Percolation pathsways

[JahanzebTariq]

Dear Professors @jgostick and @ma-sadeghi. Please tell me if there is a way in PNM to get the percolation pathways. If so then please guide me or at least direct me to an example.
Thank you in advance

[jgostick]

When you run either invasion percolation or drainage, one of the arrays that get calculated is called 'pore.invasion_sequence'. This tells you which order each pore was invaded in. With invasion percolation each pore (and throat) are numbered uniquely since the process occurs in individual steps, while in drainage (ordinary percolation), there are groups of pores and throats that are invaded at the same time.

But how can I visualize these pathways ... can you please refer an example

[jgostick]

Paraview? Then you can color the throats by their invasion sequence, and even do a movie by changing the threshold value. I'm sorry but we don't have an example of this.

@jgostick .. sir I tried to do what you said but I came across this error

please help me with this one.. thank you
