Inquiry on Modifying Anura3D to Import FEM Stress, Saturation, and Pore Pressure

[stig-cz]

Hi everyone,

I'm currently working with Anura3D for slope failure simulations and am exploring the possibility of modifying the code to import variables (such as stress, strain, saturation, and pore water pressure) from external FEM simulations like PLAXIS into the MPM stage of Anura3D. The idea is to initialize the material points in Anura3D with these pre-computed FEM results.

I’d like to know if it’s feasible to implement this in Anura3D and, if so, which files or modules would be most relevant to modify. Additionally, any advice on the best approach or potential challenges to keep in mind would be greatly appreciated.

Thank you in advance for any insights or guidance!

Best regards,
Chongzhi Wu

Yes, you can, this is a quick comment, to get you started, not a full answer.

If you look in the 2024 tutorial, you will find

and
13.3.1.7 after the figures something it is explicitly mentioned Phreatic Surface → Water table from file PSF_1
