https://communities.bentley.com/products/geotech-analysis/f/forum/215161/dynamic-pore-pressuresHi, I am modelling a largescale oedometer(like) setup with dynamic loading. I have tried different soil models (soft soil,MCC, Hardening,HS small etc) to simulate the dynamic behaviour but unable to produce the excess pore pressure accumulation.

That is not MC, Soft Soil, MCC, HS or HSsmall .... they&#39;re all static models. You would have to use UBC3DPLM, PM4Sand or PM4Silt as those are models for cyclic loading and potentially liquefaction</p> <p>With kind regards,</p> <p>Dennis Waterman</p><div style="clear:both;"></div>
