Hello, I am running a dynamic analysis model in Plaxis to find a vertical displacement of the pipeline in liquefiable soil, but it takes one day and is still running in 11.21 seconds. Is it normal for this kind of analysis in Plaxis? If so, anyone could…

While using PM4 models the effective stress calculation should be based on vu undrained or by using biot effective stress calculations as Pore pressure measurements and liquefaction criteria are the major concern?

if using 'Drained' for Drainage type in General and using PM4Sand in Mechanical tab as user defined, no pore pressures are generated in dynamic phase. Should I use 'undrained A' even for sand type material when using PM4 sand?

On using PM4silt for clay and using Undrained A and for sandy soils (PM4sand) Undrained A.is it correct to use this combination while studying for liquefaction analysis?

Since PM4sand and PM4 silt models are advanced constitutive models for dynamic analysis. I have read in one journal that for static analysis, they used Mohr-coulomb. Can we change the model after static analysis in one project? IS it possible?

Why liquefied points are observed in soil while using advanced constitutive models PM4sand and PM4silts before seismic loading? The liquefied points were observed in static phase only

I just doing a simulation for liquefaction on gentle relief slope with the dynamic load is 50s which consist 0.01s each data. I use PM4Sand for the constitutive model applied on the sand layer also HS Small for the clay. Currently I set the Max steps…

Good morning, Is it possible to set manually the value of the parameter h0 for the PM4Sand model? The value is computed internally with equation 2.31 of the PM4Sand model manual. Thank you in advance, Andrea Balia
