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
