Controlling 2D FLUID motion during collision

Hi guys, i'm trying to mix 2 colors inside a container using 2D Fluid. Basically i animated a sphere to dive into the fluid.... and colliding with the fluid. The fluid, which i mapped with an image (painted in 2 colors) to simulate the density and color.

The animation of the sphere is quite fast, when colliding with the fluid, i found that it's like it is 'digging' into the fluid. The fluid is not 'joining' back smoothly after collided with the sphere. Is there anyway to control the 2D fluid motion during the collision? (sorry for my bad english)

you could try to add a field to help push the fluid out of the way, if that's what your asking

You can do fluids->createMotionField. This will cause the object to push the fluid as it moves.
