I want to apply (input) a dynamic load of sinusoidal wave which is having a frequency of 20hz and amplitude of 5m/s2 at the base of model how can I apply that? Secondly, how can I use UBC3DPLM model for liquefaction and how can I get pre and post liquefaction…

I have modelled one combined piled raft foundation using raft as plate and pile as embedded beam element and applied one sinusoidal loading with frequency 1 Hz and acceleration amplitude 1 m/s2 for 30 second interval at the soil model base in surface…
