soil-retaining wall interface

[Rubinsa]

Hi all,
Is it possible to model soil-retaining wall interface using Py-Tz-Qz contacts ? Is there an example for that? Currently I'm using BeamContact2D, but I guess It doesn't work properly at the toe of the wall.

As of my last knowledge update in September 2021, Py-Tz-Qz contact types are not directly available in the context of soil-retaining wall interfaces within widely used numerical modeling software packages such as Abaqus or ANSYS. These contact types appear to be specific to certain geotechnical modeling software like FLAC (Fast Lagrangian Analysis of Continua) or similar tools that are tailored for geotechnical engineering simulationsmonopoly online

Thank you very much for your response.
Based on your experience, which interface elements available in OpenSees works better for soil-retaining wall interface?
