Translating a 2D solid body in 2D domain

Hello all, is there any possible ways to translate a solid body in fluid domain with a particular velocity without using UDF. I tried using mesh and frame motion but I end with un-successful attempts.

In post processing, one sphere remains stagent and other copy of it moves with defined velocity. How to resolve it.

Thanks in advance.

The purple arrow shows the original circle, but during animation this remains fixed but a copy of it moves as in black arrow and spoils the animation.
