Hello,

We have a segmented dataset with a tube that is straight up and down and a curved tube.

When we crop to only focus on the center tube, we get a tortuosity of approximately 1.004, which is consistent with the definition of tortuosity.

However, when we run the same diffusion simulation on the curved segment, we repeatedly get 1.001. We have tried to crop out part of the top section, clean up the sample, and erode the dataset to get a focused centerline for the path to follow. None of these changed the value from 1.001.

Are there any other methods to get an accurate result for tortuosity? Thank you.

Respectfully,
Jack Davis

Hi,

for diagonal pores as shown in the attached image the tortuosity computed with DiffuDict is as expected.

All alternative methods to compute tortuosity can be accessed through the Tortuosity app ( see https://geodict-userguide.math2market.de/2025/geoapp_computetortuosity.html )
