Hi,

I have two 3-D rotating fluid circular zones both adjacent to one another. I am trying to do a moving reference frame motion where i need to add rotation to one zone and the other zone must rotate simultaneously due to coupling. So for the driving circular zone, i enabled frame motion, set motion to rotation and gave a certain rpm. Now what do i need to do for the adjacent fluid zone so that it rotates at a similar rpm to the driving zone?

Both zones are same fluid-water and share a mesh interface

Will selecting coupled wall in mesh interface help me in achieving my goal or will that have no effect on motion of the two bodies?

Kindly help

Thanks in advance

Do i check coupled walls in mesh interface menu? will that solve my purpose?

The coupled wall is a wall boundary with cells on both sides. If you want both cell zones to rotate at the same rate you need to set both with the same rotation axis and speed.

Thanks. I will try it out
