in my model, the parameter PHASE:=0
EQ.0. Velocities applied immediately

but if I understand the calculation results correctly, then ls-dyna solves the problem with the parameter PHASE:=0 EQ.1. Velocities applied after dynamic relaxation.

and with this ls-dyna somehow independently calculates the period of dynamic relaxation and for some reason it also changes the amplitude/magnitude of the initial velocity that I set.
