Kinematic Boundary Condition.

Consider a body moving in an infinite fluid domain, as illustrated by figure 1.


  
Figure: Rigid body translating at constant speed $\vec{U}$ in an unbounded fluid domain.

We would like to know the flow field $\vec{v}$ generated by the body motion. How we can proceed?
