Hello everyone. I'm still working on dynamic simulation. I want to ask some situation I found.

Condition,

I have sine wave function, I applied it at the base model j=1 by using

apply yacc 1 xacc 1 his wave j=1

So, in here I just assign the ff boundary (side part) and the rigid boundary (fix x y, base modl).

The rsult shows the yacc drops earlier during the earthquake, but the xacc seems like have little bigger than the wave. I expect the xacc and yacc could be have smaller energy during dynam,ic simulation. But, the rsults didn't show up.

(I have applied damping rayleigh)

Other finding is, the model (All model) move in vrtical direction, ex first condition my model is in range y=1, 5 but after the dynamic simulation, the model move to y=3,7

do you any suggstion?

Thank you for seeing my question. I really appreciate your answers.
