Make sure to select the Auto Fill option for the object.

If your 3D particle generation shows filled particles but the 2D view does not, it likely means your cutting section does not pass through the object’s center. (The Auto Fill option places the filled center at the object’s geometric center by default.)

If that’s the case, simply move your cutting section so that it passes through the center.
However, if you specifically need the current cutting position, use the Fill Box option instead. This allows you to manually define the filled center, which should be placed on the cutting surface.

I would like to know from 3D i want to convert to 2D but based on the particle generation why there is no particle out of the parameter (i already put autofill for the model as well)

@madelestin You can visualise GeoXPM outputs directly in ParaView.

For the image in SRF.png, I simply checked the accumulated plastic strain to identify the failure circle, took a screenshot, and repeated this for different SRF values. I then combined them manually.

Alternatively, you can import the output files from all SRF runs into ParaView to create an animation if preferred.

@tienlk2004

may i know how to plot as the attached picture that you attached before, the SRF.png?

Hi @13137990154,

You can enter the Strength Reduction Factor (SRF) in the material properties dialogue, as demonstrated in the 2D Granular Flow simulation provided in this example: (https://geoxsph.com/wp-content/uploads/2023/03/2D-Granular-flow-tutorial-1.pdf).

With GeoXPM, you can set up and run multiple problems with different SRF values and compare the results to identify when and where the failure plane forms, and also the post-failure behaviours (see the attached picture)

How to use this software to carry out stability analysis of two-dimensional slope (strength reduction method)
