 2.8.2 and 3.1.2. This article has inspired me a bit.
In this article, the OrdinaryPercolation algorithm and the FickianDiffusion algorithm were successively used to realize water body intrusion and gas diffusion. In the article, after completing the OP algorithm to implement water body intrusion, a certain state of the result after completing the intrusion algorithm is used as the initial state for gas diffusion.
So is it possible to consider, after completing the OP algorithm, to use a certain state of the result as an initial state of another intrusion algorithm in the next step, I tried to carry out the implementation of non-saturated state intrusion in 2.8.2 and 3.1.2, for example, after completing the intrusion algorithm in the first step, to use 50% saturation in the process as the initial state of another intrusion algorithm in the second step, but after so long there is still not much progress, so I came to ask if there is any relevant example for reference.

In your "OpenPNM-Example/[Topology](https://github. com/mrokhfrooz/OpenPNM-Examples/tree/master/Topology)
The file "/generate_vorono_network.md" found the following code that would backtrack the saturation.

But I realized that this is 2016 code, and it doesn't use "return-result" in 2.8.2 and the latest v3 version, I guess it should use "update" instead, but nothing seems to have changed! I would like to be able to use "# Update the simulation until saturation is at 50%", is this still available in version 2.8.2 or v3? If so, is there a relevant example related to backtracking saturation that I can learn from?
