Correct dynamic zones
 

Dear All,

I am modeling a longitudinally expanding duct with dynamic mesh.
In the dynamic zones, I define
- the duct walls as "deforming"
- the moving wall as "rigid body"

I do not define anything else here. Is this a correct zone setup?
Thank you for your help.

There isn't just one way to threat such model.
You can preview the mesh motion, you will see if everything is ok

The mesh motion is as expected. Does this guarantee the zones are correct?

if you don't have any warning about cell quality etc.. then yes

mAx,

thank you for your input.
