Explicitly Dynamic Animation does not show time domain response as it is. 

(Although result / history output XY plot is possible)

Abacus animate only displacement at the end of time period.

Animation is a single cycle of linear movement between initial condition and last condition.

For example,

Time period set:  .                        1.0 second

Natural frequency of structure:        10 / second

Period                                          0.1 second

User defined time increment:        0.01 second

If I scroll the frame selector, 10 sin curve with 100 frame should be available.

However, only there are only 2 frame selector, first and last.

Frame selector and animation mislead users.

It should show time domain response as it is. 

Please advise me how to see real time domain movement on screen.
