moving a particle through the laminar flow

I want to simulate the problem in which a sphere moves through a fluid and study its time dependent profile
but I can't move the sphere anyway. I used the moving boundary condition for particle walls and gave it velocity, but when I animate the velocity the sphere stands and does not move.
I think it is performed by "moving mesh" or "deformed geometry" but I don't know how it is.
comsol V.4.3
can you help me?
Thanks!

it's very important for me
please!

the moving mesh allows only to move the grid, if you want to perform an interaction between a solid and a fluid you should use the Fluid-Structure Interaction physics.
It has the equations and features for fluid-structure interaction, solving for the displacements, fluid velocity, and fluid pressure.
Have a good work.

you are right!
but if you want to make a deformed 2D geometry in which a sphere moves freely within a rectangular, what would you do?
