Mesh motion for two bodies

siw

Hi,

I have a simulation whereby I have a fluid domain with 2 solid bodies in it. Both bodies are in contact and one body moves away from the other over time. Therefore, I need to use the mesh motion/deformation features of CFX.

As a test on mesh motion before this 2 body task I tried mesh motion on 1 body and immersed the body in a sphere. The sphere would then translate and rotate.

But I don't know the best way to have a mesh around 2 bodies, knowing that one will move from the other.

Would appreciate help. Thanks.
